Help me choose a turbo for rear mount Hello, I'm looking for a turbo to replace the 67mm turbo that comes with the STS kit. My car has a 212/218 .555/.555 115 lsa cam, ported 241s (compression ratio is around 11:1), and ls6 intake. For the turbo build, I plan on running 100% e85 and a FMIC. I also have a meth injection kit ready if needed. The fuel system will be stock lines, stock rails, 80 or 90lb injectors, twin 460lph Walbros in tank. I am going to heat wrap the entire exhaust side to help spool time and the e85 should help too. I was thinking of getting something like a ball bearing 76mm .81ar from on3performance. Is this too large of a turbo for my setup? My goal is 580rwhp on 10psi. Any other suggestions?
