Everybody is going to tell you to do a "PI head/Cam/Intake swap" It is swapping in the top end from a 99-04 GT that basically gives us nPI owners a good 45hp. And since you can pick these parts up from a car yard, or auto salvage parts dealer, it can be pretty affordable considering the HP gains. I am planning on doing it myself.
If youre not looking to go that major of a route. Go with a Steeda Tri-Ax. I love mine. It is ridiculously precise.
I would also get 4.10 gears. I have 3.73's and they don't pull hard enough for my tastes. I am hoping that will change with my PI swap. I have full bolt ons by the way, so it isn't a dog by any means. But just quick, not FAST.
