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 say its best to drain back into the case breather cover, that way it will drain back to the oil pump pick up tube/screen and it will scavenge back to the oil cooler (if the thermostat is open and up to temp) and then through the oil filter and back to the oil tank, that way you make sure that the boiling hot oil is cooled down and then filtered before its introduced again to the pressure side of the oil pump to be spread all over the vital engine parts. I did this to a couple of turbo projects and all is very well and never seen any high temp issues.
