IMO it would be retarded to TT a 4 cyl. BUT thats only because i would never do something that isnt effiecent. A TT 4 cyl wouldn't be any better then a Single turbo, acctually the money your going to spend on 2 turbos would be a fully built motor that its like 300+ hp easy.
but then agian
It would be like pimp factor 9. i mean a TT accord? only for shows it would be pretty cool
but for speed, it would be retarded.

lol, either way, if you do it, i wanna see it
