your going to get about 20 different answers. for the ring gap, i would contact the manufacturer. the bearings... right around .002 to .0023 would suffice. i like to run a tad tigher than that, but i am pickyier than most.

goin on the cheaper side probably master power. but i dunno whether to get a t70 or 76 and what exhaust housing for my setup. i know i gotta weird setup trying to run flat top pistons, but then again i only want 600 - 650 hp and i need it to be a street killer

for the turbo i would select TC78 at 12psi with stock piston and you will be at 700rwhp

Im running a Master Power GT45 at 14 psi and 600rwhp. The MP70 will leave you wanting more. I agree on the TC78 or MP76 if you just cant spend the money like I couldnt.
