I understand your problems. My installations on 911s have always used custom exhaust which located the turbo higher and draining to the chain cover was always adequate. One twin install went to a valve cover the other to the chain cover. I never use a turbo oil inlet restriction, nor would I recommend them.
I suspect your problems will be eliminated when you go to the center drain plate. There is no better dry sump pump than that location
If you wish to try one more option, the drain from the turbo can be improved by adding a small air vent. I saw a picture of this on a custom twin install on another thread. It was misunderstood as a backup drain, it was an air vent. Years ago we added air vents to turbos not having carbon seals on the compressor . This allowed operation under full pull thru intake vacuum and no seal leaks.
