I looked at the Flyeco site this looks like a great choice from some of the very old design small continental and Lycoming engines designed in the 40's Mercedes Benz has a history of building good diesel engines of what I'd call medium duty and light heavy duty engines and as long as the people using them remember that these where designed as car engines not heavy duty commercial/industrial engines they should have great success with them .. You are not going to start pushing turbo boost like the heavy duty engines run example the C-!5 Cat twin turbo runs 45 to 55 PSI boost and most other heavy duty diesels use no waste gate or boost limiters plus they usualy have much larger cooling jackets around the cylinders (hence there very slow engine warm ups) Back to boost given same fuel flows increased boost will usually lower cylinder temps. on diesel engines and give cleaner combustion diesel enginesin some ways act different than gasoline engines and to people who decide to use them need to learn diesel and they should have good success with them..
