Just realized you could convert a 2 stroke snowmobile engine to not require oil in the fuel.
1. Add a turbocharger so it gets forced induction while running
2. Add a small electric supercharger (e.g. leaf blower fan) for starting
3. Add an oil pump and switch to a drilled crankshaft and pressurized oil bearings
Leave the whole (tuned) intake / exhaust system intact, it needs to be re-tuned a little bit for the turbo, but that's just muffler design.
Would be an efficient way to get a lightweight experimental aircraft engine...
