So i have been researching through previous posts, and i cant seem to find exactly what i am looking for. I am wanting to get about 600-650hp at around 25-28psi with water/meth injection, forged rods, pistons +.020, completely ported ect., 750cc rc's, ffim, 90mm throttlebody, 3in. turbo back, 2.5in hotside and 3in cold hardpipes, and maft-pro; w/afr and boost control. Keep in mind staying 8.4-8.9:1cr. I am wanting a quick spool though, obviously a bb would be best, hopefully starting boost around 3000rpm or lower and running full boost by about 4000-4200rpms. i am looking at the sp67gtbb, still unsure about exhaust manifold though? i am having a hard time matching up the turbo to manifold terminology. any suggestions and help would be greatly appreciated!!
