Nice to see RB video. I asqed for it last video. And i have been w8ting more then half a year.

I think I have some "normal" schizophrenia about this video, because I love both the Nissans and the Toyotas (JDM alert😁). For that I have a MK3 MR2 being restored (maybe turbocharged?🤔) and a 350z used as a daily. Therefore I can't wait to see your upcoming videos (maybe about the VQ...😜). But can't agree with your more. I'd take a Skyline over a Supra just because of the driveability. If I'd want straight line power, I'd go for an LS or a Hemi. Keep up the good work mate, can't wait to see your turboed mk1 firing up😉.
just promoting products. and AEM in that regard is ok. but there are much better options out there. So no RB is not better , and the AEM is a poor choice as well. really bad video man. honestly saying. loved your videos before. but you kind of went to a level where you don't have the experience , and just make you look dumb.
@@vex9701 I've always been an RB26 fan ever since my first year of highschool, but I've always feared the 2J. Like bro i used to literally feel anxiety whenever i thought about the 2J. It just had so much damn power that it made me faulter at times when i watched RB videos. Those were scary times man.
So in conclusion, use the engine designed for your purposes. If you want an engine designed specifically for racing, use the engine designed for that. If you want the engine designed to survive anything (ie high horsepower) then use that. It really is a lesson to take into the wider world, in my opinion. Far too many people want to simplify things down to "x is better" or "you must do y" when there's always benefits and drawbacks for specific applications.
A really thoroughly researched comparison on these two engines, down here in Australia we absolutely love both of these engines, the RB in both drag racing and touring cars being very successful and the 2J predominantly in drag racing. We have a great after market support base for both engines, yet recently we are falling in love with our own locally designed in line 6 cylinder twin cam turbo engine, the Barra! We are seeing crazy numbers coming out of Barra engines on the dyno, thanks for the great video mate...
The Barra is only good for one thing power and unusable torque, As it should its a 4L six that copied the head and port design of the 2j and RB. Good enough motor but they get too much credit for what they actually are. Once again a engine raved about because it can make power relatively easily. Fun fact no barra has ever beat the RB or 2J maximum hp number. lol
I dont want to upset Americans, Australians and the whole lot where drag racing is popular. But it's 10 seconds at .most. It's intense, it's fun but it's a humiliation to use a combustion engine for that, a combustion engine is overqualified for that job. I swear by god I can win that with a spring powered car or a water rocket shopping cart. It's only the designation as racing with rules that keeps the combustion engines still relevant in drag racing. Springs, catapults, electric motors, rockets, any other device is more qualified to discharge lots of power in a short time.
@@clevo_gtr5541 gotta remember the barras haven't seen near the amount of aftermarket development time and effort the RB and JZ have, but great strides are being made and we will see one meeting or exceeding their max hp number one day as they are just as capable. The cars they were attached to doesn't do the engine any favours either lol.
I am glad you mentioned the block castings and bore thickness because the 2jz is absolutely beautiful in that regard. In fact, aside from the stock head ports, the casting is all around better and boasts better head cooling and oil flow. You mentioned the shortcomings of the r32 oil pump, but you neglected to mention that the rb head fails to sufficiently drain the oil out of the head requiring you to port the drain holes and add larger head studs. Often times, people will "fix" the rb's oiling issues with an aftermarket oil pump, often increasing oil pressure and making the head draining issue worse. Even with the stock pump high rpm for extended periods of time can be catastrophic. Also, I find it a bit unfair to even compare it to the Supra, the Skyline chassis is hands down better in every single way. I really like the rb, particularly the rb30, and I love its sound, but to me the 2jz just seems like the "nicer" of the two. But of course if I am going to choose between a Skyline and a Supra I am going to take the Skyline.
The oil drain issue is as a result of high g forces during forward acceleration so on a circuit it shouldnt be as bad especially if the car had a dry sump system creating vacuum in the crankcase and making the head draining issue worse with an aftermarket pump is user error it means you failed to fit a restrictor to the oil feed on the block. He also didnt mention the 2jz habit of launching the harmonic balancer out the bonnet
Well said, but not only are the head oil drains insufficient but you also need to restrict oil going to the head in the first place to completely solve the problem
@@911lilslim the 2jz does no 'launch balancers out the bonet' they have a standard rev limiter of 6800 non vvti and 7200 for the vvti. If you are taking the car to 8000rpm's or higher youd be stupid not to upgrade the balancer which after 20 years can fail, just like the rb26's balancer. I rev mine to 9500rpm with a fluid damper for over 9 years now with no issues.
Warning: replacing the super obvious yellow marked hose will void your warranty and generate more power. Reminds me of the wine, erm grape juice concentrate bricks, sold in the US during prohibition. They displayed the warning: After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.
i think most of us can agree that the R32 was really ahead of its time, its really a work of art and its been my fav car ever since i saw it when i was younger
the Godzilla (the R32 BECAUSE THE OTHERS INCLUDING THE R34 ARE NOT THE REAL GODZILLA), the NSX, The Lan Evo's and Subaru Impresa are the only Japanese cars from the 90s that deserve their ""legend"" status... Because these demonstrated their potential in "racing" and they are not just cars that many love for tuning or movies... **wink, wink** you know which "movies and cars" I'm talking about! 💪🏻 PS: the NSX, although as a "car it doesn't win races", this car itself was created with the mentality of showing Ferrari and the rest of the Japanese brands that they were the "greatest" at that time. With the help of Mclaren they achieved many victories in F1 as a constructor.... In addition, the NSX also received advice from the Great Ayrton Senna!🗣️
I've always felt like the RB was more refined while the 2jZ was more brute force. All in all, I don't get the competition. They're both amazing legendary engines.
I think you have it backwards, Toyota actually looked at the rb and all their downfalls and used that to develop the 2jz (this was a rumor I’ve read on the forums so take that for what it’s worth). The 2jz has a more robust crankshaft, oil pump, oil pump spline, bigger bearings, non interference engine, better oil design and ports etc. The rb seems to be more of a brute force design for racing but with much more cons.
Of course the RB vs 2J battle will go on till people forget both engines ever existed. When I decided on swapping the 13B out of my FC Rx-7 for an inline 6 the reasons you mentioned lead me to an RB26 as the engine of choice. Nothing against 2J's, I looked at 1J's too since they're unarguably great engines, I just didn't need that much strength for a street application. Always loved higher reving engines and the sound of an RB26 just can't be beat.
I didn't realize you could FIT a non-rotary in an FC! As much as I loved my 2JZ, I don't think I'd do the swap you suggest. Just seems wrong to put a non-rotary in! In fact, I keep dreaming of a MX-5 with a 13B, maybe with an extra rotor...
@@lqr824 I hear people saying it seems wrong to put in a non-rotary into a rotary chassis car all the time but hear me out, I've owned 4 rotary cars, 2 FC turbos, 1 FC NA and later turbo converted and 1 Rx-8 and only owned 2 piston cars in my life, this will be the 3rd. Like anything if you experience it all the time it gets old and the mounts for the 13BT are still there, ready for the original engine. it's easier for me to make storage space for an engine rather than a whole other car so I decided on a swap. Maybe later on I'll get a skyline and swap the 13BT into that for kicks!
@@Dollsofgod Wow, that's a great story! Obviously these are very cool technical projects and you've got my total respect on that. My point is mostly that I'm just very conservative for some reason. I don't like the Corvette name on a mid-engine car for instance, don't like the V8 BMW M3's, and so on. I really have total respect for Mazda's rotaries, and obviously you like them too, so we're in agreement there!
It’s been long time accepted that rb stands for ‘ruined bearings’ because of its oiling issues. As a jz and rb owner, jz is overall better built, has less overall issues.
Actually... I’m fairly certain the “B” part in “RB” stands for the German word for benzene (“benzin”), which ultimately denoted that the engine is petrol powered.... since there is an “RD” engine too which has a D for “Diesel”. Nissan did the same thing to denote the difference with their Patrol motors... e.g. “TB42” for the petrols and “TD42” for the diesel variants. Both of the engine blocks for the RB/RD and the TB/TD are the same block with minor alterations depending on what fuel type it was going to be used for.
@@mrman8856 um nup Asian didn't say Gasoline they say Benzine so there's a possibility, but to be fair it might be or might be not, and lately Nissan ain't use that kinda code anymore so it's mystery
Nice Video! For your next versus video I would love to see a comparison between the RB25 and the 1JZ. I think this one would be more interesting because they are both 2.5L single turbo monsters. Plus in a way they are more affordable step down versions of these ones.
I have very stupid question. Where are you from? You have the clearest English I've ever heard and as non-native speaker I really appreciate it in your awesome educative vids. It makes it very easy to understand.
Im a hard core Toyota guy and while jz's are not my favorite (I prefer older Toyota engines) I can't deny that your logic and the perimeters you set do make sense and that you are right. Good video!
Great stuff! In addition to not having RB's in the US, there's another reason I prefer the 2JZ engine. Engine swaps are made easier with the exhaust on the right side. In right hand drive countries like Japan, I can see where the RB would have the advantage with its turbos on the left side.
I am not a horsepower freak - I put an essentially stock RB20 in my 1984 RX-7, and the 212-215 horsepower is perfect for daily driving. With the left hand drive I just wanted to mention that the RB motors are tilted to the left, and we reduced the tilt slightly to get clearance from the turbo to the steering gearbox.
@@benharrison2391 Huh, what a coincidence! I also have an 84 RX-7 but mine has a 350hp S5 13BT I installed about 15 years ago. Its crazy fast on-boost but still tame and calm enough to drive every day and it still passes CA smog. My N/A 2JZ is actually installed in a 59 Studebaker Lark......seems like a nutty idea, but it was originally a 6-cylinder car and only weighs 2600lbs, about the same as the RX-7..... so 220hp or so should work just fine once I finish the project!
@@84gssteveI am not allowed to reference my website here, but I am known as Stilettoman, and there is a TH-cam video showing my Skyline powered 48 Studebaker and the 84 RX-7. The Rx-7 is red and silver.
@@alstound Supras, and all 2JZ engines have their exhaust on the right which makes clearing the steering gear easier when swapping engines on a left hand drive vehicle. Another plus to the 2JZ is that it sits perfectly upright, instead of being canted over to one side. While this makes the engine taller, it also means that working on either side of the engine is easier.
One needs to be significantly richer to own an RB than a JZ. RB are great engines but come with serious flaws that require to be corrected before trying to do something. The RB bad habits to pump all the oil up into the head and let the crankshaft die by oil starvation is one of such flaws. The JZ are straight forward in comparison, even if they are born farther from the race track.
"Serious flaws" sounds like someone who lives on youtube/google. The average person with a tuned rb won't ever see these "flaws". Not everyone is on TH-cam running 1000kw and needs to worry about all these "oiling" system issue's. Yes, Rb do blow up, like any engine. Especially when its 31year old r32 that's imported with a wound back odo and been thrashed harder than you can imagine, with the rare oil change. I have been running rb's hard at over 350awkw for 15 years
@@shortybj40 a friend of mine is still owning his RB powered 700hp r33 (could theoretically hold 900+) and we went through these flaws. When he started to heard the engine knocking it was already too late, when opened the hood there was massive quantity of oil that had leaved the engine through oil catch tank, the car was oily to the rear axle. When he opened the crankcase he found the crankshaft was marked. He has been lucky enough to find another engine for a great price. Then he decided to rebuild that second engine to restart from a good basis, using forged internals to hold future big power setups and improve oiling system. Then he made a mistake about valves clearance which led him to re-open the engine to replace valves (heat expansion led valves-pistons contact). Now the car and its RB power plant are really great, it just cost much money to get that nice result.
So he ran 700hp on standard internals, it blew up. Then the engine was built incorrectly and not clearanced properly, and you still blame the type of engine
@@shortybj40 not at all, it outputs 700hp now with every work properly done, both to correct oiling system, and to mount reinforced/forged performance parts in it. The issue that killed the crankshaft occurred on stock configuration. You keep trying to make me say what I didn't say. In my opinion RBs are among best performance engines but they are a bit tricky and that require at least some additional work and money to get out of risk.
Love your video's, always more informative than usual TH-cam video's. To be honest I would love it if you can do an iconic engine video on the Volkswagen VR6 (2.8L 12v, 3.2L 24v and the 3.6L 24v) one of my favourite engines not because of its lack of power but the engineering aspect to fit a "V6" in a FWD hatchback.
If you like V6's in FWD cars you should check out the Mazda KLZE / KLDE V6 engines. They are 60*, DOHC, and they fit in some pretty small engine bays. The sound is right up there with Busso's and VR6's. 7500 rpm, aluminum, forged crank in cradle, weight of a 4 cyl.
Well, they kinda do... modern turbo engines can pretty easily be tweaked for more power, they just can't do it from the factory because of emissions and economy goals...
I was waiting for you to talk about the RB26 since you did the video on the 2JZ, and yes I agree with you that 500hp is more than enough to enjoy it's beauty
Please make a video about the OM606. It´s the diesel equivalent of the 2JZ. It can produce with stock Internals and a mechanical injectionpump 600HP. Besides it sounds awesome.
A great overview of the two engines. I feel like a few additions are worth putting in a comment. Firstly, as another commenter mentioned, the RB suffers from poor oil drain to the head. Generally it requires a restrictor (to limit oil flow to the head) as well as external drains. The second thing worth noting is that the RB has a far wider range of engines than the Toyota JZ. The JZ comes in 1JZ (2.5L) and 2JZ (3.0L) variants. The RB came in RB20, RB25, RB26, RB30, and even a rare and unusual RB24 variant. A lot of these were fitted to more standard production saloons rather than the firebreathing GTR. That said, by and large these motors can also be tuned very successfully, and so 'back in the day' the RB was a lot more accessible and familiar to tuners generally speaking. Of course nowadays, most RB-powered cars have been crashed, thrashed or trashed, so it's a different story!
The 2jz can basically be seen as a 3S-G extended by two cylinders. Same technology and same era; would also explain how it’s so strong, since the 503E race engine was basically the 3S before it was sold as the 3S
With racing history and stock for stock, the RB26 definitely shines and is a class above. I didn't know about the Supra race history NOT using the 2JZ. Wow! Though, 2JZ is also a great motor. Great video, sir!
Work on both, then make this video again. The 2JZ couldn't race because of displacement regulations in Japan. The RB is great and all. But the brutal simplicity, reliability and consistency of the 2JZ cannot be beat. It uses way more commonly available parts and less of the factory parts need to be changed to maintain a reliable 400 to 600whp car. The RB has chronic deal breaking issues with oiling and cooling regardless of the generation, the 2JZ just doesn't have those problems. It's always funny to hear the opinions of people who have clearly never built or worked on either engine. 2JZ for the win. Always.
The JTC-1 class, also known as Division 1, was eligible for cars with displacements of 2,501 cc or higher. Between 1985 and 1987 it was known as Division 3. So before you start coming up here with all that nonsense about the displacement regulations how about instead of assuming that your correct even after someone did their research, and not just a light skim through but a respectable amount of information. Then and only then will you have the right to comment about a topic instead of making yourself look like a fool.
@@d4a the RB is a totaly hopelessly bad engine block, it realy has not much going for it, ESPECIALLY compared to a 2JZ Again, i dare you to spend alittle bit of your time to simply look at motive's breakdown on the subject th-cam.com/video/FHSvVIkxPB4/w-d-xo.html
Great video! I was always under the impression the 2JZ is the better engine because it's stronger and never really cared too much about the RB. This video changed that. (I didn't change that I can't afford either engine tho lol). But I also have some questions left: 1. ITBs are awesome but are they that important in a boosted engine? Since the engine makes all the relevant power and torque under boost, ITBs seem to not have a great effect. Wouldn't pulses from the engine's intake side that would interfere and therefore reduce air flow in an N/A engine be mitigated by the positive pressure in the intake manifold anyways? 2. You showed that the RB makes peak power close to redline and peak torque 400rpms later than the 2JZ. This is of course due to the nature of these engines and makes the 2JZ's redline lower. I don't think this is a disadvantage tho. In some suítuations high revving has advantages, in others high torque does. Comes down to track and driving style I guess. I think both engines are great. Speed Academy are building a response Supra right now. I'm excited to see how a response tuned 2JZ handles.
On the topic of ITBs with turbos. Yes they absolutely are important. If you look at turbo racing engines from big money racing teams, the only reason that they aren't used are either : 1) Not allowed by regulations; BTCC, Rallycross and WRC 2) Cost reduction; GT3 cars, LMP2 and LMP3
I usually take the diplomatic approach but this time I wanted to offer a different perspective and provoke a bit as I feel some important things were obscured by others. There is no such thing as a superior engine, only a superior engine at a particular application, and the 2jz is, on average, only superior at ridiculous power applications.
@@d4a I was dead wrong. I think you’re really arguing what I think most RB fans are arguing. The Skyline GT-R is a much better platform for racing despite the 2JZ-GTE being the superior engine. I would agree with this statement. (By “superior” I mean .4 liters of increased displacement, a stronger block, better oiling system and a more simplistic design allows the 2JZ-GTE to do what it does at lower RPMs, with less stress and less chance for mechanical failure.) Great video, as usual, BTW.
@@quinty26 Hey Pal, You just blow in from stupid town? One Name Smokey Nagata! Remember that Supra that he took to England Yeah he swapped an RB into it.
Incredible video! Loved every second of it and your knowledge was refreshingly thorough! While overall I agree with your assessment I'd say your final conclusion that the RB26>2JZ isn't as clear cut of an argument but you did a better job of arguing R32>Supra. Both engines have their positives and negatives but the racing pedigree of the R32 is what sets it apart.
The more time passes by the more privileged I feel to own a piece of Motorsport history and this segment really hits home that fact. Long live the RB26 😍
I was really surprised to see that animation 10:57 in your video while watching it on my lunch break! I'm glad you used it :) Best regards, and keep making those thoroughly researched videos !!
Really enjoy your videos. Wondering if you might consider covering SAAB's B235 engine in your iconic engines? Another generation is fine, but I had two SAAB 95's that I really miss, and I've read the 95 had a better 60-90 time than a Porsche 911. Maybe this motor wasn't much in the racing and tuning world enough for the "iconic engines" series, but I've always felt SAAB was a very unique company and always did things their own way and outside of the box.
Thank you for this. Always loved the 2JZ but the RB was the engine I first fell in love with. Always sad it gets swept under the rug in so many conversations..... Also. 10 out of 10 ending.
@@Tkcb2799 platinum Motorsport have done LOTS of videos on the rb, and comparing hardness to a jz, which it got pissed on heavily. Also lacks deck thickness and material between bores.
but it begs the question why we haven’t seen 2j powered time attack cars. In contrast we have lots of RB powered cars. If a 2J is lighter and more robust than the RB, then we should see it more on track oriented builds…. right?
People here don't know the meaning of the phrase GT-Grand Tour, it is a type of car that is superbly reliable with a lot of power (Supra wiht 2jz), while sports car can afford to be less concerned with reliability and more with overall performance. And I would say it is unfair to say Nissan did a bad job with engine block QC or construction, they had a goal and a budget, and most of that budget went to amazing 4 wheel drive/steer system and chassis.
A Grand Tourer has nothing to do with reliability lol, where do you people come up with these things? There's no car class where reliability is a deciding factor for fitting in. A GT car is supposed to be comfy and powerful, like most non-track-focused Aston Martins. That's it.
Say what you want, but the 1JZ is the most beautiful sounding engine I've ever heard. Yes I do realize you are talking about the 2JZ :D Regardless, incredible content as usual! I'm learning so much through you boost school series!
As soon as you mentioned Australia, I wondered why you are not also discussing Ozs' own i6 Barra - think, 2jz bigger and better brother. I went to roll races a month ago, and there were mostly Barra and LS powered vehicles, and I think maybe one RB30, one RB26 and one 2JZ. Many many Barras and LS cars. Odd. Not to mention that it seems like every Nissan Patrol with a dead engine is being converteed to a Barra here in Oz. The Barra factory cast block and head can make >2500 crank hp. The 2jz factory block can make 1800hp (max) before the deck warps. The RB26 factory block can make what hp repeatably without falling apart ? I couldnt find this info, but, not many people are pushing the factory RB26 block beyond 1000hp it seems due to cracks around the head studs. Maybe some one here can educate me on factory cast RB26 blocks.
RB has a design flaw that limits stock blocks to around 1500hp ,Jz factory blocks have been pushed beyond 2000hp and Barra have another design flaw which limits them to 1700hp before but it's more of a displacement problem than a physical part problem
1GZ is basically two 1JZs put together with a modified bore and stroke. One guy literally put two 1JZs together to make a V12, you can look it up on youtube. No one has made a V12 RB yet though.
I have been waiting for you to do ,ore videos like this. As a man of culture and zero education I love explanatory videos from people who actually know a thing or two on the topic
I learnt a great deal here although I found your comparison wasn't really engine to engine. You compared the GTR series of vehicles to the 2JZ engine. The GTR chassis were all superior to the Supra. I don't think anyone can argue with that, but its a stretch to say that the RB engine is better without heavy aftermarket intervention.
I'm a Toyota fan but I've got admit you made the right Choice with the rb26. But I do have a problem with yardstick you use to compare the two. You pretty much used racing victories in which the 2JZ didn't even compete. I realize this is your point but it's also my point. Keep the great videos coming.
The yard stick was the touring races both cars were designed for and the manufacturer saw it fit to not use that engine to give themselves an advantage. The 2jz was built as a work horse thats why its in so many toyotas
I agree with your point about power range between 400 to 500 hp for the RB is more "suitable". Because for me, balance and driveabilty of engine and car is a way i will enjoy driving and have a largest smile/galon value. Gigantic horsepower is impressive, sure it is. But, i prefer to car that very enjoyable and balance rather than monster power, that eventually would kill myself when it is unattended
Wait, isn't considering motorsport as an argument in favor of the RB not the same as dismissing the 2jz for its racing accomplishments on the dragstrip or whatever? Both are equal to the metaphor of holding 5k rpm in the desert. I used to lean over to the RB as well, before I watched SA's 2jz and RB26 rebuilds/ refreshes. The RB is an absolute mess in pretty much all aspects of maintenance and ease of working on it, coupled with its inherent issues with oil pumps, oil starving and oil pan issues... Not to mention that the ITBs on the RB are pretty much a gimmick, only there for homologation and more often than not removed. ITBs have extremely little benefits in boosted applications.
Then we have the exploding cost difference. A 2JZ is still an affordable engine, a lowly RB20 will fetch over $3k now. Skylines should keep their RBs, but any other project, the 2JZ is the I6 of choice.
I am 100% not a drag racing guy, but there is a thousand reasons to choose the 2JZ over the RB26. To start with the 2JZ is lighter than the RB26. In stock form the 2jz makes more power, more torque and doesn't suffer from any issues. Where as you can't go around a hard corner with the RB26 without it dropping oil pressure. Not only does it drop oil pressure but if you keep the revs too high for too long you will go into starvation and destroy the bearings. The RB26 stock turbos can only handle 15psi before they explode, where as the 2JZ turbos are good for 23 + psi and 350 + kilowatts atw. The only thing stopping at 2JZ from revving to 9500+ RPM is the fact that you want shimless buckets after 9000rpm. RB26s have a range of problems over 8500 RPM. And these are just the issues with the stock engine, hardly a race engine. Anyone who is putting a small single turbo on to either of these engines is going to push upwards of 500 hp, which the RB26 cannot reliability achieve. Which means a lightly modified car needs a $25,000 built engine, where as you can have a race car or track car with a stock bottom end 2JZ which will last you many years. Issues the RB26 has that the 2JZ does not. Oil draining issues, oil pump issues, crank sensing issues, poor crank resolution, weak coilpack setup, no variable valve timing, thin bore walls, weak block construction, small headstuds, small oil drains from the head, weak turbos, noisy lifters and just a poor head cam setup to begin with. Less capacity due to shorter stroke but still cant rev as high? Yeah the RB26 is more comparable to the 1JZ but still not as good.
Honestly this whole which is better is annoying because by the time you spend 20k on a RB30/26 with all the fancy parts you can literally buy a race engine or billet block hahaha. 2jz or 1jz far better at cost to gain and like you said 10kg lighter and basically no trigger setups needed to make it big. And the material of the block is far far better and stronger.
Just to point out the JGTC rb26s were not stock, and the wins are mostly attributed to the amazing AWD system of the GTRs and not really the motors a bit unfair how you put one type of racing above another, just how hp handling characteristics is a small part of the overall package so is racing history. also you compared JDM 2jz's and not the export 2jz's which had bigger steel turbos vs smaller ceramic ones, bigger injectors, higher lift more duration cams and a fuel pump strong enough to support 550whp on pump gas. Export models also had better ecus and used a maf/map combo while jdm 2jz only had MAP sensors. export supras with a piggy back ecu,boost controller, bigger intercooler, downpipe and full exhaust have dynoed 420-480whp. the 2jz has a thicker deck height so has less block to cylinder head distortion under high cylinder pressure. Rbs have a slight problem with oil draining back into the sump and water/oil pump limitations (N1 or Nitto pumps solve this) you can shim OEM supra oil pump for higher pressures relatively easy and remove the sharp edges in the oil passages and that's all you need for reliable oil pressure and volume on a wet sump 2j (modded oil pumps are half the price of aftermarket rb ones). Shim under bucket and Shimless buckets are huge plus on very high revving motors especially when using high lift cams, but lets face it, if you are gonna swap out cams you're gonna have to get new buckets to set correct valve lash so the all toyota OEM shimless bucket conversion would be included then, as its not necessary for the OEM cam profile.
Could you also do a video on what oil to choose for a rotary engine? I'm afraid this topic won't blow the whole comment section to full scale flamewar yet.
Your a brave man making a video saying the 2jz engine wasn’t as good as the rb 😂😂.I personally prefer the rb as well. As soon as i spotted this video i thought to myself “oh jeez -let the nasty comments commence”. Brilliant video and very informative 👌
I'm probably going to make some petrol heads boil, but now since we talked about two of the best 6 cyl petrol engines ( BMW S54B32 would have been a great 3rd here to compare), what about the best 6 pot diesel ever made, aka Mercedes OM606, and the unreal power this thing can withstand?
@@85CEKR i guess its a matter of perspective really. im personally only familiar with the heavy duty Mercedes diesels in the freightliner not the passenger car diesels so i cant really comment on that. i personally like the Detroit 60 series the best out of all heavy duty diesels a old mac out of like a B series would be a close second. but if you're talking light duty pickups aka 1 and 3/4 ton and cars the 24 valve P pump is almost impossible to bet.
@@konnerkramer329 my dad had a Ram with the 12v for almost 20 years. It was a really cool truck and the engine was great. I just always think of those as truck engines and not really great for much else. I don't know alot about the specific Mercedes mentioned but I know Mercedes and BMW have made some pretty awesome straight 6 diesels over the years.
@@matthewbim10 define better. I can build a lighter engine that's easier to package to make whatever power level I'd like, for less money. I hate to say it, because I genuinely dislike a bunch of the people who own them, but the LS is just as capable up to the 2000hp mark. Weighs substantially less and costs A LOT less to build than an RB or JZ. And if I wanted more than that I could build a boosted big block and beat all 3 for less than the cost of the equivalent inline 6.
agreed. i scrolled down pretty far to then just reach skyline v supra fanboys duking it out. personally, 2jz for a insane drag build, rb for drift or track car. both are fantastic and amazing feats. we need more ppl like you who ackowledge both sides
Great review! I clearly recall all the V8 lovers going ape-s**t when this R-32 won Bathurst over the GM-H & Ford dinosaurs. I'd loved turbos since Renault in F1 and had been waiting for something like this to turn up after the turbo Saab effort, though a turbo Saab with the waste-gate held closed was also an interesting drive @ 17psi! Mechanics are always responsible with other peoples cars but I never said that. I later owned an RB30 powered Nissan Skyline R31 (yes, it was a station wagon and auto, but what a sleeper, it looked just like the 4cyl 2.0litre powered Aussie Pintara) but even as a turbo lover, this Australian only (?) engine was fabulous, even with only a SOHC head. I often dreamt of putting an RB26 head on it. Prior to owning this I had an earlier opportunity to road-test a stock GM-Holden RB30 turbo powered auto sedan when I worked at Fisherman's Bend, OMG, no wonder the V8 nearly died in Australia. If the Aussie dollar had NOT died around this time we may still have GM-H making the world's best all-round cars in production still. Much later as I drove to vehicle breakdowns in my normal flat-footed take-off style in my 3.2litre V6 dual-fuel (LPG or petrol) powered auto GM-H (Isuzu) bright yellow work ute, 1 night I encountered 2 modified Skylines heading east to enjoy the nearby Dandenong Ranges, a common cruising locale. At 3 sets of traffic lights in a row it was me on the left with these Skylines in the other 2 lanes, all front row. All 3 intersections were crossed by the ute first before being blitzed from then on before the next light went red to start all over again. They clearly thought I was racing them but I was just using someone else's fuel and car to make as much money as possible in each 12 hour shift. R32s are great but still need a driver who can drive or anticipate the 'Christmas Tree'. Perhaps the old adage of throwing 200kilos into the back of a ute to make is get traction helped, even over Godzillas. Practicing take-off reaction timing so often also couldn't have hurt!
Good thing dislikes are hidden so I can’t see if the community agrees or disagrees with the core message of the video/claim in the tittle, thanks Susan Jetski.
In my eyes, 2jz is better for high power aplications, as well as more reliable. RB wins in pretty much everything else. More rev happy and lighter means, it´s better if you are planning on building race car. Also, you can get V cam system from HKS and basically make it V-tec I6 we have never gotten.
The V cam system is just a variable intake cam timing system. It’s like the RB25 NEO heads from the gtst r33s and r34s. No variable lift, so it isn’t actually vtec
I think in the world of engine swaps, and the reason people may like a 2JZ is very simply, availability. You have 1 car and model to find a RB26, there are several vehicles running a 2jz. This is the same reason the LS series of engines are so popular. Easy to find, easy to build, and until recently for the 2jz, cheap to build.

Nice to see RB video. I asqed for it last video. And i have been w8ting more then half a year.
I think I have some "normal" schizophrenia about this video, because I love both the Nissans and the Toyotas (JDM alert😁). For that I have a MK3 MR2 being restored (maybe turbocharged?🤔) and a 350z used as a daily. Therefore I can't wait to see your upcoming videos (maybe about the VQ...😜).
But can't agree with your more. I'd take a Skyline over a Supra just because of the driveability. If I'd want straight line power, I'd go for an LS or a Hemi.
Keep up the good work mate, can't wait to see your turboed mk1 firing up😉.
can you do the om606 next?
Can you do the bmw s50 engine
just promoting products. and AEM in that regard is ok. but there are much better options out there. So no RB is not better , and the AEM is a poor choice as well. really bad video man. honestly saying. loved your videos before. but you kind of went to a level where you don't have the experience , and just make you look dumb.
"Epic Rap Battles of History!!!!! RB26 vs 2JZZZZZ!" lol. Thanks for your perspective on that and again much appreciate all the effort going into this
I’d say I’ll take both of them but I prefer 2jz for straight up power and less reliability (with power, that is) vice versa for rb26
You hafto say this with the voice 😂
@@vex9701 I've always been an RB26 fan ever since my first year of highschool, but I've always feared the 2J. Like bro i used to literally feel anxiety whenever i thought about the 2J. It just had so much damn power that it made me faulter at times when i watched RB videos. Those were scary times man.
So in conclusion, use the engine designed for your purposes. If you want an engine designed specifically for racing, use the engine designed for that. If you want the engine designed to survive anything (ie high horsepower) then use that. It really is a lesson to take into the wider world, in my opinion. Far too many people want to simplify things down to "x is better" or "you must do y" when there's always benefits and drawbacks for specific applications.

A really thoroughly researched comparison on these two engines, down here in Australia we absolutely love both of these engines, the RB in both drag racing and touring cars being very successful and the 2J predominantly in drag racing. We have a great after market support base for both engines, yet recently we are falling in love with our own locally designed in line 6 cylinder twin cam turbo engine, the Barra! We are seeing crazy numbers coming out of Barra engines on the dyno, thanks for the great video mate...
barras arent as good for racing until you destroke them, otherwise they just blow tires off, even my intech au lights tires quicker than my windsor au
The Barra is only good for one thing power and unusable torque, As it should its a 4L six that copied the head and port design of the 2j and RB. Good enough motor but they get too much credit for what they actually are. Once again a engine raved about because it can make power relatively easily. Fun fact no barra has ever beat the RB or 2J maximum hp number. lol
I dont want to upset Americans, Australians and the whole lot where drag racing is popular. But it's 10 seconds at .most. It's intense, it's fun but it's a humiliation to use a combustion engine for that, a combustion engine is overqualified for that job. I swear by god I can win that with a spring powered car or a water rocket shopping cart. It's only the designation as racing with rules that keeps the combustion engines still relevant in drag racing. Springs, catapults, electric motors, rockets, any other device is more qualified to discharge lots of power in a short time.
@@clevo_gtr5541 gotta remember the barras haven't seen near the amount of aftermarket development time and effort the RB and JZ have, but great strides are being made and we will see one meeting or exceeding their max hp number one day as they are just as capable. The cars they were attached to doesn't do the engine any favours either lol.
@@georgeyoutube7580 true, i think that people just like the Challenge
I am glad you mentioned the block castings and bore thickness because the 2jz is absolutely beautiful in that regard. In fact, aside from the stock head ports, the casting is all around better and boasts better head cooling and oil flow. You mentioned the shortcomings of the r32 oil pump, but you neglected to mention that the rb head fails to sufficiently drain the oil out of the head requiring you to port the drain holes and add larger head studs. Often times, people will "fix" the rb's oiling issues with an aftermarket oil pump, often increasing oil pressure and making the head draining issue worse. Even with the stock pump high rpm for extended periods of time can be catastrophic.
Also, I find it a bit unfair to even compare it to the Supra, the Skyline chassis is hands down better in every single way. I really like the rb, particularly the rb30, and I love its sound, but to me the 2jz just seems like the "nicer" of the two. But of course if I am going to choose between a Skyline and a Supra I am going to take the Skyline.
🤡😂
The oil drain issue is as a result of high g forces during forward acceleration so on a circuit it shouldnt be as bad especially if the car had a dry sump system creating vacuum in the crankcase and making the head draining issue worse with an aftermarket pump is user error it means you failed to fit a restrictor to the oil feed on the block. He also didnt mention the 2jz habit of launching the harmonic balancer out the bonnet
Well said, but not only are the head oil drains insufficient but you also need to restrict oil going to the head in the first place to completely solve the problem
@@911lilslim the 2jz does no 'launch balancers out the bonet' they have a standard rev limiter of 6800 non vvti and 7200 for the vvti. If you are taking the car to 8000rpm's or higher youd be stupid not to upgrade the balancer which after 20 years can fail, just like the rb26's balancer. I rev mine to 9500rpm with a fluid damper for over 9 years now with no issues.
he mentioned the poor piling in the head of the RB in another video.
Warning: replacing the super obvious yellow marked hose will void your warranty and generate more power.
Reminds me of the wine, erm grape juice concentrate bricks, sold in the US during prohibition.
They displayed the warning: After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.

ayyy oversimplified?
i think most of us can agree that the R32 was really ahead of its time, its really a work of art and its been my fav car ever since i saw it when i was younger
the Godzilla (the R32 BECAUSE THE OTHERS INCLUDING THE R34 ARE NOT THE REAL GODZILLA), the NSX, The Lan Evo's and Subaru Impresa are the only Japanese cars from the 90s that deserve their ""legend"" status...
Because these demonstrated their potential in "racing" and they are not just cars that many love for tuning or movies... **wink, wink** you know which "movies and cars"
I'm talking about! 💪🏻
PS: the NSX, although as a "car it doesn't win races", this car itself was created with the mentality of showing Ferrari and the rest of the Japanese brands that they were the "greatest" at that time. With the help of Mclaren they achieved many victories in F1 as a constructor.... In addition, the NSX also received advice from the Great Ayrton Senna!🗣️
I've always felt like the RB was more refined while the 2jZ was more brute force. All in all, I don't get the competition. They're both amazing legendary engines.
Can you sit a glass of 🍷 on a RB? NOPE! Lol
Mr Man, I think you’re thinking of the LS400, which has a 1UZ…
I think you have it backwards, Toyota actually looked at the rb and all their downfalls and used that to develop the 2jz (this was a rumor I’ve read on the forums so take that for what it’s worth). The 2jz has a more robust crankshaft, oil pump, oil pump spline, bigger bearings, non interference engine, better oil design and ports etc. The rb seems to be more of a brute force design for racing but with much more cons.
Of course the RB vs 2J battle will go on till people forget both engines ever existed. When I decided on swapping the 13B out of my FC Rx-7 for an inline 6 the reasons you mentioned lead me to an RB26 as the engine of choice. Nothing against 2J's, I looked at 1J's too since they're unarguably great engines, I just didn't need that much strength for a street application. Always loved higher reving engines and the sound of an RB26 just can't be beat.
I didn't realize you could FIT a non-rotary in an FC! As much as I loved my 2JZ, I don't think I'd do the swap you suggest. Just seems wrong to put a non-rotary in! In fact, I keep dreaming of a MX-5 with a 13B, maybe with an extra rotor...
@@lqr824 I hear people saying it seems wrong to put in a non-rotary into a rotary chassis car all the time but hear me out, I've owned 4 rotary cars, 2 FC turbos, 1 FC NA and later turbo converted and 1 Rx-8 and only owned 2 piston cars in my life, this will be the 3rd. Like anything if you experience it all the time it gets old and the mounts for the 13BT are still there, ready for the original engine. it's easier for me to make storage space for an engine rather than a whole other car so I decided on a swap. Maybe later on I'll get a skyline and swap the 13BT into that for kicks!
@@Dollsofgod Wow, that's a great story! Obviously these are very cool technical projects and you've got my total respect on that. My point is mostly that I'm just very conservative for some reason. I don't like the Corvette name on a mid-engine car for instance, don't like the V8 BMW M3's, and so on. I really have total respect for Mazda's rotaries, and obviously you like them too, so we're in agreement there!
The sheer amount of acronyms I learned in this video is more than the acronyms I learned in my whole life
Love the info & humor of this channel
It’s been long time accepted that rb stands for ‘ruined bearings’ because of its oiling issues.

Nope. The RB definitely stands for Rice Burner.

Mate barras are shit next to the jdm giants
Actually... I’m fairly certain the “B” part in “RB” stands for the German word for benzene (“benzin”), which ultimately denoted that the engine is petrol powered.... since there is an “RD” engine too which has a D for “Diesel”. Nissan did the same thing to denote the difference with their Patrol motors... e.g. “TB42” for the petrols and “TD42” for the diesel variants. Both of the engine blocks for the RB/RD and the TB/TD are the same block with minor alterations depending on what fuel type it was going to be used for.
Lol. You made up a whole fantasy!!! It has nothing to do with Germany at all! In reality it simple means RESPONSE BALANCE

Nice Video! For your next versus video I would love to see a comparison between the RB25 and the 1JZ. I think this one would be more interesting because they are both 2.5L single turbo monsters. Plus in a way they are more affordable step down versions of these ones.

Im a hard core Toyota guy and while jz's are not my favorite (I prefer older Toyota engines) I can't deny that your logic and the perimeters you set do make sense and that you are right. Good video!
Great stuff!
In addition to not having RB's in the US, there's another reason I prefer the 2JZ engine. Engine swaps are made easier with the exhaust on the right side. In right hand drive countries like Japan, I can see where the RB would have the advantage with its turbos on the left side.
I am not a horsepower freak - I put an essentially stock RB20 in my 1984 RX-7, and the 212-215 horsepower is perfect for daily driving. With the left hand drive I just wanted to mention that the RB motors are tilted to the left, and we reduced the tilt slightly to get clearance from the turbo to the steering gearbox.
@@benharrison2391
Huh, what a coincidence!
I also have an 84 RX-7 but mine has a 350hp S5 13BT I installed about 15 years ago. Its crazy fast on-boost but still tame and calm enough to drive every day and it still passes CA smog. My N/A 2JZ is actually installed in a 59 Studebaker Lark......seems like a nutty idea, but it was originally a 6-cylinder car and only weighs 2600lbs, about the same as the RX-7..... so 220hp or so should work just fine once I finish the project!
@@84gssteveI am not allowed to reference my website here, but I am known as Stilettoman, and there is a TH-cam video showing my Skyline powered 48 Studebaker and the 84 RX-7. The Rx-7 is red and silver.
Hmm, Mk4 Supras and Skylines have their exhausts on the left side like most German cars.
@@alstound Supras, and all 2JZ engines have their exhaust on the right which makes clearing the steering gear easier when swapping engines on a left hand drive vehicle. Another plus to the 2JZ is that it sits perfectly upright, instead of being canted over to one side. While this makes the engine taller, it also means that working on either side of the engine is easier.
One needs to be significantly richer to own an RB than a JZ.
RB are great engines but come with serious flaws that require to be corrected before trying to do something. The RB bad habits to pump all the oil up into the head and let the crankshaft die by oil starvation is one of such flaws.
The JZ are straight forward in comparison, even if they are born farther from the race track.
Price of admission has always been higher for jz, until covid times, now it’s all over the shop.
"Serious flaws" sounds like someone who lives on youtube/google. The average person with a tuned rb won't ever see these "flaws". Not everyone is on TH-cam running 1000kw and needs to worry about all these "oiling" system issue's. Yes, Rb do blow up, like any engine. Especially when its 31year old r32 that's imported with a wound back odo and been thrashed harder than you can imagine, with the rare oil change. I have been running rb's hard at over 350awkw for 15 years
@@shortybj40 a friend of mine is still owning his RB powered 700hp r33 (could theoretically hold 900+) and we went through these flaws.
When he started to heard the engine knocking it was already too late, when opened the hood there was massive quantity of oil that had leaved the engine through oil catch tank, the car was oily to the rear axle.
When he opened the crankcase he found the crankshaft was marked.
He has been lucky enough to find another engine for a great price.
Then he decided to rebuild that second engine to restart from a good basis, using forged internals to hold future big power setups and improve oiling system. Then he made a mistake about valves clearance which led him to re-open the engine to replace valves (heat expansion led valves-pistons contact).
Now the car and its RB power plant are really great, it just cost much money to get that nice result.
So he ran 700hp on standard internals, it blew up. Then the engine was built incorrectly and not clearanced properly, and you still blame the type of engine
@@shortybj40 not at all, it outputs 700hp now with every work properly done, both to correct oiling system, and to mount reinforced/forged performance parts in it.
The issue that killed the crankshaft occurred on stock configuration.
You keep trying to make me say what I didn't say.
In my opinion RBs are among best performance engines but they are a bit tricky and that require at least some additional work and money to get out of risk.
The rap is what got my thumbs up. Right before the end, nice! The whole video was informative though. I always like your stuff. Thank you.

He did cover the VR6 in one of his earlier videos.
If you like V6's in FWD cars you should check out the Mazda KLZE / KLDE V6 engines. They are 60*, DOHC, and they fit in some pretty small engine bays. The sound is right up there with Busso's and VR6's. 7500 rpm, aluminum, forged crank in cradle, weight of a 4 cyl.

I always preferred the RB26 over the 2JZ, but just because it sounds better lmao
A great overview of the two engines. I feel like a few additions are worth putting in a comment. Firstly, as another commenter mentioned, the RB suffers from poor oil drain to the head. Generally it requires a restrictor (to limit oil flow to the head) as well as external drains. The second thing worth noting is that the RB has a far wider range of engines than the Toyota JZ. The JZ comes in 1JZ (2.5L) and 2JZ (3.0L) variants. The RB came in RB20, RB25, RB26, RB30, and even a rare and unusual RB24 variant. A lot of these were fitted to more standard production saloons rather than the firebreathing GTR. That said, by and large these motors can also be tuned very successfully, and so 'back in the day' the RB was a lot more accessible and familiar to tuners generally speaking. Of course nowadays, most RB-powered cars have been crashed, thrashed or trashed, so it's a different story!
The 2jz can basically be seen as a 3S-G extended by two cylinders. Same technology and same era; would also explain how it’s so strong, since the 503E race engine was basically the 3S before it was sold as the 3S
Man, have you ever seen 3s block? Nothing near 503E.
All I care about is getting from Charleston SC to Vancouver BC and doing it as fast as I can!
As a man of culture, I recognize nissan made a legend.
With racing history and stock for stock, the RB26 definitely shines and is a class above. I didn't know about the Supra race history NOT using the 2JZ. Wow! Though, 2JZ is also a great motor. Great video, sir!
Only a true Rb fanboy could look past all the rbs downfalls and say its got nicer ports from factory so the rb is better xDD
I agree with you whole heartly!
The amount of people I tell that the Toms Castrol Supra didnt even have a 2jz in it and the look of horror 😂😂😂
Would love to see a video on gm’s 3800 3.8 L v6 engine
ah yes, AKA perfect Fiero swap
Me too. Very popular engine here in Aus.
Love the video. Having said that, the 4 wheel Drive system is the main reason why it was so dominant.
Work on both, then make this video again. The 2JZ couldn't race because of displacement regulations in Japan. The RB is great and all. But the brutal simplicity, reliability and consistency of the 2JZ cannot be beat. It uses way more commonly available parts and less of the factory parts need to be changed to maintain a reliable 400 to 600whp car. The RB has chronic deal breaking issues with oiling and cooling regardless of the generation, the 2JZ just doesn't have those problems. It's always funny to hear the opinions of people who have clearly never built or worked on either engine. 2JZ for the win. Always.
😂
The JTC-1 class, also known as Division 1, was eligible for cars with displacements of 2,501 cc or higher. Between 1985 and 1987 it was known as Division 3. So before you start coming up here with all that nonsense about the displacement regulations how about instead of assuming that your correct even after someone did their research, and not just a light skim through but a respectable amount of information. Then and only then will you have the right to comment about a topic instead of making yourself look like a fool.

Great video. I learned so much
good vid, was very comprehensive on the benefits of a RB26DETT.
Thanks for taking the time to put this vid together!
Great video! I was always under the impression the 2JZ is the better engine because it's stronger and never really cared too much about the RB. This video changed that. (I didn't change that I can't afford either engine tho lol).
But I also have some questions left:
1. ITBs are awesome but are they that important in a boosted engine? Since the engine makes all the relevant power and torque under boost, ITBs seem to not have a great effect. Wouldn't pulses from the engine's intake side that would interfere and therefore reduce air flow in an N/A engine be mitigated by the positive pressure in the intake manifold anyways?
2. You showed that the RB makes peak power close to redline and peak torque 400rpms later than the 2JZ. This is of course due to the nature of these engines and makes the 2JZ's redline lower. I don't think this is a disadvantage tho. In some suítuations high revving has advantages, in others high torque does. Comes down to track and driving style I guess.
I think both engines are great. Speed Academy are building a response Supra right now. I'm excited to see how a response tuned 2JZ handles.
There are other videos that proves that the 2jz is better, also the 2jz is way more popular/used in many applications compared to the rb

On the topic of ITBs with turbos. Yes they absolutely are important. If you look at turbo racing engines from big money racing teams, the only reason that they aren't used are either :

2) Cost reduction; GT3 cars, LMP2 and LMP3

Ok, I’m going to make the prediction that you take the diplomatic approach, but I think we all know which engine is superior. 😉
I usually take the diplomatic approach but this time I wanted to offer a different perspective and provoke a bit as I feel some important things were obscured by others. There is no such thing as a superior engine, only a superior engine at a particular application, and the 2jz is, on average, only superior at ridiculous power applications.

I was dead wrong. I think you’re really arguing what I think most RB fans are arguing. The Skyline GT-R is a much better platform for racing despite the 2JZ-GTE being the superior engine. I would agree with this statement.
(By “superior” I mean .4 liters of increased displacement, a stronger block, better oiling system and a more simplistic design allows the 2JZ-GTE to do what it does at lower RPMs, with less stress and less chance for mechanical failure.)
Great video, as usual, BTW.
@@d4a lol.....
@@d4a The 2JZ is more reliable. So, it actually is superior. Nobody swaps the RB26 engines, because they are prone to issues.
@@quinty26 Hey Pal, You just blow in from stupid town? One Name Smokey Nagata! Remember that Supra that he took to England Yeah he swapped an RB into it.
Me: I should sleep, I have school tomorrow.
Also me: Watches 23 minute video about engines I will never own.
Can you discuss the Toyota Celica VVTi vs Honda Integra VTEC engine?
you just simply love the rb engine as i conclude it
Incredible video! Loved every second of it and your knowledge was refreshingly thorough! While overall I agree with your assessment I'd say your final conclusion that the RB26>2JZ isn't as clear cut of an argument but you did a better job of arguing R32>Supra. Both engines have their positives and negatives but the racing pedigree of the R32 is what sets it apart.
The more time passes by the more privileged I feel to own a piece of Motorsport history and this segment really hits home that fact.
Long live the RB26 😍
I was really surprised to see that animation 10:57 in your video while watching it on my lunch break! I'm glad you used it :) Best regards, and keep making those thoroughly researched videos !!
Thank you for being so cool about it and thanks for watching. The animation is really nice, kudos
Really enjoy your videos. Wondering if you might consider covering SAAB's B235 engine in your iconic engines? Another generation is fine, but I had two SAAB 95's that I really miss, and I've read the 95 had a better 60-90 time than a Porsche 911. Maybe this motor wasn't much in the racing and tuning world enough for the "iconic engines" series, but I've always felt SAAB was a very unique company and always did things their own way and outside of the box.
Thank you for this. Always loved the 2JZ but the RB was the engine I first fell in love with. Always sad it gets swept under the rug in so many conversations..... Also. 10 out of 10 ending.
The hardest rb block has been found to be softer than the softest 2j.
Source?
@@Tkcb2799 platinum Motorsport have done LOTS of videos on the rb, and comparing hardness to a jz, which it got pissed on heavily. Also lacks deck thickness and material between bores.
Also 2j block is actually lighter than rb block.
but it begs the question why we haven’t seen 2j powered time attack cars. In contrast we have lots of RB powered cars. If a 2J is lighter and more robust than the RB, then we should see it more on track oriented builds…. right?
@@devandrasimanjuntak1646 They weighed the 2JZ compared to an RB30, not a 26 so maybe that´s where the difference is.
Thank you for yet another quality video.
The best Day of the week. Have a Nice evening.
amazing video man! always love how informative you are and how you can teach me something :)
THAT RAP...... has earned you a subscriber ;) RB all the way
People here don't know the meaning of the phrase GT-Grand Tour, it is a type of car that is superbly reliable with a lot of power (Supra wiht 2jz), while sports car can afford to be less concerned with reliability and more with overall performance.
And I would say it is unfair to say Nissan did a bad job with engine block QC or construction, they had a goal and a budget, and most of that budget went to amazing 4 wheel drive/steer system and chassis.
agreed. Imagine how fast and reliable the skyline would be with a 2J. :) Actually the 2J would make the 4 wheel drive system unreliable. lol
A Grand Tourer has nothing to do with reliability lol, where do you people come up with these things? There's no car class where reliability is a deciding factor for fitting in.
A GT car is supposed to be comfy and powerful, like most non-track-focused Aston Martins. That's it.
This is a great series. I will patiently await the Saab B202 video 0_0
Say what you want, but the 1JZ is the most beautiful sounding engine I've ever heard. Yes I do realize you are talking about the 2JZ :D Regardless, incredible content as usual! I'm learning so much through you boost school series!
Make a video on Ford's FE V8. No one ever pays attention to the giants of the 60's. The 427 side oiler, the 426 hemi, the 427 L88.
As soon as you mentioned Australia, I wondered why you are not also discussing Ozs' own i6 Barra - think, 2jz bigger and better brother.
I went to roll races a month ago, and there were mostly Barra and LS powered vehicles, and I think maybe one RB30, one RB26 and one 2JZ. Many many Barras and LS cars. Odd.
Not to mention that it seems like every Nissan Patrol with a dead engine is being converteed to a Barra here in Oz.
The Barra factory cast block and head can make >2500 crank hp. The 2jz factory block can make 1800hp (max) before the deck warps.
The RB26 factory block can make what hp repeatably without falling apart ? I couldnt find this info, but, not many people are pushing the factory RB26 block beyond 1000hp it seems due to cracks around the head studs. Maybe some one here can educate me on factory cast RB26 blocks.
Or BMW'S B32 i6
RB has a design flaw that limits stock blocks to around 1500hp ,Jz factory blocks have been pushed beyond 2000hp and Barra have another design flaw which limits them to 1700hp before but it's more of a displacement problem than a physical part problem
RB-26 the engine the myth the legend🙌
Speaking of inline 6 engines, a video on the legendary Mercedes Benz M103 + M104 engines would be epic👍🏻
D4A engine rap gets better and better .You`ll steal Ludacris's role in Fast&furious with those bars
Someone have to make a V12 with both Block's.
1GZ is kinda like two 1jz together
My self prefer to have a M104 it has 3.2 L 24V capital of 1200hp and it's cost just 500-700 over here at Germany.
@E L in all honesty I didn't know the m30 existed.
1GZ is basically two 1JZs put together with a modified bore and stroke. One guy literally put two 1JZs together to make a V12, you can look it up on youtube. No one has made a V12 RB yet though.
@@inaNis_ A guy in France did.
I have been waiting for you to do ,ore videos like this. As a man of culture and zero education I love explanatory videos from people who actually know a thing or two on the topic
I learnt a great deal here although I found your comparison wasn't really engine to engine. You compared the GTR series of vehicles to the 2JZ engine. The GTR chassis were all superior to the Supra. I don't think anyone can argue with that, but its a stretch to say that the RB engine is better without heavy aftermarket intervention.
👏🏻👏🏻👏🏻👏🏻 you are absolutely right!
👍🏻👍🏻👍🏻👍🏻The ending rap is awesome!
I'm a Toyota fan but I've got admit you made the right Choice with the rb26. But I do have a problem with yardstick you use to compare the two. You pretty much used racing victories in which the 2JZ didn't even compete. I realize this is your point but it's also my point. Keep the great videos coming.
The yard stick was the touring races both cars were designed for and the manufacturer saw it fit to not use that engine to give themselves an advantage. The 2jz was built as a work horse thats why its in so many toyotas
thanks, i really enjoyed this, its very helpfull
I agree with your point about power range between 400 to 500 hp for the RB is more "suitable". Because for me, balance and driveabilty of engine and car is a way i will enjoy driving and have a largest smile/galon value.
Gigantic horsepower is impressive, sure it is. But, i prefer to car that very enjoyable and balance rather than monster power, that eventually would kill myself when it is unattended
It's convenient click bait. An rb needs work for 4-500hp, a stock 2j needs nothing. How does it make it the loser then?
@@Low760 is it became a problem for you if i prefer to RB instead of JZ?
THANK YOU, finally someone with a proper opinion
"Hentai stickers on car ppl"
I'm so glad to see my people are represented!
One of my favourites to date! Rap was spot on too! Loved it🤙
Wait, isn't considering motorsport as an argument in favor of the RB not the same as dismissing the 2jz for its racing accomplishments on the dragstrip or whatever? Both are equal to the metaphor of holding 5k rpm in the desert.
I used to lean over to the RB as well, before I watched SA's 2jz and RB26 rebuilds/ refreshes. The RB is an absolute mess in pretty much all aspects of maintenance and ease of working on it, coupled with its inherent issues with oil pumps, oil starving and oil pan issues... Not to mention that the ITBs on the RB are pretty much a gimmick, only there for homologation and more often than not removed. ITBs have extremely little benefits in boosted applications.
Then we have the exploding cost difference. A 2JZ is still an affordable engine, a lowly RB20 will fetch over $3k now. Skylines should keep their RBs, but any other project, the 2JZ is the I6 of choice.
That first pie chart really says something about the car enthusiasts world
I am 100% not a drag racing guy, but there is a thousand reasons to choose the 2JZ over the RB26.
To start with the 2JZ is lighter than the RB26. In stock form the 2jz makes more power, more torque and doesn't suffer from any issues. Where as you can't go around a hard corner with the RB26 without it dropping oil pressure. Not only does it drop oil pressure but if you keep the revs too high for too long you will go into starvation and destroy the bearings. The RB26 stock turbos can only handle 15psi before they explode, where as the 2JZ turbos are good for 23 + psi and 350 + kilowatts atw.
The only thing stopping at 2JZ from revving to 9500+ RPM is the fact that you want shimless buckets after 9000rpm. RB26s have a range of problems over 8500 RPM. And these are just the issues with the stock engine, hardly a race engine.
Anyone who is putting a small single turbo on to either of these engines is going to push upwards of 500 hp, which the RB26 cannot reliability achieve. Which means a lightly modified car needs a $25,000 built engine, where as you can have a race car or track car with a stock bottom end 2JZ which will last you many years.
Issues the RB26 has that the 2JZ does not. Oil draining issues, oil pump issues, crank sensing issues, poor crank resolution, weak coilpack setup, no variable valve timing, thin bore walls, weak block construction, small headstuds, small oil drains from the head, weak turbos, noisy lifters and just a poor head cam setup to begin with. Less capacity due to shorter stroke but still cant rev as high? Yeah the RB26 is more comparable to the 1JZ but still not as good.
Honestly this whole which is better is annoying because by the time you spend 20k on a RB30/26 with all the fancy parts you can literally buy a race engine or billet block hahaha. 2jz or 1jz far better at cost to gain and like you said 10kg lighter and basically no trigger setups needed to make it big. And the material of the block is far far better and stronger.
RB has 12 mm head studs, 2jz 10mm. RB has stronger crank bed, beter cooling cause of bigger spacing.
@@glennandrews5103 still as a GTR fanboy, I'd get the Rb, at least it makes me happy
8:24 I yelled out "how boring!" and then you came right in with it
Just to point out the JGTC rb26s were not stock, and the wins are mostly attributed to the amazing AWD system of the GTRs and not really the motors a bit unfair how you put one type of racing above another, just how hp handling characteristics is a small part of the overall package so is racing history. also you compared JDM 2jz's and not the export 2jz's which had bigger steel turbos vs smaller ceramic ones, bigger injectors, higher lift more duration cams and a fuel pump strong enough to support 550whp on pump gas. Export models also had better ecus and used a maf/map combo while jdm 2jz only had MAP sensors. export supras with a piggy back ecu,boost controller, bigger intercooler, downpipe and full exhaust have dynoed 420-480whp. the 2jz has a thicker deck height so has less block to cylinder head distortion under high cylinder pressure. Rbs have a slight problem with oil draining back into the sump and water/oil pump limitations (N1 or Nitto pumps solve this) you can shim OEM supra oil pump for higher pressures relatively easy and remove the sharp edges in the oil passages and that's all you need for reliable oil pressure and volume on a wet sump 2j (modded oil pumps are half the price of aftermarket rb ones). Shim under bucket and Shimless buckets are huge plus on very high revving motors especially when using high lift cams, but lets face it, if you are gonna swap out cams you're gonna have to get new buckets to set correct valve lash so the all toyota OEM shimless bucket conversion would be included then, as its not necessary for the OEM cam profile.
Cringe part won my like :D great job m8 and keep up the good work
Could you also do a video on what oil to choose for a rotary engine? I'm afraid this topic won't blow the whole comment section to full scale flamewar yet.
Toss some 2 cycle lawn mower oil in with the gas and roll...the engine will thank you!
@@billyhess5263 Marine 2 stroke oil works as well.

Your a brave man making a video saying the 2jz engine wasn’t as good as the rb 😂😂.I personally prefer the rb as well. As soon as i spotted this video i thought to myself “oh jeez -let the nasty comments commence”. Brilliant video and very informative 👌
I'm probably going to make some petrol heads boil, but now since we talked about two of the best 6 cyl petrol engines ( BMW S54B32 would have been a great 3rd here to compare), what about the best 6 pot diesel ever made, aka Mercedes OM606, and the unreal power this thing can withstand?
best 6 cylinder diesel... Cummins might have something to say about that.
@@konnerkramer329 I'm a big fan of the Cummins, but I really don't think it's close to being the best six cylinder diesel all thing considered.
Why not the Barra ? The i6 Barra can make >2500hp on the factory cast block and head. A 2jz factory block 1800hp max before the deck warps.
@@85CEKR i guess its a matter of perspective really. im personally only familiar with the heavy duty Mercedes diesels in the freightliner not the passenger car diesels so i cant really comment on that. i personally like the Detroit 60 series the best out of all heavy duty diesels a old mac out of like a B series would be a close second. but if you're talking light duty pickups aka 1 and 3/4 ton and cars the 24 valve P pump is almost impossible to bet.
@@konnerkramer329 my dad had a Ram with the 12v for almost 20 years. It was a really cool truck and the engine was great. I just always think of those as truck engines and not really great for much else. I don't know alot about the specific Mercedes mentioned but I know Mercedes and BMW have made some pretty awesome straight 6 diesels over the years.
Before watching this I got so excited lol
They're both exceptional engines. And exceptionally overpriced on the used market lol.
Unless you want a new billet, good luck finding better ones for cheaper!
@@matthewbim10 define better. I can build a lighter engine that's easier to package to make whatever power level I'd like, for less money. I hate to say it, because I genuinely dislike a bunch of the people who own them, but the LS is just as capable up to the 2000hp mark. Weighs substantially less and costs A LOT less to build than an RB or JZ. And if I wanted more than that I could build a boosted big block and beat all 3 for less than the cost of the equivalent inline 6.
@@matthewbim10 ill name a few; Volvo White and Redblocks, Mercedes M103 M104, BMW M50/52, Ford Barra (atleast in australia)
agreed. i scrolled down pretty far to then just reach skyline v supra fanboys duking it out. personally, 2jz for a insane drag build, rb for drift or track car. both are fantastic and amazing feats. we need more ppl like you who ackowledge both sides
Great review! I clearly recall all the V8 lovers going ape-s**t when this R-32 won Bathurst over the GM-H & Ford dinosaurs. I'd loved turbos since Renault in F1 and had been waiting for something like this to turn up after the turbo Saab effort, though a turbo Saab with the waste-gate held closed was also an interesting drive @ 17psi! Mechanics are always responsible with other peoples cars but I never said that.
I later owned an RB30 powered Nissan Skyline R31 (yes, it was a station wagon and auto, but what a sleeper, it looked just like the 4cyl 2.0litre powered Aussie Pintara) but even as a turbo lover, this Australian only (?) engine was fabulous, even with only a SOHC head. I often dreamt of putting an RB26 head on it.
Prior to owning this I had an earlier opportunity to road-test a stock GM-Holden RB30 turbo powered auto sedan when I worked at Fisherman's Bend, OMG, no wonder the V8 nearly died in Australia. If the Aussie dollar had NOT died around this time we may still have GM-H making the world's best all-round cars in production still.
Much later as I drove to vehicle breakdowns in my normal flat-footed take-off style in my 3.2litre V6 dual-fuel (LPG or petrol) powered auto GM-H (Isuzu) bright yellow work ute, 1 night I encountered 2 modified Skylines heading east to enjoy the nearby Dandenong Ranges, a common cruising locale. At 3 sets of traffic lights in a row it was me on the left with these Skylines in the other 2 lanes, all front row. All 3 intersections were crossed by the ute first before being blitzed from then on before the next light went red to start all over again. They clearly thought I was racing them but I was just using someone else's fuel and car to make as much money as possible in each 12 hour shift. R32s are great but still need a driver who can drive or anticipate the 'Christmas Tree'.
Perhaps the old adage of throwing 200kilos into the back of a ute to make is get traction helped, even over Godzillas. Practicing take-off reaction timing so often also couldn't have hurt!
Good thing dislikes are hidden so I can’t see if the community agrees or disagrees with the core message of the video/claim in the tittle, thanks Susan Jetski.
"As a mand of culture" the lines like this are why I watch this Chanel over others that offer similar content.
In my eyes, 2jz is better for high power aplications, as well as more reliable.
RB wins in pretty much everything else. More rev happy and lighter means, it´s better if you are planning on building race car. Also, you can get V cam system from HKS and basically make it V-tec I6 we have never gotten.
Yep that's what I thought before clicking this video. There's a reason why TOM's Supra didn't use the 2JZ and instead used the 3S-GTE
The V cam system is just a variable intake cam timing system. It’s like the RB25 NEO heads from the gtst r33s and r34s. No variable lift, so it isn’t actually vtec
it's enough to have the NSX V6 first Vtec ever
@@Xayuap NSX V6 was kind of underwhelming compared to the nissan / toyota counterparts in tuning department.
@@RealLeskot do you think that an I6 vtec would do the trick?
Nice one as usual ! Waiting for the XU10 now ^^
I think in the world of engine swaps, and the reason people may like a 2JZ is very simply, availability. You have 1 car and model to find a RB26, there are several vehicles running a 2jz. This is the same reason the LS series of engines are so popular. Easy to find, easy to build, and until recently for the 2jz, cheap to build.
Enjoyed every second of that. Thankyou
The thing is I would rather listen to the people who work on and tune those engines. The 2JZ is king. Cool video though. Controversy is palatable.
Agreed. Here’s a real comparison of the 2 engines th-cam.com/video/FHSvVIkxPB4/w-d-xo.html
Very cool.....the rap👍
as a guy born and living in munich i would say i root for the N54, but between the RB26 and 2JZ i would choose the RB26
I didn't know the first winner of the jtcc was driving a 635csi.. thats awesome.
