well ive been thinking about adding some more power, and am wondering what everyones opinion on the JDM stage 3 kit are, the price doesnt seem too bad at all for what you get, but what about the performance gain?, how noticeable is it?

I had the Saleen 475hp Kit and upgraded to the 3.4 pulley, 107.5 Gates belt, Saleen Extreme Intake, Vacuum Line Kit and JDM Tune. It was a drastic Seat of the pants differance. Easily a 50hp gain. I was able to break into the 11.9 sec range in the quarter mile which isn't bad considering my car weighed 4050 lbs (it's a convertible).
Well worth the $900 for the upgrade.
Good luck,
Al

If you are planning more than 10 psi I would recomend a forged rotating assembly. Otherwise 3.4 pulley is the most I would go. I know people that have done the 3.2 pulley on the stock bottom end but that is pushing your luck.
Also at anything above 450 rw.hp you will need either a boost a pump or a dual pump or you will be running lean on the top end.
Good luck,
Al
