'Ixixly' that's the exact reason why more so called modern engine types/designs aren't flourishing in the outback, too complex, nothing like simplicity when yr out there in the bush with just bush parts & bush Mech's about.

These sorts of power-plants have their uses for sure as DOD etc but doubt very much it will be in the front of an old crusty 206 anytime soon.
