hi i need some help im goin to be getting the supercharger kit from raptor super chargers and was wondering in order to get more then 9psi its just get a smaller pulley? and ill need to change the pistons and rods? can i just get heads from a wrx or sti and put them on my car if so which years wuld be sufficent? and will i need to get a whole new exhaust setup/fuel pump/injectore if so what kind? any help would be great im not trying to make big power but i would like to have a lil more fun.
and i know i could just trade it in and get a wrx or sti but i really dont want to so thats in the bqack of my mind and my last resort
