You would need a full exhaust system so you can get the car to breathe better. With a Magnaflow Cat-back you should see about 7-10hp gain because its a straight though muffler. ( http://www.magnaflow.com/01home.htm )

Then you would want a different gear because you would need to get up to your power-band faster.

I also seen that the Densecharger ( http://www.densecharger.com/ ) would give a fair power increase.

Pulleys are good for a few extra ponies. ( http://www.steeda.com/ or http://www.marchperformance.com/ )

A bigger mass-air would help too. ( http://www.pro-flow.com/ )

Finally, the last thing you should do is get a chip once your done putting parts on the car. ( http://www.jmschip.com/ )

Good Luck
