even a -6 is fine: Ballbearing turbochargers require less oil & many come & require oil restrictors to limit the oil flow through the bearings, otherwise the tolerances are too close. Precision requires a very small needle-size hole through the restrictor, so a -3 to the restrictor.

BTW: my 911 turbo has a 1st gen ballbearing turbocharger: the factory -4 line supplied so much oil, the mechanical oil scavenge pump couldn't come close to keeping up. Required a serious restrictor, but have 70k on that turbocharger w/o issue & w/o water-cooling.

Im only building one example of this and its on 32V.
Restrictor (good idea I will considor);
About oil to the turbo - as now 6AN with original adaptor to turbo and Ive got the 3 qt accusump on the line. I hope the pump manage it all. I have a 12AN back to the drain.

Here's an entertaining video about rear mount turbos:
