RB25DET vs 1JZ-GTE - Engine Block Tests and Comparison
ฝัง
- เผยแพร่เมื่อ 14 ต.ค. 2024
- We did RB30 vs 2JZ engine block comparison, now its time to test and compare their little brothers. The RB25DET and the 1JZ-GTE engine blocks.
Please note, we are only testing the bare block, no other ancillary parts that go with it.
So much more respect for the Supra’s 1J/2JZ engine after watching these videos. They engineered the crap out of these engines, no wonder they’re so legendary.
yeah I am practically a fanboy of the JZ engines, but even I never realized how overengineered and well made these engines are. I knew they were good, but I didn't think they were *THIS* good, it absolutely blows my mind.

As an RB lover the stats break my heart 🤣
But we can't do anything about it... Uguu...
RB is the caterpillar
mate youre everywhere!
1JZ GTS...
If you want them to test a block.... strip one down and send it in🤣
would love to see the m50b25 comparison . its a well capable platform
+1
Meh, I'd say it's average at best. Still, I'd like to see it aswell. Mainly because literally every BMW guy here in Sweden says it's an amazing engine.
Euro block S50 too
@@theXbaT1 yeah Euro S50's are extremely reliable at high power, but they are so damn expensive to buy and build that no mortal man could afford it
@@TheProtagonistGabber
what on earth? s50 cost somethink like 2000-6000€. that is not that expensive. at least here in germany. on the other hand we definitly do not have a shortage on bmw blocks. they are fairly good. the real weakness are the connection rod bearings. you have to change those every 100k km. otherwise my e36 works perfectly fine, despite having 380bhp (airbox, cams, ecu).
It’s not just the blocks that make JZ king. They oil pumps are superior, the stock head gasket is damn near perfect, the heads are awesome un ported. List goes on
And the People that go 1.5jz... like them also.
thank you yamaha ;)
Dan MC we are looking at doing other comparisons later
We Kew it simple by just looking at one component at a time
@Lucky Rooster have to wait for that video
@@MotiveVideo People say the head on 2JZ-GE is designed better and has a better flow. There are many that go GE+Turbo instead of GTE
Can you guys do some 4 cylinder comparisons too like the 4G63 block Vs the 4B11 block or the SR block Vs the 3S-GTE etc? I've got an Evo 5 so would be great to see some testing done on the 4G63 block
Ej20 and ej25 have mixed reputations too. Probably been tested a hundred times before but I like the way these videos are presented
@@HaydenSupaTeeu cant compare a iron block to a alloy block, the only difference between ej20 and ej25 is the bore size and thickness and I can tell u the ej20 wins hands down
Scaniaman93 patience. We can only make so many videos in our spare time as we can
If we had a million subscribers we could make TH-cam videos every day
If you build it, they will come :)@@MotiveVideo
@@HaydenSupaTee why bother john cena 😂😂. Im such your a wrestler. You troll . Ej20 and sr20 are both rubbish
3S-GTE Gen 2/3 VS SR20 would’ve been very interesting too. :)
I would like to see the german S54 just out of curiosity.
you and me both
its alu so no go
TheXbaT no it ain't
Mercedes m104/103 om603/606?
@yba202 I didn't even know they were from australia this was the first video I saw
The 1JZ is 11 KG LIGHTER! With thicker bores too.
Yeah that's nuts.. Better quality steel I wonder?
@@mattfowles7239 Steel may be the same alloy. It's the control of the casting process that matters. The rapidity of the cooling rate of the block casting effects tensile strength. Faster cooling the better.
@@tumdeax You don't want faster cooling of a big casting, that introduces alot of inner stress that cab crack or change dimesions after machining.
Iron my dudes, it's iron. Not steel. Iron is porous, which means it retains oil nicely and stays lubricated. It's why it's good for blocks.
You guys are awesome with these Platinum Tech engine nit-picking series. No one else in the world does it
Oh damn... When you guys can get your hands on a B58 block you have to do another comparison! New Supra block vs old Supra block. Would blow up. Plus I'd love to see the information.
Thanks for the video and the objective numbers! One correction: the video says deck height, but I think deck thickness is meant. The deck height is the distance between the crank centerline and the top of the deck, essentially the block height. This is the main difference between a 1JZ block and a 2JZ block: the 2JZ block is the taller of the two.
Love my 1JZ 😍
Ditto bro. 👍
your production quality and information delivered have had a huge increase over the past year. and you collabs with nitto and PRP have deffinately helped with that. great job Motive!
Doing straight sixes might as well throw an N54 and N55 in there too :D
Loving this series, good to see the data
You need more subscribers Andrew. This channel is 20 times betters then half the american car channels going.
Nathan Lenehan thanks mate. We’re trying and putting more effort in now
@@MotiveVideo well its appreciated..by the Australian audience at least. Would actually been very keen on meeting you one day.
I’m glad I went with the 1jz in my r33 now thanks for the info been really enjoying the content
Yeh I went non vvti, did the same conversion in a mates s14 and it went well so I decided to do the same
Rb25 ten times better
@@kartaku132 did you just ignore the video while commenting this?
Im loving these series of videos. Its all facts and no bs.
Leave following these tech series. This is phenomenal. Thank you Andrew and crew. I'd like to request an answer to one of the biggest questions of today.....2JZ/1JZ vs B58 (BMW)...Hoping you can pull this test off in the near future.
I can't see enough of these - so interesting! Looking forward to seeing so many more of them with different engines...
Great video again guys. The 1JZ was designed by Yamaha for Toyota, as a replacement/upgrade to the M series Toyota six cylinder engines. The 7m gte which came in the JZA70 Supra was a great engine but suffered from overheating, head gasket and head stud issues where the head would tend to lift at high boost. As a die hard RB man, these videos are heartbreaking, but give credit where it's due, the JZ engines are monsters.
Yamaha only designed the 1jz head, not the block.
1jz engine values will now skyrocket
Debt and Regret your good at telling the future check the prices now lol
Just got mine today! With an R154!
I remember seeing this comment last year now their worth a million 😂
They actually did lol
a year later and they have....
To be honest, I would be more happy meeting these guys for example Herman than any other celebrities.🙌🏼
Thank you again guys. Would be good to see the merc engine m157 being analysed like this
"the internet has spoken". Oh well, it still speaks,....RB20!
Tom Ingvaldsen that has been filmed. We can only edit in our personal time so quickly
@@MotiveVideo Oh,....thats great👌 Thanks for these interesting and enlightening vids👍
1JZ could be the most underrated 6 of all time !
No m104.
7mgte bruh
@@chrisjay7736 Oh hell yeah. Love to see another Benz-knower
They're hardly underrated, they're idolised!
Barra
I knew that putting the 1JZGTE in the MK3 Supra was going to be Paramount. Again legendary in its own right!!!!
Would love to see an in depth video like this between the 1FZ-FE vs TB48!
I agree this channel is underrated. Every time I say to some one if they follow motive DVD and they seem clueless ! Spread the word 👌
Also be interested to see the BMW N55 platform seeing as it's basically a comparative block.
Great series, Herman knows his stuff.
Loving the vids guys great work. I would be interested to see how the 7mgte stacks up against the 2jz or rb30.
It doesn't, 7ms are an amazing boat anchor. 2jz is the younger stronger brother. Anyone who's built a 7m will tell you the dramas they've gone thru just to make them stay together.
@@TARMACULA these guys are testing the castings, im curious how 7m castings compare simple as that. 7ms are old tech so they have their quirks especially the early long blocks but i have been running a 400whp 7m for about 7 years no issues with little money spent. Im getting tired of proveing 7ms to dense internet people.
I´d like to see you explain what exactly you´re measuring, especially the hardness test, to me they´re just random numbers, the higher the better. Really interesting channel by the way, I´ve never seen anything like this, great work.
Could you do a whole video talking about thickness and hardness? By that of course I mean in terms of engine blocks! would be great if you would go more in depth about the tools you are using and what exactly the measurements mean. I would like to understand the values better from a technical perspective. I'm sure many other viewers would as well!
Awesome videos and thank you.
Wow!! Wasn't expecting that! That Supra engine! Is no Joke!
im a boilermaker with abit of age,and spent a lot of time in bhp.the meteorologist there new there stuff and was always cutting different car brands castings up,toyota was always good back then.im guessing herman knows exactly what im saying in metal count and grey power metal counts and acid tests and so on,there are still afew of the old boys around be good to get 1 on your show and get him to explain why things can be stronger but lighter and so on,from memory I think a yank did a lot of Toyotas early metal count mixs.be good vid for those that don't know.
As some people have already requested, I am sure at least your European and some American viewers will be highly interested in a comparison with the BMW M50 block. It is 84mm bore, 48kg and has 10mm head bolts, that is all I know after a quick search but how is the rest of the engine? Here in Europe we have those engines in tuner cars, drag cars, professional drift cars, sometimes you see a M50 turbo powered Nissan Silvia... Thanks!
Hmm I found that video very interesting. I understand the rb25 block is heavier than the 2j but fully built isn't the rb25 engine still considered lighter than the 1jz? Thank you for the video!
You should do a video of rb cylinder head vs jz cylinder head. Valve angle, sizes, materials etc... I think it would be very interesting and educational.
All the stats will never beat that RB note....
Would love to see the numbers from the "baby RB", CA18DET
K20 vs SR20
K20 vs 4G63?
k20 all the way. the sr20 is a very average 4 cylinder turbo motor.
K20 vs 2zz lol
Lucky Rooster what you got something to say 😂😂
Are you serious? K20s on a whole other level. SR's are nothing without its turbo. The DC5 type R is faster than Silvia's despite them being turbo.
Thanks for the comparison. Love my JZX100.
What about d RB20det and the RB24 carbrueted block ? ... those RB24 consist of d rb20 stroke and rb25 bore
So is it safe to say that a JZ can be remapped to rev higher than an RB more safely (with the proper mods)?
Also, the 2JZ is even slightly lighter than the 1JZ.... that's crazy!
Thanks for this you guys, much appreciated.
I would love to see you guys test a 7M-GTE out of a MK3 Supra. It's not as good as the JZs but I would love to see how the more common supra engine compares to the RB blocks
@@jzxtrd337 oh ok, but what about the 1g-gte?
Love these videos Andrew. Very interesting and informative.
Id love to see the comparisons with the heads, flow tests etc
How about we make a donation for all the engine block requests that people ask? Say chip in $10-20 each so we can get some data across different engines that can be picked up from wreckers
Michael De Leon we’re doing live stream of GT Block test soon. Hopefully some Superchat donations happen and help fund all these tests as we are spending our own money and time to make them happen. Need 300,000 views to pay for itself
@@MotiveVideo does watching the same video more than once from same account increases the count?
@@MotiveVideo I hope these videos get more global recognition because this information would have saved so many stupid forum discussions throughout the years. WHat youre doing is really great!
Seriously loving this stuff mate. Let's an old bloke know what he always suspected. 👍
These tests are going to convert Herman to the JZ life.
Almost at 100k keep them vids coming
Been waiting for this match up! 👍
Absolutely love these videos! Keep em coming
This channel is going places !! I love you guys already ! Keep it up
Mercedes M104 is an awesome inline 6 capable of over 1200hp on stock pistons acces to 3.6 liter diesel crank and super cheap.
Makes me happy I just bought a chaser 1jz gte
Would love an ej vs 4G comparison even though they are very different in design, materials, etc. still would be awesome.
Pls test the n54 bmw block ....
Would love to see a VG30DETT vs. the RBs and JZs.
yeah that'd be interesting. Or even the VQ
Interesting to see how the German versions of these fare in this test, the M50/52 and M104, both respond well to boost as well!
It's not that weak. I ran my 1J down the M4 from Penrith to Parramatta with zero water due to a blown radiator and still then drove it 1500km to QLD after replacing the radiator. 1J's are as strong as an ox. 👍
Im sure you did . How if almost all engine that run no coolant cant even idle without overheating . I call bullshit wven if the car was moving it will still overheat . Absolute nonsense and lies
@@_i-kr6eg I was thinking about his comment, and maybe if you run a big oilcooler as you would in a performance car, and stay off the throttle, you may get enough cooling from the oil. I´m on the fence on this one. Ive been on a few events where they empty a car of its fluids, (oil and coolant) and put a rock on the gas pedal until the engine siezes, they usually go at rev limit for a couple of minutes still. Out of the coolant and oil, the oil is the most important. Many people fill their blocks with concrete for drag applications, including my boss, and he has had no problem with it, think he still has a little bit of coolant left in the system though.
Next time you want to delete my comment Andrew, delete his BS comment too. 😡 If he wants to call me out, I'll call out ALL the BS he has posted the past 4 months on here, simples. 👍
The choice between a 25 and 1J is easy for me, if I've got a Nissan, I'd use a 25, if I've got a Toyota, a 1J, I've seen 25s slightly out perform 1Js with the same sort of setups in street cars, 1J needed a bit more boost, once again both awesome motors
I'd like to see a VW 06A and EA888 since they're made of iron too. Some VR6s to compare against the Japanese engineering would be fun to see.
Thanks for this @motivevideo seeing Herman reactions was too funny
Keen to see the rb rrr block
Would be an awesome comparison against the 2jz.
Saw one for sale about 3 years ago. Starting bid was 10k. Sold within that day without disclosure of the sale price. Havent seen a geunuine one since then. Dont think anyone would sell one now considering GTR tax atm. 250k for a stock nur spec dayummm
completely impractical i know but id love to see a 7mgte and how that stacks up to other RB's and JZ's. Supposedly the bottom ends were quiet good.
Cmon give the rb20 some love show us how it compares
I dont think those can make enough power that the block is going to be an issue.
@@zyoungson215 Actually, a Russian drifter Gocha makes his SR20VETT bring 700 HP in his NGK Silvia S15
@@driftmouse_official
That's an SR, not an RB20. There has been plenty of development been made on the SR20 due to the popularity of the S chassis and the lengthy production run. RB20 was produced very briefly and only used in R31 Skyline in NZ market I believe.
@@yjkader Oh, sorry, I just realised I answered a wrong comment upper)
Exactly what I was thinking! I'd like to see an RB20 block.
these are great, thank you for doing these videos
this is like Sword vs Katana nice video i hope all the 1jz are good
Hardnesses will be different in different areas of the casting. Thicker parts are usually softer.
Do some aluminum block tests if possible. Like later model BMW engines, or maybe Volvo modulars.
Wow the JZ kills the RB in every aspect, didn’t realise they dominated so much, was expecting a more even competition.
nice..what about 7m-gte vs jz?
I'm at 540 whp on my 7mGTE and had nothing but great reliability with my 7mGTE and 7mGE motors in the past but the 2jz is just a better built motor and has been proven that over the years. I like em both which is why I also have a GS300 with a 2jz for a good reliable daily driver.
lol..I did that too in my supra..but I would like to see comparison :)
@@Shwalker07 I'm my experience, it has always been an issue of ignorance or the inability to do a proper costly engine build to to have a reliable 7m. 1000whp is easy if you know what your doing. So far 1750whp is the most I have seen and still going strong on a drag application. By far the cheap and easy way to make power is JZ. It's really the engine for dummy and overly proven.
@@Shwalker07 Stock internals? MHG?
@Tex 13 Good point! It’s a matter of nostalgic pride for me and boredom of the 2JZ since being around them from 92’. When you say I make 1000whp+ out of a JZ it longer is special and know one cares much now a days. You tell people I make 1000+whp from my 7m, your suddenly the most interesting man at the car meet. I love to test a 7m block just like they are doing in this vid with the same tester to keep the consistence in the data to these tests. I will be a while until I can. Here are a few things I can recall. The oil inlet is 18mm vs the JZ 15mm. The 1990+ blocks are the way to go because they were much beefier then the previous ones. The change was due to what they learned from Group A racing. In fact in 1991 the Supra with a 7m took 1st in the 12 hours at Bathurst. Those 90’blocks have some really big supports on the bottom ends. Also the 7m does come with slightly larger mains and bigger heads studs over the 7m. If your goal is 700whp max reliably and want the cheapest way to get there, go JZ. If your going past that and want to make big power then the cost on both engines will be similar. You have to do the same things using a complete array of quality parts and work.
Wonder if Yamaha also building pianos has anything to do with it? The attention to detail and finer points, same work ethos in their mechanical division?
Can you please do a rb25 vs rb25 neo comparison as theres a lot of myths and guessing on the forums. We like to understand the difference in internals and heads and what it does to power with the same mods
what about the rb26dett vs the vg30dett
I wonder how would a siamese cylinder block hold up in endurance racing. Like a 12 or 24 hour race. RBs have seen sucess at the Spa 24 hours and Bathurst. I dont know if any of the jz blocks have endurance race victories.
@Ricky Saunds what won it in 91 and 92?
@Ricky Saunds so what are you sayimg? The supra has more race wims and championships than the skyline?
@Ricky Saunds I guess it was a supra that won the 1991 Spa 24 hours. Not a Skyline. Right? I guess the supra is the most sucessful Japanese car in racing amd not the skyline. At least in your world.😆😆😆
Calm down conrod😂 youre just salty because rb's are shit compared to the jz family and its not he motors that made skylines fast its the awd attessa systems and all that advanced supsension and driveline lol
Skyline win because their 4wd system that no match for rwd at exit acceleration from corners but toyota begin with e503 aka 2.1 liter 3sgte which dominate JGTC 500, jgtc 300, WRC, even pikes peak rod millen 1000 hp use e503 engine.
Supra with 2jz is never win any competition because the power delivery too wild,
PLEASE do a comparison between RB25, 1JZ, and the BMW M50B25!
Great video, straight to the point no bs
RB30 Stroke is 85mm hence 2962.5cc where as the the 2J is 86mm - 2997.3cc
The fact that the JZ engines come with VVT is a huge advantage also
rb25 have vvt too
How is it that someone today doesn’t realise 25s can come with vvt?
I wonder if there is one for LS and LSX block since they say it can hold a lot... can we have a those block interviewed too???
Pls test some BMW blocks. M50b25 (the german 1JZ) or S50/S52, M30B35
These vids are really interesting, thanks ;)
Get that bmw m50 iron block to the test! Its propably not nearly as good as these but id love to see how it goes since its a common engine for turbo projects in my country.
Surprise surprise ... good video to show guys when they ask why my r32 has a 1jz in it though 🤣
this is cool and all, but since you do so many test of race proven 6 cylinders, can you test a race proven K series 4 cylinder honda engine? I wanna see it's hardness and thickness of bores. Thank you. K series being some of the most utilized and best 4 cylinder engines readily available, much like the barra in Australia.
Ran Dom send us one stripped, cleaned and ready to go
Wonder how an sr compares to all the blocks. Really enjoy these vids tho! Thanks
Not well as they aren't cast iron
I mean true but bare sr blocks can handle a suprising amount of power
It would be interesting if you could also do the RB20DET block just to see what you find.
Michael Barnett already have
Just can’t edit and release 10 videos in a day
@@MotiveVideo Fair enough mate, more than happy to wait. Just stoked you didn't leave the RB20 out. Very interesting series.
curious to see how the old dunnydore mang mangs compare, 5ls, ls, boss 260, windsors etc purely out of curiosity lol
Should do one on a 3sge- 3sgte block vs 5sfe block.
would there be any difference between std rb25 and rb25 neo?
Another quality Vid
Question. Whilst this series is very interesting, does all of this data basically not matter unless you are aiming for high to ridiculously high power figures? ie 1000hp and up?
@Alex Little ?
You think this engine block comparison series is popular?
Corporal Punishment numbers don’t lie
@@MotiveVideo I click straight away and cannot wait to see what's next keep up the good work guys.
The only thing that is better about the RB is the exhaust is on the opposite site of the engine to the brake booster, if you care about that kind of thing ;)
Toyota makes real good blocks! But I would like to know about some 4 cylinder ones, something that is against the SR series. Against a 4A? Hehehe
Can an alloy block comparo be done? vq25det, ls1, sr20det, 5.0 coyote as a suggestion? Dont know what mitsi or toyota blocks are alloy but throw some in the mix as well.
