Quick Question...What is a common Turbo that would't cause alot of lag and that would have decent spool time that would be a direct bolt on to my stock turbo manifold? I have a friend that has a ct27 and a ct20b, $150.00 for ct27 and $100 for the ct20b, came off a 3rd gen 3sgte..Decent sized/bigger turbo? or go with somthing else?
