ok ..
so I dropped in the "mock up" engine , and tranny .
as suspected .. I have to cut the firewall . this is all going to work out great .. now with cutting the firewall , I have to move the pedals , and with that, the seats .. which actually works out excellent .. the tranny shifter is now *exactly where it should be .. nice , I'm stoked .
also added the exhaust manifold , and turbo .. to see how much modification on the down pipe I would have to do .. just SICK .. I dont think I have to do any .. it fits the crossmember , and "new" firewall excellent ..
