Been thinking about replacing my tired M20 with a new upgraded power plant. I have noticed that there is a few companies out there that do this:
Korman, Bavarian Engine Exchange and Metric Mechanic to name a few. Does anyone know who makes the most dependable and powerful engine for my E34? I am looking for the most bang for my buck here. Anyone have any praises or horror stories about the above companies? Or is there one I missed that would be better? Thanks for your time.
