I have the article that SCC(I think it was SCC) did on this. I'll have to look at it again. They also did a series of articles on turbos that is supposed to explain alot. Anyone read them? Would it be worth my time to look them up?

Oh yeah, The ITR engine is out the window. Too expensive to build NA and would be rediculous to get an ITR motor and turbo it, again way to expensive for me.
