I know you said you researched it, but this gives you a good visual and a good idea what you'll be getting into. What i remember he is doing it on a 2+2, because 2+2's dont' come available turbo charged.
BTW that sounds like its gonna be an awesome project and sounds like you might be able to have a hot car for a whole lot less than it should be.
