Without doing anything radical, get a reprogrammer first, then a cold air kit, free flow exhaust, then if you want more you can always go supercharger or turbocharging, but be careful with the boost, or you'll fry it for sure. Or if your into spending big bucks, pull the engine and have it modded meet your needs, you could even go Nitrious injection, but don't forget the tranny as it will need beefing up too. Once you start it up to you on where to stop, engine, tranny, suspension, brakes, wheels, tires.
