Does anyone know if the manifold in a turbo kit for a V6 E36 work on a V6 E46?  One person told me no and he wanted to charge me an additonal $400.  Everyone else I talked to told me yes and that he's just trying to get more money. Does anyone know?  I was told as long as my car is not an M3 (which it's not), than I can use the same kit.  HELP!
