Ok I have a few questions here... my friend whos doing my swap said that I couldn't swap a Z6 in because there is a sensor (?) near the crankshaft that, once done, the car won't start or run. What the fuck is he talking about? Will this configuration work? D16Z6 block w/D16Y8 Head? What do I need to swap a Z6 in place of a Y8????? Please this is urgent. He told me to dig up information on it and I am supposed to get the engine today.
