2JZ ENGINE - How it Works | SCIENCE GARAGE 

We know we can't include everything... let us know what YOU love about the 2JZ!

Just think about how reliable this engine is when you keep it stock

"How the 2jz works" Easy. Gas goes in. Happiness comes out.

Man... I wish the Fast & Furious franchise went back to cars, tuning and customization...

I've had a stock 2jz in my 240 and its driven me over 680,000 miles I've keep up the maintenance and it's still running strong

UR like is the engine you r gonna have- 1- 2JZ 2- RB26 3- 13b 4- 4AGE 5- LS 7 6- EJ25 7- B16 8- K20 9- K24 0- 4G63

Toyota: Lets remake the Supra but let BMW manufacture the engine. Everyone else: Let’s 2J swap the new Supra

"2jz swap everything" suddenly a 2jz lawnmower appears

1:25 "speed doesn't hurt, it's the sudden stops that get you" - Jeremy Clarkson 😂😂😂

I know the biggest secret of the 2JZ engine. It's made from melted down samurai swords LOL

Inventor: How much HP you want? 2jz: Yes.

Science garage is by far one of my favorite series on Donut. I'm somewhat new to cars and science garage and donut overall have played a huge roll in my journey into cars.

Toyota also over engineered the 94 Celica. I have three hundred and thirty five thousand miles on mine. Scotty Kilmer Special

Speed isnt the problem, its the sudden stop that gets you. THATS DARK Quote jeremy clarkson

Toyota should remanufacture brand new 2JZ engines like americans do with crate engines

The coding system works simply: the first numeric character(s) represents the engine block's generation, the next one or two letters are the engine family, and the suffix, separated by a dash, lists the engine's features. For example, a 2GR-FE engine (used in the Avalon, RX 350, and Highlander) is a second-generation (2) engine in the GR-series featuring an economy narrow-angle valve direct overhead cam (F) with electronic fuel injection (E). The suffixes for Toyota engine naming are as follows: A - Valvematic variable lift intake head B - Twin SU-style side-draft carburetors (After 2000, 'B' indicates capability for E85 Ethanol) C - Carburated / California Emissions Controlled D - Twin Downdraft carburetors E - Electronic Fuel injection F - Economy narrow-angle valve DOHC G - Performance wide-angle valve DOHC H - High compression, High-pressure charged I - Single-point fuel injection J - Autochoke in early models, unknown pollution control later L - Transverse M - Philippines' market N - CNG fuel P - LPG fuel R - Low Compression (uses 87 and below octane fuel) S - Swirl intake SE - D-4 Gasoline Direct Injection T - Turbocharged U - Japan-spec emissions w/ catalytic converter V - Common Rail Diesel Injection (D-4D) X - Atkinson cycle (most-used on hybrids) Z - Supercharged

we need science garage back

Brian: Pop the hood Dom: Pop the hood? Brian: Pop the hood!

Loved the upgrade from my NA to turbo Supra and the sequential turbos were something else when the second one kicked in. Eventually donated the twins to a friend and their Aristo. Currently runs around 600hp on stock internals with zero engine reliability issues.

Seen so manny 2jz videos on RU-vid and I had no idea what they were, couldn’t of asked for a better video to tell me. Great work!

2JZ is a thing of beauty. It's so beautiful, it almost makes me want to become a mechanical engineer.

So much Supra content across the platform lately!

"speed doesnt really hurt anyone, its the sudden stops that getcha" classic line

I was always curious about the car cultures obsession with the Supra, now I understand! Thank you for the great video!

Toyota: let's build a very reliable engine that will last for years *ends up being a tuners wetdream* Toyota; um sure...

Slaps a 2JZ on a Prius

"Speed doesn't really hurt its the sudden stops that get you" That's some wisdom right there

Missed meme opportunity having two faces of Jay-Z

So I owe a guy a 10 second car. Would this engine in a burnt out shell be a good idea?

my first ever video about this channel. and you know I'm already subscribed amazing way to relay information even for people who don't really understand it.

Honestly this channel has helped me out soo much!!! Thank you guys so much!!!

Why is Lance Armstrong telling me about 2JZ engines?

Beautiful explanation, very useful for people that are not specialists on motors and cars

this was the golden era donut

I 2JZ swapped my grandmas wheelchair

*Dear heavenly spitirt, thank you for providing us with the direct port nitrous injection, four core intercoolers, ball bearing turbos, and titanium valve springs. Amen*

Great explanation! Mine is almost done! Going for 7s!

This is so sad that Science garage is gone this was my favourite show... now I'm stuck watching reruns to get by in life.

1jz: I HAVE THE HORSEPOWER! 2jz:I GOT THE ANTILAG AND HORSES!

3JZ confirmed. Same as Half Life 3.

The more you explained the more i had to pick a tear realising how beatifully the engine is

Wow, well when you break it down like this it really makes me understand and appreciate why it gets the love it does. GG to Toyota for being all German and overengineering the crap out of the thing!

Please do crossplane vs flatplane engines?

I'm pretty sure that drag Supra with the tubbed rear end in the video had a 2JZ in it 😎

Glad to have you back on the show !

1105 rwhp / ~1300 crank hp is the current stock block record for the 2JZ. Did several dyno runs and 1/4 mile runs before it snapped a rod after letting off at the end of 4th gear from full boost to full vacuum. The shock snapped one of the rods.

I'm a simple dude..i see 2jz or supra. i click. Even if i drive a skyline.

RB26 2JZ 4G63 EJ22B 13B Are true love

Bring back this tipe of episodes and up to speed. Those were great

This is a flawlessly produced video.

People swapping new Supra's BMW engine to 2JZ in 3, 2, 1... Btw, Nissan RB series is a wonderfull engine too.

So now you’ll make an RB26DETT video right?

Simply its a perfect peace of art

I’ve learned more from this channel than all 12 years of school

3:47 overnight parts from japan🔥😂

Youre wrong GTE stands for Good Turbocharged Engine

Lots of awesome stuff I didn't know about the 2JZ! Seriously overdesigned and overbuilt for a factory stock street engine. But I believe the oil squirters were added primarily for piston cooling more than for piston lubrication, although I'm sure they help with that also. I'm no JDM expert and could be quite wrong. The "New Supra" is a BMW bastard. For many reasons, I don't think it will ever live up to the legendary Mark 4, but we will see! These are exciting times for auto performance! A bit like a 1960s renaissance :D Good video, thank you.

Nicely explained, good history.

7:31 Talk about 2JZ, show footage of Brian working on RB26DETT, gg.

Jay Z was the creator of the engine, why dont they ever give him credit...

man i missed this guy explaining things

The lag introduced by the installation of a bigger turbo is easily compensated for by adding a shot of nitrous during spool up to quickly ramp up the rpms until boost kicks in.

Man I really thank this channel for such in-depth episodes. Great job guys. Love your material

The 2JZ-GTE VVTi is non-interference, just like the non VVTi. The 2JZ-GE VVTi from the Lexus IS300 is an interference engine (because of the higher compression). Supra Stock long block record is 1043whp and 808tq with a GT47-80 running ethanol. 9 variants of JZ engines not 6.

Honestly I really like this guy and the way he talks, its smooth. I'd love to see more of him!

Awesome research solving answered

speed doesnt really hurt, its the sudden stops that get you. clarkson quote i guess

I love it, knew most of these points but was unaware that it was a non-interference engine. Such an amazing design, truly built by design to push far beyond its original specifications.

I like how this is explained so casually, this is my favorite Donut show because it's not over the top, JAMES

I miss this man

A thousand reliable horsepower you say =2JZ

4G63 next!

I like to think I know a lot about motors in general, but your videos always teach me something. Great content guys

One of the best series y'all skulls bring him back

Another solid video, guys. Thank you for all the work you put in

Lvl 1 crook RB26DETT engine Lvl 35 boss 2JZ thats how mafia works

Love my 2jz. Even if it is a Ge motor. I've had a timing belt tensioner snap it's bolts on me... Yay to non interference!

I miss this guy, bring him back, please

It's an Amazing Engine. 2JZ-GE in my lexus. I want a 2jz-gte though.

the episode everyone didn't know they wanted. Cant say i learn too much on science garage, but i always enjoy watching the show

I just picked up an IS300 and this winter I’m going to build the engine and I can’t wait

Thank you so much for the information

3:18 you know when you watch too many supra videos when you know what video the audio is coming from

Supra Stock long block record is 1043whp and 808tq with a GT47-80 running ethanol

"Speed doesn't really hurt its the sudden stop that get ya"

Best episode of your show!! Get back to this style guys please

too bad the new supra wont be as legendary

Thank you so much for these videos! Please keep making them!!!

My uncle has a Supra rz in his barn and it’s in pristine condition and I’m so pumped to help him work on it

Cool presentation 👍

Way back when that engine was just coming on scene I remember the shop I used to frequent flowed and measured the airflow dynamics of the head and it was quite confusing.... naturally it didn’t hurt much because it’s forced induced but seeing the numbers were headscratching... If I remember the outer cylinders flowed way odd compared to the inners. But oh man that block density and thickness up top was amazing. The stock injector flow rates were quite impressive as well. No wonder why they became the monsters they are. That getrag trans was another badass piece.

Can you do a video explaining the Australian built Barra turbo engine please. This engine is bulletproof

This helped me a lot thanks

I don't think im at the right place to start learning about cars but i love it

Donut. Next up: N54 engine. The modern 2JZ

This is the best explanation about 2JZ I've ever watch so far

Now i understand the REP of Supra at technical level. Thanks

i hope they would make this engine again 🔥🔥🔥
