Given the importance of the oil circuit in the turbo, it would not be a bad
investment to put it on its own oil circuit separate from the engine oil circuit
and perhaps with not just one electric pump, but also a redundant fail-over pump
with its own wiring and a low-pressure switch that would activate it if the
first pump fails. Another advantage beyond isolation from head gasket leaks
etc. would be that you could keep the turbo oil pump running after engine
shutoff until the turbo system has completely spun-down.
Just dreaming parts of the ultimate vehicle,
