Honestly, If I get another DD, I am probably going to put a crap turbo setup on one of my GTP's just for the fun factor of having a turbo over a supercharger. After I put a cam, exhaust, smaller pulley on any of my GTP's I would probably only be a few bucks away from putting a turbo on it.... My advantage now is that I have a few turbos, intercoolers, hot pipes laying around to make the process fairly simple.
