This is a tough thread to follow! The W115 had fuel injected coupes (250CE and 280CE) and a Fuel injected sedan (280E) there was never a 250E.

Is the engine that is currently in the car a 2.3 four or 2.3 six? The W114's came with both. I remember talking to David Poole about a 280C to 280CE conversion using a K-Jetronic motor. He told me that he performed this sort of conversion and it required some cutting of the body (so be prepared).

If you can find a Euro 280E engine, this car will run like a bat out of hell. My 250CE was plenty fast enough.
