I have to put a new engine in my 1993 190E 2.6 automatic. (This is a
U.S. car.) Someone suggested that I put a 3.0 in place of the original
2.6. Given that they are essentially the same engine, the suggestion
didn't sound bad.

Is this feasible, and, if so, is there any particular 3.0 that would be
best? Any pitfalls?

Suggest you focus on engines that are the same model year as your 190E
so the electronics and emissions controls will be as close to those of
the dead 2.6L motor as possible.

Yes, that was my concern also--thanks for the feedback.

There have been several successful transplants of the M103 3.0 and M104
twincam into the W201 2.6 engine bay. They will bolt up to the 722.4 trans,
provided you have the ECU and wiring harness from the donor car.
