stage 2 cams from skunk2 will make more power if you increased compression.
so you get new pistons to increase compression. granted you'll make more power.
in all honesty. locate a used turbo kit in good shape buy it, slap it on and buy hondata with boost option. run like 8 psi of boost. and have it tuned.
i feel it's quite reliable. and you'll not only make much more power than you would with a pair of cams, but you'll also flatten out your power curve making more power for a longer period of time.
it's personal preference.
