I have an LS. Does a porting and polishing of the head do anything to weaken it when a turbo is in place? I'm pretty sure it doesn't but I'd rather be safe.
What would be your recommendations to switch out as far as internals go, if I wanted to put some stronger stuff in on the parts that are more likely to break sooner.
I'm thinking pistons and valve springs, and what about valves? I'm also gonna change out the head gasket also.
And also, what turbo setup would you recommend, as far as companies?
As far as engine build up, I'm got a Centerforce dual friction clutch and lightweight flywheel, which I've had for about a year and a half because I knew I'd be going FI one of these days.
Other than that the internals are still stock. Also, I've got a Greddy SP exhaust, which is I believe 2.5 inches......do you know to what PSI this will put the boost at? I really don't wanna go any higher than about 7 or 8 PSI.
