Ok I havnt really seen them but can you run turbo on a carb setup? If possible is it more expensive than a efi setup?
Yes its possible. Need a "blow through" carb. If you can fabricate yourself, wouldnt be all that expensive, if your paying for all the work, its gonna add up. Would recommend at the vary least a full rebuild with ARP studs and possibly metal headgasket to ensure reliability. But if your gonna spend the time and money, build it right, and look into forged. Been in the boost game (supras) for a long time and building it right the first time is definitely the way to go.
