If you're happy with a 12 second range car (like me) standard bolt-ons (intake, exhaust, Cold air intake, manifold and a tune gets you there), then if you need more, get you some 4.08 gears and the LSD upgrade to help put it down). I'm at the point now where the next mod would probably be a LSD (My car doesn't have the sport package) and the gears to finish it off.

just my opinion though...
