@13:44 if anyone is doing this with ARP head studs, make sure to coat both sides of the washer and drop it down into the head before you install it onto the studs; you cannot do it the other way around. @20:49 those two allen bolts are for the first VVT-I selenoid cam cap under the valve cover.

As someone who loves cars but doesn’t work on them, and doesn’t have first hand experience working on them.

This is the kind of content I've been waiting for! Longer form, more detail. Please start a series from this; tearing down and evaluating legendary engines.
I love that you explained so much about this engine. I was just very confused from a mechanical standpoint why you didn't rebuild it while you had it apart. All that labor just to show us the amazing guts of a 2JZ. Thank you for doing the labor so we don't have to.

Stock cranks have seen 1500whp multiple time. Love how they put the head studs in block before installing the head. And then skipped to cams. Cuz they had to pull them back off to be able to fit washers in head
You should do an LS teardown and see why its the most reliable, and the most common engine swap! Also, please put the 2JZ in the Silvia. It has no cons! It will fit well, It is a video that would do well, we would all love to see it, and then zack gets his car fixed!
A while back at a local car meet, I watched a high school team of mechanics fully disassemble and reassemble a 427 in... 20 minutes, or somewhere around that. Absolutely insane to watch since they had exact coordination, didn't see a single fault while they worked.
Yes, hot rodders of tomorrow engine team! I'm part of that, and as of right now if my team ran a 20 my coach would yell at us! Last year first place nationals walked away averaging around 16:50 I think? recently in practice we average 17 minutes but we're hoping to get closer to 16, and hopefully below 16 (between 15:30-16:00) before state comp. We're slow right now as we haven't been practicing much but after a bit 16's become our average that if we run a 17 we're mad about it. sorry for long response, just weird to see something about my competition in the wild lmao.
@@bearymos4805 just watched a competition. That's awesome to see kids so into cars. Keep up the good work. I'm a pro mechanic and you guys are way faster than me or anyone I work with!
I think this is one of your best videos yet, I've been a fan since you guys were in the garage attached to the house, I think even before jobe came to the scene as a mechanic. You guys have done an amazing job, I'm proud I've been with you through your journey. And I'll see it through to the end
Tear downs are great. I think it would be cool to do a EJ22 if you can get one. Also maybe a comparison side-by-side tear down of a Honda K and B series might be interesting.
its all in the block. The quality and hardness of the casting material, the consistency of the castings, the siamese bores, the bore thickness from ~5,5mm at the bottom up to 8+mm towards the top (compare that to a "good" RB30 block which would be around 4,5mm at the top of the bore), ~10mm deck thickness (RB30 is around 8mm), 11 oil return holes at 15.5mm wide (RB30 has 5 return holes at 8mm).
this is super sick. love seeing jear bear and zach together and these engine breakdowns are also dope. this would make a dope series tearing down commonly used motors. k24, rb motors, sr20, k20, m50, etc!
The RB would be great, especially if they show how it evolved over the decade or so it was made. Hands down the best sounding one when turning at full tilt!
The GE has alot more in common with the GTE than most people think. It's just ALOT easier to swap instead of modifying. Which is probably why the prices of GE's have increased as well.
@@sameerulhaq9928yep, pistons are still different tho. I believe the GE non VVTI pistons are higher compression and doesn’t have oil squirrels. Funny how it’s still a bit different.
Now THIS is the content I subscribe to Donut for!!! Never stop you guys. I truly feel like I learned a lot. Keep up the excellent work. Next up: 2JZ money pit Miata.. Maybe? Come on, You know we all want to see it Jobey
Wow this engine is amazing, my question is, as small as something can be, you can always make the most out of it, so I wonder why other companies didn’t focus on this kind of efficiency and durability when making engines, or just any kind of cars, the engineering and thought behind it is so well planned
I don't know if it's important or not, but... I remember a video, when James mentioned the gentlemen's agreement and those 276 hp. He also said that it's kind of a weird number. But a lot of companies measure power in KW (kilowatts). And knowing that 276 hp = 200 kw (depends on numbers used, when calculating), those 276 hp don't seem that strange anymore. The gentlemen just agreed to 200 kw.
At that time, Japanese car manufacturers measured their engine's horsepower in german style, ps. And in that way, the horsepower number is exactly 280 ps. Still odd, but makes more sense than 276 hp, right?
Still can't believe how nice and smooth a 2jz is to drive , I picked up an Aristo recently and i'm so glad I got it over my other options. So fun to drive just part of me feels bad putting ks on it but im hoping to make it last a long time
The 2JZ doesn’t make a lot of power at all. And that’s what makes it so awesome. 🤔 The crankshaft on the 2JZ was 20Lbs heavier than the RB25. And it has its way further away from the pivot point. When on something rotating you want to get the way to the center, and do you want to try to reduce it on the outer edge.... So that means the 2JZ would have to make more energy output to move that amount of weight to the same Power output as the smaller engine. And it wouldn’t be as rev happy, so it’s also going to be harder to make the same Hp number that the rb25 does too. And on the topic of Hp disadvantages. The longer stroke of the 2JZ means it will do better after 5,000Rpm. So the fact it that the Rb25 had many advantages to help it make the “270hp” with a 2.5 vs the less efficient heavyweight 3.0L’s “270hp.” .... but the reasons that it is less efficient, Are because they leaned towards their ability to survive a lot of different kinds of forces and twisting. It’s not it efficiency to make and convert energy that make is so awesome. They simply built a more robust engine that could handle more power. And have a balanced “ Square cylinder geometry.” N/A 2JZ’s ain’t some 1,000 or even 800hp beasts.... they handle and withstand extremely high combustion pressures. And that is what makes them so awesome. ...But at the end of the day they don’t make a lot of power...they just withstand its abuse.
You could do another hi-low series with two 2JZs after figuring out a car that could be a sleeper that has it, like an old toyota chaser or something! Just an idea but keep up the great work you guys!
Zach and Jeremiah have hilarious chemistry, like Oirrl and water! They get into a tiny fight 12:13 And then they make up 14:16 but start up again 14:49
This is one of the coolest videos you guys have done. Don't get me wrong I love the whacky stuff too! Just saying I wouldn't mind seeing more videos like this one!
That'd be neat. I've got one in my driveway that I just sealed back up. I'm going through the headache of trying to get all the air out of that horribly designed cooling system now.
Gen 2 LT1 rebuild. Late model C4 corvettes are cheap fun, but not everyone can afford an LS swap right away. A fresh one with 300hp can spin tires just fine. Great cheap project cars.
TEAR APART MORE ENGINES!!! PLEASE!!! I'm a Civil Engineer but I love all aspects of engineering and if it wasn't for how vehicles are built I would not be building be structures. Tear apart more engines and rebuild them its sooooooo Fun to see you guys do it. I Cheered when she fired up. J & Z .... You guys are a great fucking duo for this.
Love how those guys were ready to make bets that it wouldn't start. Guess who was wrong, huh JZ is for Jeremiah+Zach. Your duo is brilliant, keep it up 🔥
2jz is far stronger. One of the Aussie channels (might have been Motive Video) did sonic testing on the block thickness and a whole heap of other tests. 2jz won nearly every single test.
@@thehomelessproject3784 100% a far better comparison (despite the extra litre of displacement). That’s what makes the barra and intech so good, all that torque!!
I know you guys work mainly with cars, but another legendary Toyota engine is the 2UZFE from the 1st Gen Sequoia/Tundra. They're notoriously bullet proof. I'd love to see a tear-down and rebuild of one of those!
I'm pretty much a "jdm boi" but there's no way in hell i'm dropping 10k on that hunk of iron, the attractive of the jz engines is the "cheap" power we can get out of them, 10k puts you into a b58 powertrain like the mk5 supra, which has already been proven for 1000hp as well lol
@@tfhssn I have taste, i like the 2jz but the appeal of that engine has never been dropping 10k just to buy one. A B58 here is 4500€, a 2JZ could be bought for about 2-4000€ prepandemic, so yeah, it's not about taste it's about using a cheaper and lighter engine for cheaper that will still last and spending the difference on better cooling, suspension and transmission.
So the 2J has this super cool exhaust manifold gasket that is just another reason why the 2J is so reliable and robust from the factory, and why it can handle so much power. The 2J has this really powerful EGR system thats just another reason it can handle so much power and is so strong and reliable from the factory.
Just saw your 2j teardown and rebuild. Absolutely awesome please do more engines and i would be ok with a longer version very enjoyable. Thanks guys and as always good job 👏🏽

It’s already got an RB, this engine needs a new project.

.... but the reasons that it is less efficient, Are because they leaned towards their ability to survive a lot of different kinds of forces and twisting.
It’s not it efficiency to make and convert energy that make is so awesome.
They simply built a more robust engine that could handle more power. And have a balanced “ Square cylinder geometry.”
N/A 2JZ’s ain’t some 1,000 or even 800hp beasts.... they handle and withstand extremely high combustion pressures.
And that is what makes them so awesome.
...But at the end of the day they don’t make a lot of power...they just withstand its abuse.
15:30 Uhh, That's wrong, crank to cam would be 2:1 for a 4 stroke engine; 2 Crank revolutions for 1 cam rev.
Their bromance over the last few months seems to be getting better and better 😂❤
You could do another hi-low series with two 2JZs after figuring out a car that could be a sleeper that has it, like an old toyota chaser or something! Just an idea but keep up the great work you guys!
The high car is just a Supra they bought, and the low car is a IS300 they heavily modify 😂
i had no idea how advanced the 2jz is thanks for making such a digestible and fun video
jerry and jobe doing mechanic stuff are always the best vids, now put it in the miata
LET'S GOOOOOO BABY,2JZ!!!!❤️🔥🔥🔥🥵
Zach and Jeremiah! My favorite tandem!
Zach and Jeremiah have hilarious chemistry, like Oirrl and water!
They get into a tiny fight 12:13
And then they make up 14:16
but start up again 14:49
Keep the technical content coming!
Loving the switch back!
This is the kinda video you have to watch over and over for it to transition from entertainment to information. :) Love it ...... MORE OF THESE.
The quality of these videos, the editing, the shooting, everything, is so professional and well done.
These two Donut guys have the best chemistry and the same style of humor. I really enjoy watching their episodes!
More engine teardowns, please!
I’ve learned more about engines in this one video than I knew my whole life … 🤯
Dude?
Those extra bolts look *awfully* similar to the ones pictures at 22:27... just saying
These 2 guys are good together, they should start their own channel 😂
I think it'd be cool to do an engine build on one which is very efficient, seeing how it achieves it like this it's power
This is one of the coolest videos you guys have done. Don't get me wrong I love the whacky stuff too! Just saying I wouldn't mind seeing more videos like this one!
Would love to see a rebuild of a vq35de. That’d be pretty sweet
That'd be neat. I've got one in my driveway that I just sealed back up. I'm going through the headache of trying to get all the air out of that horribly designed cooling system now.
Gen 2 LT1 rebuild. Late model C4 corvettes are cheap fun, but not everyone can afford an LS swap right away. A fresh one with 300hp can spin tires just fine. Great cheap project cars.
Donut gettin' consistent again🎉🎉🎉❤

Can't wait to see what this goes in! Also, how long will it run before we find out where those two bolts were supposed to go? 😂
TEAR APART MORE ENGINES!!! PLEASE!!! I'm a Civil Engineer but I love all aspects of engineering and if it wasn't for how vehicles are built I would not be building be structures. Tear apart more engines and rebuild them its sooooooo Fun to see you guys do it. I Cheered when she fired up. J & Z .... You guys are a great fucking duo for this.
Love how those guys were ready to make bets that it wouldn't start. Guess who was wrong, huh
JZ is for Jeremiah+Zach. Your duo is brilliant, keep it up 🔥
Great stuff as always!!
How do you know if you can’t possibly have watched
Next we need the rb and a comparison please 🙏 😊
2jz is far stronger. One of the Aussie channels (might have been Motive Video) did sonic testing on the block thickness and a whole heap of other tests. 2jz won nearly every single test.
@izzy031096 it's a beast what would be good actually is a Ford barra vs a 2j and then a BMW B58
@@thehomelessproject3784 100% a far better comparison (despite the extra litre of displacement). That’s what makes the barra and intech so good, all that torque!!
@@izzy031096 Hopefully they see these messages 🤣🤣
I know you guys work mainly with cars, but another legendary Toyota engine is the 2UZFE from the 1st Gen Sequoia/Tundra. They're notoriously bullet proof. I'd love to see a tear-down and rebuild of one of those!
Bring up to speed back!

I'm pretty much a "jdm boi" but there's no way in hell i'm dropping 10k on that hunk of iron, the attractive of the jz engines is the "cheap" power we can get out of them, 10k puts you into a b58 powertrain like the mk5 supra, which has already been proven for 1000hp as well lol
Then you have no taste
TEXT THE ABOVE USERNAME TO CLAIM YOUR GIFT 🎁!!!!
@@tfhssn I have taste, i like the 2jz but the appeal of that engine has never been dropping 10k just to buy one. A B58 here is 4500€, a 2JZ could be bought for about 2-4000€ prepandemic, so yeah, it's not about taste it's about using a cheaper and lighter engine for cheaper that will still last and spending the difference on better cooling, suspension and transmission.
You're more of a money guy then a car guy I see lol
2jz in bmw drift car
K24 v 2JZ showdown... the suspense is killing me!
Use me as the Jobe “robust” button
So the 2J has this super cool exhaust manifold gasket that is just another reason why the 2J is so reliable and robust from the factory, and why it can handle so much power.
The 2J has this really powerful EGR system thats just another reason it can handle so much power and is so strong and reliable from the factory.
This was fun, now let's see a Mazda 13B-REW get the same treatment, or a VW VR6!
Just saw your 2j teardown and rebuild. Absolutely awesome please do more engines and i would be ok with a longer version very enjoyable. Thanks guys and as always good job 👏🏽
This episode was awesome! I learned so much. Would love to see more iconic engines being torn down and built back up. Nice one!
