ok so i want 2 gain some horse pwr by adding crower stage 2 3/4 race cams and then getting the port and polish done and adding bigger injectors and then even adding the 255 f/p and also adding the 55mm t/b so im wondering if thats a good set up or should i go for the stage 3 full race. and im wondering wats it goin to d seeing how i wont have the turbo on it the stage 2 is for nitrous and aggressive street an 3 is turbo and heavy engine mod does anybody use the stage 2 and like what they got out of them and how noticeable was the performance gain if any from the stage 2 cams im looking for more in the low and top end

IMO I would skip the head work and go turbo. The 420a head has plenty of flow for your needs.

2.4L block, highcomp long-rod forged internals, crower 2 NA grind, MSnS, 60mm tb, quicksilver99 True Header, and 2.5" exhaust.

truly, unless your trying to be unique and have money burning a similar hole as the desire to remain NA, buy a turbo and have fun with your car.
