I don't recall mentioning automotive at all, although most of the (truly) available aero diesels are heavily automotive based.

You could, but the engine would be much larger than required to make the power, especially if you're still paying the weight and complication penalty of having a turbocharger hanging off the side of it. A big engine is a heavy engine, especially when the high cylinder pressures of diesel engines are concerned.

The SMA and Continental CD200/TD300 are air/oil-cooled. The rest tend to be liquid cooled (and thermostatically controlled)
