Try opening up the exhaust with a set of headers or Ported exhaust manifolds. Then do a u-bend delete to get good flow. A cold air intake is always a good bet since it allows more air into the engine. This will get you started. If you want hard core then you will need some engine mods like new cam, bigger injectors, reprogrammed PCM and etc. Start small and see where you want to go from there.
