Well how much do you want to spend? I can think of hundreds of different combinations of power adders. First thing's first...start with true dual exhaust. If you have the money, put a Vortech supercharger kit on there like my car...You can buy my engine and blower with computer for 2 grand. Your car and my car has the same engine and bay so it would be an easy swap. If that is out of your price range, id say a superchip or hypertech chip in it with a tranny kit if its auto, or a nice clutch and short throw shifter if its manual. Id also consider getting an 8.8 or 9" rear end. Mine has an 8.8 and its just fine. You can do head porting, intake porting, head shaving, a cam, injectors, under drive pulley, valves... I mean there is a number of things you can do. The real question is, how deep are your pockets?
