Yes it has the PI heads & intake, all 99-04 untouched models. I don't believe it has forged pistons, not 100% sure.

TT im not sure how may pounds of boost it is, but it all depends on you setup ie: heads/cams

with 400rwhp you will be deep in the 12's, if not better........

centifigals are only in boost when floored at 3500 rpm's. However I did the recommended fuel injector, fuel pump upgrade, tune, etc and I'm getting 10mpg and using 93oct. Also the blower&installation is quite expensive unless you have a friend that can help you. Good luck with your GT. Enjoy. Stay safe.

There is another thread going on right now in talk, about how much HP the stock 2v bottom end can handle and the 400 mark isn't really correct as long as the tune on the car is spot on. Hotmustang331 had a gt that was making (i think he said) over 500 hp with his turbo setup. A centri blower will also be less stressful on the motor

You're safe with around 400RWHP. Tuning and fuel is the most important thing to a long living supercharged motor. As long as it is detonation free, it will live forever. I would add a nice Vortec S-trim with about 8-10lbs. If you want more HP, like 450-500RWHP, add methanol injection, 14lbs of boost and premium fuel.
