the f-series compression is better for turbo than the h22, but remember that a f22 at 7psi cant keep up with the h22 with 7psi. unless you wanna build the internals i wouldnt go past that much anyway. i would go h+turbo if you have the money, personally i like the f-series turbo'd
or just buy an s2k and turbo that beeyatch

 

h22+nos?

 

heh, no juice for me! can i boost to 7psi on a completely stock f22? if so, that alone would make my car faster, right?
