What is a reasonable gain of HP not installing a turbo, but instead installing racing cams and piston heads?

 

very low, I would say no more that 190HP. 200 Tops.
its easier to turbo cheap for a grand, thats wat I would do. need to know how to weld though (basic).

 

"racing cams" are only give you a power gain in the high RPM range ... so you will need to actualy race to feel the benifit of a "racing cam"[sm=badidea.gif] they are useless for drivind to work, school, store and such

 

other way round mate the cams and pistons give the power throughout the range the turbo give better power up the range but saying that why not do both

 

and a port and polish wont go amiss if you striped it all down
