You would need a good tune you would need the heads you need the lower intake manifold you need the supercharger you need the PCM but you can't just run a stock PCM you would end up blowing your motor up you have to have somebody tune it with a specific tune for you. Me and another guy on here with a Impala that's heavily modified can beat stock supercharged cars your best bet is to run your n/a setup but from a 04 or newer and run a turbo if you really want Power but if you're going to go that route you're going to want to run a supercharged bottom end because compression. It's all in money and route you want to go. I'm trying hit 300hp on a n/a set up that's my goal
