i need mods!

[ac97gt]

ok, i just got my car recently and i already want to start modding it! (of course ) ... i was hoping maybe you guys could point me in the right direction if i tell you my goal... which is to have a sharp looking smooth driving car putting out about 300-350hp N/A, but setup for maybe a supercharger and/or nos later on. the only things i have done are a flowmaster exhaust and the air intake silencer removed i have a bit to go .... the things im thinking i will get soon will be a new shifter (maybe a hurst) and new gears (~3.73), and a K&N filter... after these im stumped. i dont know a whole lot about engines but im willing to and want to learn. would i want to get some new heads and/or intake next? which engine mods will i need to achieve the 300-350hp? i just want to set some goals for myself so i can start to save up and know what im going to buy im sure everyone will have a different opinion, but all opinions are welcome! thanks.
