No sh*t, we've finally done a "What's so special" video about the 2JZ! Often touted as one of the best straight six engines on the planet, Toyota's 2JZ has reached almost mythical status in the tuning scene, but why? It can't all be because of some buster with a penchant for tuna on white with no crust, can it? Join us as we tear one of these legendary units down and take a closer look at what is inside.

No shit, we're finally doing a "What's so special" video about the 2JZ! Often touted as one of the best straight six engines on the planet, Toyota's 2JZ has reached almost mythical status in the tuning scene, but why?
Please make a plug n play for the jzs161.
Consider the Boss 260 and how it is a pretty decent engine but it dors have some factory issues that need upgrading, maybe elaborate how the exhaust valves and cam caps are different between higher performance versions and how the lower intake is the best one for the 5.4 modular engines, be good because everyone just trashes on them without knowing anything about them lol
Because it was on fast and furious is about 90% of the "why"
Awesome thanks guys! Also, huge thumbs up to your email support team they helped me get my harness finished up yesterday.
It’s so overbuilt, it’s everything we love about Toyota, shown off in a single motor. No huge weaknesses, just amazing smooth performance with mechanically durable internals. Simply the best. And the fact they still offer reasonably priced replacements this far on... Its a testament to the brand
As an engine management calibrator these videos are nothing short of amazing, the nuts and bolts mechanical walkthrough is priceless; I honestly enjoy every minute of it! The history lesson is also a pretty decent compliment to the wealth of information on hand.
A great many thanks for making them what they are, to churn them out can’t be easy and everyone involved making it happen deserves my overwhelming gratitude! They’re really a treasure to resort back to over and over again.
I can hardly wait to see what engine is looked at next, cheers!
Surely there are some 2K Barra comments inbound? 😆 Great video guys.
Yeah I wasn’t planning on fuelling the fire, but I think we all know what the real best engine is…
@@deputycartman ya damn right - a frantically spinning, fire breathing Hiroshima Screamer!……..I’ll see myself out
you guys get all the salt
@@deputycartman why not have both.
Lets not forget about the Atlas 2900, 3700, 4200
This, The Skid Factorys video with Golebys and Motives video with PRP. That tells you everything you need to know about the JZ engines.
Actually ya can add Finnegan’s Garage episodes with their boosted NA JZ Charger to them. Really illustrates the design strengths across the range.
Whats it telling huh?
no real street? he has hours of knowledge on just this motor
Underrated channel. Noone else goes into this kind of technical detail. Thank you.
27:56 Scotty, I really appreciate your reference to "controlled combustion." Far too many people still call it an explosion - including a number who really should know better (unless they're just accustomed to a lot of knocking - hey, it could happen, right? 😛)
People who worry about controlled combustion don't have videos of them working on cars.
It also has a ton of oil drain back so it doesn't starve for oil at high RPM! Great video.
Once again, great Toyota engineers hard at work to make one bad ass engine 👍🏾
Excellent video! I remember building my 2j a few years back, which now powers my s14. It was an experience I'll never forget. This motor is so special to me.
I remember all the guys in the late 90's and early 2000's swapping the 2JZ in their S14 ...
Today i have my MKIV Supra and my S14 side by side.
JZ POWA!! 1JZ are stout too. amazing the power that can be achieved on a SBE
One of your best presentations, thanks Scott 👌
Great tear down and well explained , I’ve subbed 👌🤟
The sequential turbo system does actually use both turbos after 4000rpm. Has a very interesting system for blocking the hot and cold outlets of the second turbo to stop it from spinning. There's a 3rd valve that opens to allow it to start spinning at I think it's 3500rpm from memory. Then at 4000rpm, the other valves open up and then both are working like a parallel system.
Does this apply to the twin turbo 1jz?
@@BoomBox02 Nahh, they were parallel. Then the VVTI ones single turbo
Yeah, spot on. However when I ran BPU, I fixed the actuators on open and both turbos worked at 4000rpm, cheap man's single turbo kit :) fun times, hated to work on the TT kit, such a tight fitment
Yes it feels like nitrous when that 2nd turbo opens and you feel it just after 4k rpm. But you got to be on the throttle, otherwise you will never feel it.
It's a perfectly balanced engine that's probably one of the reason why it's so good
Its more the block itself being able to hold 2000 crank hp ....
@@ACommenterOnCZcams The heads are used on engines making 3,000 hp.
You'd have to be doing something really wrong to have an unbalanced I6
Love these videos! So informative.
Hi mate, minor correction, the sequential setup on the 2jz is a primary that runs on all six cylinders, which then pre-spools the second identical turbo, before bringing it online to provide parallel twin operation, ie. two matching turbos each fed from 3 cylinders. I am in the process of setting up an elite 2500 to run the factory sequential system with high flowed JDM CT20 turbos.
Eeeyyyyy I'm doing the same!! Did you get the harness as well? And if you did, and installed it yourself, you had any problems doing it or is it just time consuming to route it properly cos I'm scared of fucking mine up lol
@@THEedcbb3 I'm using the premium harness, adding oil pressure, fuel pressure, flex and a DBW throttle then wiring and re terminating everything.
If you use an after market clutch with a harder pressure plate, do NOT ever keep your foot on the clutch. Regardless, never keep your foot on a clutch at a stop, take it out of the gear :) Great video, 2jz was the first engine I ever took it apart, so easy to work on them :)
I would love to see inside the 4AGE . Such a great little motor
Two years Running an Elite 2500 with a terminated harness. Like mentioned it was very easy to install, lots of extra circuits pre-wired for additional sensors. A lot easier than trying to modify a stock harness. Worth the cost to go with terminated harness vs flying lead or jumper style. Added IC7 display and touchpad with the nexus update, its next level cool! 600whp @ 29psi unopened long block non vvti in a Tundra. Thanks for sharing!
The factory turbos are the same size. In lower rpms only one turbo makes boost and when you go higher in the rev rance the second turbo slowly comes on. In higher revs both turbos are working at the same time.
Secondary turbo has a larger exhaust housing if I remember correctly
I'm pretty sure you remember incorrectly.
@@NearCry91 I looked at the exhaust housings of the stock turbos, and could have sworn that the 2ndary had a larger housing.
Great video. I am building a 2JZ-GTE right now and it's my first JDM engine build. Excited!
Yah man the 2JZ is tough as nails. I thought I blew mine up a couple of times already after the NA-T conversion and street tuning but nah she keeps on boosting.
great vid m8
Hello from Sweden. Really nice video! Here we don't use Haltech that often, MaxxEcu is a more common system, of some reason... But I really appreciates this video/series so I might will test a Haltech system in in the future. Keep up with your good work!🙃
Very good educational video, I would love to see you do a Toyota 1FZ-Fe strip down & walk through.
Thank you haltech and thank you Scotty for another educational video loved it awsome
Great video, mate!! 2JZ the world!! 🔥🔥🔥 Can you do a 7MGTE breakdown?
Thank you very much for this great educating review. Best regards, Miha
Two Jay Zed
Great video. Love your channel! The Renault 2.0 12v engine has been missed though. Quite a rare engine. Fitted to the Renault 21 TXI.
awesome video guys
I think 2 videos are in order. The 4AG(Z)E and the 3SG(T)E. :)
Those are 2 engines that really demonstrated that Toyota knew how to make an engine, before any type of cam timing/phasing was in place.
Great vid guys ! Would be great to see your annalise on the 1hd fte cheers
Great Video first of all and good explanation for non engine builders like myself. One engine I would like to see an episode about is the 3S variant that Toyota used in some of the Supra's for racing like you mentioned and possibly some explanation as to why those were chosen over the 7m series or the JZ series. Also if you could show the Iconic "Cheat" valve that got them disqualified using the Celica GT Four in Rallying.
The 3S-GTE is the same engine (essentially) as the MkII MR-2 turbo and the Celica GT-Four. They used it (longitudinally) in the JGTC Supra because the GT500 class rules were set up to limit the engines to around 500 bhp (or more likely, PS... hence the name, and likewise the GT300 class cars were limited to around 300 HP). The 3S was a noticeably lighter and shorter engine since it it was only a 4-cylinder, and they would have no problem making 500 HP on a race variant of that 2.0 liter inline-4. The narrower powerband from getting 500 HP from a 2-liter vs 500 HP from a 3-liter would be a minimal issue since race engines spend their lives at the top of the rev range anyway, and the marginally reduced throttle response ("turbo lag") was an easy sacrifice when compared to saving a sizeable chunk of weight from the heaviest end of the car. Weight is the enemy in racing, and reducing weight while making the weight distribution better is basically the holy grail for a motorsports engineer.
Edit: As far as the restrictor "cheat" from the Toyota WRC cars, he'd be hard pressed to make a video about it, I think. There are almost no images of the device itself on the internet, only a few drawn diagrams, and I imagine the devices themselves were all destroyed afterwards.
Toyota's 4.5 1fz fe engine. Love to see that straight Six pulled apart. :)
Very cool info
Should have really elaborated on the deep connection between Toyota and Yamaha.
They are really the performance arm of everyone.
Meh. The 2jz was made by TOYOTA. They took what they learned on the 1jz and elaborated. Yamaha was the go to for literally everyone who wanted a badass engine. Ford, Chevy, Toyota, Yamaha designed or blueprinted many of the great motors from the 70-00s... But the 2jz was not a Yamaha engine.
@@freestyleskyline well if you look deep enough Toyota turned to Yamaha with the head work starting with the 1jz, and the 2jz when they were satisfied with the durability and were looking for performance
@@ljason888 actually I've looked more than deep enough and I know the whole history. There's a reason why Yamaha has their name on the 1JZ head but nowhere on the 2JZ head
@@freestyleskylineNot really here to debate, as this is about the 2jz, but nearly all the toyota engines with "ge" or "gte" has Yamaha stamps on the head, even if the 2jz doesn't have such, then it simply has been slightly revised as the head is nearly identical to the 1jz that was definitely had the yamaha stamp on the head. Just because its slightly different doesnt make it originally toyota design, all they did was modify the original yamaha design.
Great video! Can you do one of these videos for the 1uz/1uzvvti/3uz
Another 3.0 inline 6! Volvo SI6 aka B6304.
Factory came as a 350hp turbo variant. Haven't really seen a modified one, I'd be interested to hear your take on what you think it's weaknesses may be and what numbers could be possible.
So glad someone finally made a video on why the 2JZ is so good -_-
Scotty!! You the Mann!!
2 J ZED dammit!
Edit: there were a number of reasons Toyota used the 3s in the JGTC race cars and it's not just because they had already been developing it. Using a 4 cylinder enabled better weight balance, was lighter and as turbo restrictors were in use, the 3S gave them their power goals with a better power band than a 2jz if it were to have a restrictor.
Zee. Not zed.
@@cavalierliberty6838 most of the former British colonies (as well as the Brits themselves) still say "zed", I think those of us in the US are the only ones who say "zee" 😁
Thank you for the wonderful video. How come the gaps on the compression rings were so big? I thought that they had to be tiny to stop blowby? Not like they were expanded beyond the circumference of the piston either?
Video has been favorited
awesome vid, heaps educational, BMW M10 engine
Nice walkthrough mate, N54 BMW engine would be nice to see the inside off please.
The main caps and the crankshaft looks very similar to the 7m, I just disassembled mine yesterday
I would love to see the VG30DETT done.
Me too
great overview. I would love to see/hear your opinion about the small 4-pot CA18DET :-)
Awesome segment. How about the Nissan vg30 motors. They where use in so many vehicles, possibly a very underrated motor. The late 80s and 90s seen them in Imsa race cars. And dominant in racing.
Great vid, considering building one from a new block and head and dropping into an 86
No you are not
Very impressed with your breakdown video. I need this engine for my RA28. But like you said they are like hens teeth and more expensive than a good second hand car?
I'd like to see a "what's so special" on the SR20, My Dad went to Japan in 1990 and imported the first GTiR to Australia, then tried to rally that lead tipped arrow.
Scotty the tuning fork!!!
More please more please...
Check the mercedes M104.980 and M104.992.
Also,om606 !
amazing
Would love to see you do a video about 24v VR6.
dual VVT dohc 3.2 V6 with a single cylinder head
Love that motor
Wonderful!!!
4AGE 20V silvertop or blacktop engine
Jay Zed… we’re Australian Scotty. Come on
plug and play you say, so you've figured out the etsc-i throttle body control and bean mpx network then for the vvti version
Should do a look at the 1FZ-FE and the TB48DE, rulers of Arabian sand drag racing.
Would love to see the Lotus/Toyota 2zz GE engine strip down btw :D
Have you heard of any in old fj45 landcruisers ? Im keen to convert from 253 V8 , thanks
Would be interesting to see an old side valve VS overhead valve 🤔
On some toyota engines like the 1nzfe, there are different and aftermarket, vvti solenoids that work better than stock. Never looked up anything for them on 2jz but I am a little curious now.
Just bought a 98 gs300. Replaced the camshaft seals without taking the valve covers off. Only remove the pulleys to get to the seals. Mark the teeth with white marker to the belt, jam something down between to hold the belt tensioner. A pipe wrench will hold the vvt to remove the bolt and a screw driver though the sprocket for the other. Took less time than two hours.
Also the vvt can stay in place, just pull the 5 bolts to replace the O ring to stop the leak. Took me 20 minutes.
That's heaps ghetto
Daihatsu charade....LOOOVE those things
Great engine 🤙👍
It really is!
Two Jay Zed boss, Zed!
Would like to see a video on the vq25det
Would thw same thing happen on a motorcycle engine suzuki 500 but instead of the coolant hose breaking .the fuel line popped when we're running for over an hour causing a fuel leak?
I'd love to see a video about the 1uzfe
i believe the next engine in line for a what's so special; is the TB48. these things need to come into the spotlight more
They’re special in the Arabian gulf!
@@Agent.K. absolutely. The amount of ridiculous-power dune trucks out here is mind boggling 😅😅. And they still drive them on the road, full interiors and everything.
I love the 2JZee and the 300ZeeX and the GPZee1000.
"just put the socket on the exhaust stud and wind it right out"
I wish I could believe that lol :)
can u do a explainer on 13B (rx7's engine plzzzzz)
Hope you’ll do one of these vids on the k series Honda 😎
Here you go! czcams.com/video/nJ3tlKsPfLg/video.html
Can you do the 3SGTE next ? many say it’s the 2JZ of the four cylinders
you mentioned the M series motors, but what about the 1G?
the little 1G-GTE was a pretty good little motor and preceded the 7M
Do the legendary Mazda B6ZE next
Hey mate if you can do a video on the Nissan Vh45 engine please!
Does the 2500 with the plug'n'play kit include a basemap ?
Basmaps aren't pre-loaded, but they are available to you :)
Probably worth mentioning that the VVTi GTE engine was never released in the USA so you can't put USDM intake cam in it like you can with a non-VVTi 2JZ-GTE.
Also, the VVTi mechanism itself is pretty much disabled around 5k RPM and the VVTi GTE variant also has a slightly higher redline compared to non, 6800rpm for non and 7200rpm for VVTi.
my ge non-vvti will rev to about 7.2/7.3k if i hold the gears, granted makes barely any power but it does it - even though the line on the dash is at 6.8k :)
I'm pretty sure the GTE VVTi engine was never released outside of Japan.
@@NearCry91 you are 100% correct
Volvo Redblock, Whiteblock(Modular engine) or the Volvo/Yamaha B8444S V8 engines would all be interesting run downs
curious to know of the makita really did just undo the crank bolt that easily? Nice work on the video :)
Hell no you need a super strong impact wrench or huge breaker bar lol
@@FightingSportsMediaso ive heard....the makita hi totque has 1600nm of torque...the milwaukee has similiar and can do it but ive already bought into the makita system so keen to see if anyones had any luck.

Can you please review the 1UZ?
Can you do the 2UR-GSE?!
The best straight 6 by far
Simple and reliable power.
I'd love to see a 1uz teardown
Yeah, big horse boosted and stroked like the Japanese Open Class drag beasts - HKS Supra and the Sard Soarer. First time I heard them growl- whooshing I was sold!

Great history
Reminds me of the 1997 volvo straight six but this motor seems to be thinner the volvo was wider also shorter great size motor this 2jz. The volvo motor was designed by porsche and is a sweet heart of an engine. I wish the pcv system was better though and better ac condenser rubbers are too brittle and the coolant desevoiur is a joke. They never changed it from the 80s. But what can I say I have had it for decades lol still drives me everywhere comfortably.
Let's talk about how people are taking the 2jz to the next level by using a 8hp70 8 speed transmission. Also one thing that makes the this setup even better adding a procharger to the mix and now you have a updated monster.😁
Why don't you do a PnP setup for the 2JZ-GTE VVTi? Why is the PnP limited to non VVTi 2JZ engine Supra's?
Could you make a techincally speaking about the 7M-GTE?😇
All my mate did with his 2j vvti was get piston and rods all good.
As you said unfortunately the impreza engine for the head gasket
An strip down of the ej255 would be good and what to upgrade to help make it more reliable 😁 before i start to look at getting more power from mines
A few weeks or months after this comment, they did an EJ video 😁 czcams.com/video/2IEiA6cbtCg/video.html
Boyssssss. I’m waiting for the EJ20. We need an EJ207 or an EJ20X/Y. Top of the breed for AUDM
We'll get on to that ;)
hope 2jzgte price goes up cos I just bought 2 🤤
