I think that exhaust manifold was also used on early 930's but had another connecting bracket for the actual exhaust pipe. On the 1200's isn't there a plate connecting the two to the turbo. Never looked at them that close but sure looks like the early manifolds. Hopefully I got this picture to load. It is from the photos here on the board. Look at this exhaust. It is centered not up front like the later ones. Rod email is open would like info on the turbo if there are no other takers.
