Just curious, since the Turbo oil = gallery is pressure-fed with oil, why would it need a gravity-induced oil = return? Would the oil not just pressure-feed back to the sump with the residual = pressure when running and the oil return’s routing prevent the sump oil from = running back?

  A turbo you may look into is an Airdyne, it has its own oiling and doesn't require oil from the engine.

 I use these on snowmobiles as they have no oil.

 Another advantage of these is that in the event of a turbo bearing or seal = failure it would not drain your crank case.
