your not gonna make much power at all NA and single cam on top of that.
better luck swapping in a ka24de and putting single cam pistons in it and doing head work to that, but then you will only make 200hp tops with a awesome tune and itb's.
you might wanna just throw a turbo kit together with a t28 and bolt on's..
how much power are you planning on making and what are you gonna use the car for???
