I am using a ball bearing turbo, there is pretty much no oil pressure on the exit side of the turbos bearing (apparently) and gravity is not enough even with a downward running line.

Plan for now is to use a catch can under the turbo, to a electric scavenger pump where the 930 scavenger pump would typically be, then feed it back to the oil tank via a 930 OEM line. I'll eventually swap this to a mechanical 930 pump run from the cam.

I'm not sure how the 930 line connects to the oil tank and what is required there. I want to stop draining to the sump plug and I don't love the idea of draining the hot oil, although not huge volumes of it into the cam covers.
I have read several times that the oil film in the intake of 930s is common place because of the design of the stock turbos
