Changes to a N/A Supra to increase performance

I know what extractors are (Oh, nevermind, I didn't see that it was asked)... I don't know that they'll net you much improvement though... The 2JZ head flows much better than the 7M's so I'd expect a gain higher than the 10HP or so that N/A 7M owners claim, but I don't know if it would be enough to really be worth it. Try searching for results using the term "headers" instead, it will get more hits.

Other mods I would consider would be replacing the exhaust piping with mandrel bent piping with fewer bends if possible; Replacing muffler and resonator with free flowing ones; And swapping in a free flowing cat. Then, I'd move on to upgraded cams; Weight reduction. These are pretty much standard upgrades for N/A, my 2JZ GE knowledge is very limited though, so I can't advise beyond this.

I didn't know that about licensing in AussieLand... It makes sense to me. I wish they'd do qualification based licensing here in the states... you test for certain grade of license and based on your actual ability you get a different license and plates that reflect precisely how fast you're allowed to drive and where. I also think they need to require actualy behind the wheel driving tests every 5 years or so instead of just ONCE.

So where else does the 2JZ-GE generally need help? I'd like to know more too.
