I havent read responses yet so this might have already been said. If you planning on Autoxing I would choose, neither. It bumps you to a much more competitive class that you wont be able to compete in and Autox is more about suspension.
If you must FI go with a supercharger. Once the turbo starts to spool you will have to start breaking rendering that power useless. Ive seen this happen to most of the turboed cars out there. The Supercharged ones dont have that boost of power all at once. They have it where they need it.
So I guess I disagree with all that say turbo. I havent seen any proof that turbos are anybetter
