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?

My main concern with
using an aftermarket turbo is the oil return. The stock TG uses gravity,
but I'd expect an aftermarket installation to be mounted a little low for this,
requiring a scavenge pump...... yet more weight & complexity
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.
