I just want to clarify some things for myself and other people on the forums (with your help). While achieving higher horse power were major problems occur.

1. Sock TT setup is good for 320whp with some modifications (Exhaust,Boost controllers, intercooler, etc.) you can achieve aprox 480whp before TT’s are maxed out and you are leaning out.
2. Between 480whp and 700whp you have larger turbo(s), more fuel, increased cooling, clutch, etc.
3. Between 700whp and 850whp you are pushing your top end capabilities and your rods
4. 850whp+ seams to be a hole other ballpark you are changing rods, porting heads major engine cooling, stabilizing drivetrain, etc.

I realize I am being very broad but I want like to know where your major stock components fail i.e. drivetrain, block, rods, pistons, crank, cams, cooling, frame tweak, etc.

I would say swap the whp to flywheel hp and your numbers are about right

Has that ever happened on a 2jz? I would love to see the pics

Ive heard many times 1000hp+ on stock bottom end.. the 2jz is simply a de-tuned race engine.

Yes the 2jz block has cracked on several occasions. Never seen one below 1200whp though.

Yeah, well people tend to say all kinds of crap

1000whp on a stock 2jz bottom end is a disaster waiting to happen!

really I'd like to read up on the history of the 2jz motor.

No way, those numbers are dead on.

I agree, I thought he summed it up well.

I too was interested in that. Sofar, all I could find was this little snippet from Wikipedia:

"The 2JZ-GTE is an inline-layout, six-cylinder, belt-driven dual-overhead camshaft, air-intercooled, twin-turbocharged, cast-iron engine designed and manufactured by Toyota Motor Corporation that was produced from 1991 until 2002 in Japan. Final development of the 2JZ-GTE was outsourced to German engineering firm Johann A. Krause Maschinenfabrik GmbH for refinement to meet production car homogolation requirements set forth by the former All-Japan Grand Touring Car Championship."


Interestingly "Johann A. Krause Maschinenfabrik GmBH" is:

Looks like they're a division of the German company ThyssenKrupp:

Rest assured, the 2JZ had some of the best minds working on it


Thanks,

It's a very impressive motor I don't know a whole lot of cars that can handle 700rwhp on stock internals.

 

[MissSupra]

1000whp on ANY motor, built or not, is a ticking bomb.:blast:

Not a Veyron.

Not a Veyron.

Let's be honest technically that motor is "built"

I think many people on this forum would beg to differ with you!
