Since this site contains so many mechanically knowledgeable people I thought I would ask here.
I was looking at a 4.2 installation into a Porsche Cayman tonight. The owner had a blown up mock up 4.2 out of a 2000 A8. Purchased a 2002 S6 4.2 for the real motor. The 2002 S6 bolted up to the trans were the 2000 was a different pattern all together. Only some holes matched up.
Other than the RS6, I thought all other 4.2 (belt drive) were the same block, how far off am I ???
With all the early Porsche watercooled M96 motors going south this is a great alternative that many owners are contemplating. Would suck to buy a motor only to find it does not fit up like the S6 motor did.
Do I also understand that the V10 and W12 share the same bolt pattern as the RS6 ? Guess that means that Steve K's adapter will work with them.
