differnts between the stock 03 wrx and the STi ver. 7 S202/Spec C Cams what is the power hold for each of them. then I would like to know what cams you would recamend to go with if I chose to go with after market cams. I'm looking for something to hold at least up to 320-450whp.
The spec C cams are way better. They don't choke at higher rpms. It gives a lot more topend power. Especially if you paired it up with a raised redlin, springs and retainers, and a turbo that'll actually hold boost to redline.
