Toyota 2JZ - What makes it GREAT? ICONIC ENGINES #14
HTML-код

- What is up engine heads! Today it's time for a true modern icon. A combination of a number and two letters known by pretty much every petrolhead out there. Of course, I'm talking about the Toyota 2JZ engine and in today's video we will dive deep into it's anatomy to discover what makes the 2JZ so great.
In 1978 Toyota wanted a car that would complete with Nissan's very successful Z car, without making a whole new platform. So it took it existing Celica, widened and lengthened it a bit and stuffed the inline six M engine under the hood, creating a bond between the word supra and an inline six, a bond that exists to this day. The new super Celica was called Celica Supra.
The Celica Supra lives until 1986, until the word Celica and Supra came apart, and turned into two seprate models. The Supra was no longer mechanically related to the Celica, but was based on the Toyota Soarer platform, a larger and more upmarket platform that gave the Supra room to grow. The new mk3 Supra also received the latest and final version of Toyota's M engine, the 7M-GE and 7M-GTE, which made some pretty serious power for the 80s and gave the supra true grand touring credentials. In Japan the mk3 Supra was also the first one to get some JZ lovin' because in Japan it could be found with the 1JZ engine, signaling the way of the future for Toyota's sports flagship.
In 1993 we would see just how great the future was, because in 1993 Toyota revealed the mk4 Supra, and this time Toyota went all out. The mk4 Supra continued on the path set by it's predecessor it offered more of everything. More power, more equipment, better handling and less weight. But a rising yen and a weakening sports car market ended its career pretty quickly, and the world had to wait two decades for a successor. But these two decades are when the 2JZ legend was forged. In 2001 the Fast and the Furious movie came out and the whole world fell in love with the Supra. And tuners soon started pushing the output of the 2JZ, trying to find its limits. But there was an issue, it seemed the word "limit" wasn't in the 2JZ's vocabulary. In 2019 Toyota released the mk5 Supra and sigh of disappointment from the fan-base echoed across the world. Fans expected a 2JZ successor but received a BMW sourced B58 engine instead. And although the new car is objectively good, the new engine too, fans soon started demanding a 20+ year old engine be swapped into the new car.
An inline six is a beautifully balanced engine, because in essence it consists of two inline 3 engines which are mirror images of each other. This means that in practice both the primary and secondary forces are balanced out in an inline 6. The engine block is, as we know a cast iron closed deck unit. But there's more to it, the 2jz block is one of the most heavily reinforced blocks out there. It has 11 oil return holes that also act as massive reinforcement ribs. On top of this it incorporates thick curved surfaces for even more rigidity. And to go the extra mile it has a girdle which ties together the bottom of the block making it even sturdier. Watch the video for a bit of comparison of the 2JZ, the RB30, S54, and Ford Barra. The internals are, as expected massive and beefy. The crankshaft is forged steel with very wide and large 52mm rod and 62mm main journals. Rods are also forged steel and are meaty on all 2JZ except on the late model 2JZ-GE with VVTi. The pistons are high pressure cast hypereutectic pistons with an internal oil gallery that combines with the piston oil squirters in the turbo 2JZ block to directly cool the crown underside and reduce chances of knock. The 2JZ turbo has a 8.5:1 compression ratio, which is pretty low by modern standards but it does make cranking up the boost safer. The CR is 10:1 on the non vvti naturally aspirated 2jz and 10.5 on the late model vvti ones. We have 33.5mm intake and 29mm exhaust valves, along with a 45 degree valve included angle. The 2JZ head flows pretty well, but it isn't the best and some engines from the same era will outflow it, which means some porting is a good idea if your power appetites are very big.
When it comes to 2JZ tuning you know the drill. Upgrade the fuel pump and injectors, ditch the side mount intercooler in favor of a front mount intercooler, upgrade the cams and valve springs, switch to a big single turbo, get a standalone ECU and you're looking at 700-800 horsepower. If you want to go beyond this you'll need to open up the engine and get forged pistons and 4340 forged aftermarket rods. The crankshaft can stay unless you're going beyond 1200-1500 hp (depending on application). You need a billet block only if you're interested in power figures near 2000 hp.

what about the AUDI 2.7l V6 from the RS4 B5?
Can u do the Volkswagen VR6 iron block forged everything it’s like a little 2j and it can work in FWD configurations
what about a suzuki hayabusa engine, hasn’t changed much in all 3 generations and been around since the 90s. its been swapped into cars, water crafts, atv’s, converted to a v8, etc. proven to able to handle boost well and used in many different disciplines of motorsports. keep up the good work.
Hey buddy, I just bought myself a Christmas present; a 1994 LHD Twin Turbo 1JZ-GTE Soarer/SC300 project. It’s incomplete but it runs and drives so well! The stock twins are seemingly always in boost.
My 1990 MR2 Turbo and my 1994 Celica Turbo have finally met their big brother! Still got the LS400 holding down daily duties so my dream garage is finally complete! Just wanted to share that with someone who can relate.
@@negativeindustrial is it boosting?
So what you're saying, is Toyota should start making this again and sell it as a crate engine...
Yes yes.
They would definitely sell
It will sold out if don't make enough of it .
Toyota’s new heritage program is bringing some of these parts back. If they saw enough demand, they would definitely make longblocks available as crate engines.
The aftermarket is already selling billet 2JZ blocks and heads.
Any engine that generates a great power to liter ratio while retaining the major components of the stock engine while maintaining a high degree of reliability is the effective measure of a great performance engine...and the 2JZ meets that standard exceedingly well !
Exactly!
Only if it’s the Japanese made 2JZ , the North American version is thinner and smaller oil gallery
@@azarahwagner2749 Umm theres no american jzs?
I mean with turbos that not hard to do.......
And now it's the BMW S58 aswell.
Most other RUclipsrs: "The 2JZ is strong because it is a cast-iron, closed deck block"
D4A: "OILY RIBS"
Alumínium billet engines 2jz-s are even more nuts lol
RUclips's broken system can't keep me from this video. Been waiting for this since I discovered this channel.
When i open youtube, i always go to my Subscriptions. This way i do not have to rely on Suggestions.
Interesting that it was not the first video on this channel
Every channel of this type starts with 2JZ
@@kamilorzechowski6244 He started with the 4a in his own mr2 I think
I have a bad day but thanks
I work as a diesel technician, all the engine platforms are very similar. (Cummins, Detroit, cat, etc.)They all have a turbocharged in-line six cylinder, and they make power. Horsepower wise they usually make 400-500 hp but they are able to make 1800 ft lbs of torque. The inline 6 turbocharged combo is elite.
Interesting ... 🤔
Truely makes me wonder why there are not Diesel hybrids
😢yup
"Somebody might do donuts in the parking lot for 3 hours" LOL
Me : lives in a JDM country
everyone: 2JZ SUPRA 2JZ SUPRA
me : wait they didn't get the rest of cars that got the 2jZ?
*laughs in Aristo*
The Aristo is in the vid. It had it first after all
@Brett Collins ¿... You mad, bro. Who which knows about the engine would be in disbelief at who?

Isn't this the engine Beyonce married? I'm pretty sure it is. (Edit. I SWEAR I wrote this comment before 0:55!)
So Beyonce has two husbands?
i think it is the 2nd engine she married
Excuse me but what
This really is the best engine mechanics and engineering channel on the entire web, let alone RUclips. Every video is packed full of great information and I learn a ton of theoretical and practical information from each, and everything is clearly explained and easy to understand. Huge thanks, D4A, for all your hard work and effort on this channel! Can anyone tell me if the 2JZ engine is an interference type engine or free running/non-interference type? QUESTION ANSWERED @ 21:00! That is WHY this channel is so damned amazing!
This guy does a great job. This Transylvanian would make Dracula proud.
2jz is a non-interference engine
To everyone reading this, have a great day cheers!
You too 😊
And to you as well!
I hope you all have such a nice day as me,

Not a JDM guy but this is very interesting as its something I've always wanted to know.. This channel needs MORE exposure. Content is absolutely the best I've seen. Everyone should share this with at least one car friend...
Yes my man. I see you finally did it. This is the one I've been waiting for. I never get tired of watching videos about these engines. I'm currently swapping one into an 1991 MA70, so whenever I can find educational videos such as this it is always a chance to learn something new.
One of the best vids on the 2JZ, next please do a proper breakdown on the BARRA. We have one in Australia producing 2200hp on standard block, can't wait to see how these go with more R&D in years to come. Mass produced and available from basically every wrecker yard around, excellent base to start with
It needs American r&d to really get unlocked
@@Realtime1501 Yes there isn't a huge amount of people out there pushing and developing this engine to the limits only because it's tied down to one country. America desperately needs a few shipping containers full of them to unleash lol. There is a 6sec destroked version here as well that spins to 10k RPM, plenty of work involved with factory block. Maxx Performance seem to be one of the leaders in RD at the moment
Barras are shit
@@alanmansour477 they blow up at 8 thousand rpm there design and shit engineering.its a shit platform.stop trying to hype a turd up.its not even in the same universe as the 2jz get off the drugs
Had one when I was 18 and treated it like S. Still mad at myself. Thanks for the content 👍
Great video, love the Iconic Engine series. I'd also love to see the RB25 and RB26 engines get an in-depth video!
For the past year one regular russian drifter destroyed 5 rb25det, and only one jz!!!!
And good luck finding rb that will not destroy itself after 15 seconds in redline/cutoff
@@dren4k What you say is true, but I'd still like to see it get a D4A video. RB engines had plenty of success in racing, even if drifting has exposed the oiling weakness.
Keep up the good work man. One of the best auto focused shows on RUclips.
That demonstration is as beefy n worthy as the 2JZ itself !!!!
Fab .
Thank you for going one step further than most others, the level of detail is excellent!
Your video has has encouraged me to take my RZ-S A80 for a drive before it runs out of registration in two days time
This is absolutely the best auto focused youtube channel. I am a car enthusiast and the content here is way much easy to understand than sitting behind a desk. Thank you so much D4A. I would also like you to do me a favor of making a video about the Toyota Landcruiser 1HZ engine. Its Pretty popular and much praised where i live.
Without having watched the thing ima smack that like button , this gonna be epic for sure!
Wow man, another great video! I am so happy to disvovered your channel couples mounth before ;)
Great video. I learned alot. The description of the compound turbos is backwards thought. Air enters from the air filter to the large charger (primary) then into the smaller charger (secondary) then into the engine. It seems backwards on first thought. Using pressure ratios to increase the air into the engine. It would not work with a small charger first into a large charger because the small charger would restrict the big charger creating a restriction instead of increased air flow. Very common in diesel engines. Would love if you did a video on the 12v Cummins, which I had a compound setup on. Keep it up
I have been waiting for this video!! I knew you’d make it eventually, thanks man keep up the good work 👌
Another comprehensive and entertaining video. 👍🇺🇲. Nice job and thank you!
I read somewhere also that the engine is so strong because it was designed to be a turbo diesel, and it's design is coming from a copy of the Mercedes diesel inline 6, that Toyota first put into a small truck in the 70s.
That answered all my questions , and a lot more. Excellent work. Thanks.
Yes, finally my favorite series is back.
basically what I learned:
You gotta be thicc to make more power
Badass intro. I approve of this message! I was 2 years old when the first Supra came out lol
please do more of these videos like this, in depth explaining engines and all.
always great content. Maybe the Busso engine can also be considered an Iconic Engine for a future episode.
that intro was absolutely epic, Im pumped already and im like 30 seconds in hahaha
Thanks! Excellent video and the yards 3 cylinder video was great also. I'm happy 😊 to support your work !!!
Thank you! Much appreciated!
Excellent video on the 2JZ nice work!! 😎
The retun holes being further from the main cylinder shells also makes the oil return to the crank shaft a few degrees cooler.
Steve from Annapolis Maryland keep up the good work you got my vote you make me laugh you got a good sense of humor you're very intelligent you're really know your stuff about engines and I've been working on engines for over 30 years keep up the good work kid
Had 3 2jz-ge at 150k and all needed new head gasket. Iron to aluminum is the only weak spot. Love this video and watching more of this channel ASAP.
i subbed.. i love people that know what they are talking bout.. im new to these cars...and just bought a 280Z..thank you
I learned. Great presentation and very informative. Thanks for sharing!
Best auto mechanical channel on youtube! Great content
I just stumbled across this channel, and this content is fantastic! Subscribed!!
Intro was awesome lol!! Well done sir
That was awesome information bro 👍🏾 great video
Another awesome video! What are your thoughts on the 2tc, 2tg, and 3tc? The T series engines have good history. Guys in Puerto Rico have been pumping those engines for decades. Keep up the good work!
love how you give a real edcation on the history
The 7M got more reinforcement after 1990, and a much more balanced crank resulting in a lower redline (6500 vs 6250). The 7MGE and 2JZGE are much more similar than you realize. I ran my 2JZGE off complete 7MGE electronics in my 92 MKIII with zero issues.
I kinda went looking for this comment before remarking similarly. I haven't owned a 7m or 2J, but have torn a few of each completely down and own a mkii with a 5mge - the iterative development is very evident. It's crazy to say, but the roots of the 2jz go back to the first M engine in the 2000GT - Toyota and Yamaha had it right basically from the beginning.
Really good stuff man! Dropping a comment to help out the algorithm.
Loving your videos because they are educational, well made and enjoyable.
Please do the VQ35DE !!!
Love this channel and especially this series. I also love that he you did the "3JZ" before you did the 2JZ 😆
The ending rap 👌🏽😂, great video!!
Epic intro! Been waiting on this one and what you come up with
Fantastic video. Thank you for all the info.
Really good video and great explanation of the Mark IV heart. Learned quite a bit. End of the vid just cracked me up. LMAO
A really cool engine I'd love to see is the Toyota 22r, and 22re. I'd love to see a great explanation of the engine. Love this series btw.
I love ur rapping man🤜🤛🍻 thank you for ur efforts to make us folks more literate in this sphere.
What I still don't really get is the demands on swapping a 2jz into a new supra. As far as I know, the b58 engine weighs almost 3 times less than a 2jz.
best day ever once again thank you man you are the best
This is the kind of online history class I like
Man, I LOVE you work!
First class review and love the graphics
I recently found your videos and have really enjoyed them (plus looking at the back catalogue. Always a bonus of finding a new channel)
One comment i have is the audio is often echoey from the room you are in. Have you considered throwing some pillows against the wall in front of you while you record?
Anyway all the best! Keep it up 👍
Sadly it is a bit echoey. I did buy a new NTG2 from rode but I can't get it to work. I haven't tried pillows but I'm in the process of getting some foam and gluing it on the wall or something.
Dude, you are a hero! Love the rap :-) Greetz from Holland!
Best video on 2jz ever thanks yo...
Well put together! Not all engines are created equal.
Awesome video bro....could u do an episode on the FA-20?
Fantastic as always!
Been waiting for this one. I only learned about the 2jZed after I bought my 1986 Grand National. Someone said something about a comparison between the LC2 motor, 109 block, in the Grand National and the 2jzed. The first comment was, there's no comparison. The block in the Grand National is straight up a junk pushrod v6 block. Pretty crazy that a car with the reputation of the Grand National, heart is nothing more than a late 70's design off-center v6. The person did say though, it's an apples to oranges comparison. One is a v6 and the other is an i6. The i6 is a naturally balanced engine, meaning is doesn't have to deal with the primary and secondary engine harmonics like the v6, therefore can rev higher. The v6 bulk heads or main saddles are not beefy at all and this can lead to the main saddles cracking around the main bolt hole at higher RPM. Whereas the 2jzed has very beefy main saddles along with 7 main caps, as opposed to the 4 main caps found on the 109 block. This was one of the main reasons the 2jzed block is so superior, 7 main caps to absorb the load. Then the 109 is a pushrod v6 and the 2jzed is DOHC. I'm not sure if the 2jzed has aluminum heads or not, but the LC2 has cast iron and even with a full port job they don't flow that great. I won't say it's nothing to get 1000whp out of a 2jzed, but it takes every trick in the book to get a 1000 whp out of a 109 block. Try and take it any further and the block will split. Some 109 blocks have split 600 whp. Block wasn't designed to survive above 500 crank hp. To boot, a 2jzed block is lighter. So Toyota did a great job with the design of the 2jzed. Love seeing a 3.0L engine out performing monster displacement ci motors.
Top class video. What an engine it is!
It's just Insanity!!!
Great video, thanks. 😊
My favorite is the GR series of engines. I wish the aftermarket would grab this series and we could see more of these in off-road and race builds. 1 and 2GR as RWD street rods is possible.
I saw a video of a 2GR swapped MR2 that was faster than any other V6 on the hillclimb, even AWD. Very underrated engine and in a car that lightweight it's an absolute monster.
Great video! Can't wait to get me some of those supertactile pistons;-)
I remember when the Supra came out that much praise was given to another new distinguishing feature, its compound projector headlights.
Good rap at the end. Sums the 2JZ up 👏🏻
I've always thought about swapping one of these into my Jeep as it has a Toyota transmission in it. How about a video on the AMC 4.0 that XJ and other Jeeps have? It's a bulletproof torque machine!
Best Engine Channel 🤓🙏😎 By far 👏👏👏👍
Another video highlighting the fact I got the wrong Toyota.. and still the wrong engine in that car... but great content! Love it.
Least you didn't get a hybrid 😂.

what an episode... omg. Ty man!!!
At 23:00, that Supra is being driven in Tempe, Arizona! (aka Phoenix) :) My hometown! I had 2 Supras and an MR2 when I lived there. Great video!
Enjoying the videos,many thanks but... Porsche did the oil gallery cooled pistons in the 935/78 Moby Dick (1978) by making them in 2 halves and electron beam welding them together. Keep up the great videos!
Great videos- articulate humor and expert knowledge. Sub’d
i fucking love you bro, check my subscription date, I've been here since you started making videos on your mr2 engine and the diff between the blue and the black top, I wish you all the best and even tho this is different content but im honestly enjoying it even tho i know all of this information already... i just love the way you display yourself, Great path you set yourself onto btw, I know when the channel grows even more you'll go back onto project cars which is the thing im most excited and waiting for cause ik under that new man bun theres alot of crazy and new ideas.
This channel will be the encyclopedia of vehicles and engine in the next 10 years.
Imagine if Toyota had taken the 2JZ design concepts, and made an N/A V12 for an off shoot halo car stable mate to the Supra. It would have been the best, most reliable V12 ever. And so fun.
It could've have radical styling. And be the flamboyant competitor to the NSX.
Great quality video!
Amazing video! Thank you
As Always a great video
Thank you!
Dude. I f*cking love this video. The most in depth and best reviews of engines. Please for the love of god do the B58 in the new Supra. Or whatever is suppose to be BMW’s “2JZ replacement.”
7:15 here is a little mistake in the graphic or in what you are saying.
The graphic says the old MK3 is 100kg lighter and you are saying that the new MK4 is 100kg lighter.
It’s an amazing video and I learned so much!
I’m an engineer from Germany who works in the development department for one of the big car companies in Germany and I’m just learning about the details in Japanese cars and engines and your videos are really detailed I like them a lot!
I know a lot about BMW, Mercedes, Porsche, Audi and Volkswagen engines but not much about the Japanese engines besides their name, layout and cam position.
Supra, a prefix. Toyota, adds it as a suffix. lol. Great video as always, sir!
0:03 IS THAT A SUPRA?
The best part of the video was the rap at the end! Lol jk. Great informative video! The 2JZ is truly one of the best engines ever.
Hey will you do an episode about awd conversions (and other conversion topics), specifically for toyota? Grazi homie
What a legend =)
Engine is also awesome
Lol.. Thanks for the content.. Loving it
EPIC intro!
I guess it's a good engine. Maybe I can put one in a Civic. Kidding. Thanks for the informative and slightly crazy video.
The best inline six ever produced for a modern production road car, hands down.
I agree and I've had 2jzs for 16 yrs but I recently picked up a bmw z4m and the s54 I6 is a great engine too
I’m not so convinced. Bmw in-line 6s are also pretty damn good and the new one (b58 I believe?) is already hitting some crazy numbers very early in its life.
Great Video!
