I have been looking and I really like the look of the 3.0Csi. On average, what can I expect to pay for a 3.0 with an average body (minor rust okay), and a blown engine. It is pretty evident that I am looking for a project car here. Is it possible to put the early M30 engine (like from a 1979 Euro 635) in a 3.0 CSi. I also have a dogleg tranny I might like to put in a 3.0 if it fits or can be modified.
