LOCKED cause this thread is not going anywhere. Flaming is not allowed. however, to the guy that started this:
you need to be on Club4Ag or something asking these questions. I persoanlly agree, why buy a high comp motor to just turbo it. Realize what you want to do FIRST, make a plan, call around an find out costs, then build a budget an a plan.
If your dead set on turbo, then i would get the 4aGZE supercharged engine. that shuold be better suited for turbo since it has a supercharger on it. I dont know alot about AE86s, so i wuold do ALOT of research an take what you learn with a grain of salt. im sure there are TONS of shops in the nation that mess with them, so give them a call for advice.
good luck
