The workshop doing my install said they've seen many cars drain the oil back into where the sump plug is. It's the lowest point in the engine, so I can't see why it wouldn't work?
Also, I had them remove the smaller 0.3bar spring from the TiAL w/gate to set the base pressure to 0.8bar. I'll then use the existing Apexi AVC-R EBC to regulate it to 1.0-1.1bar
Just popped into the shop before and had a look at the progress and all is coming together nicely. Should have the car back tomorrow night if all goes well. They're just waiting on a fitting for the oil feed and also a silicone reducer where the charge air pipe mates with the IC.
We're going away for the weekend so I'm hoping the car will be ready for the loooong cruise
I just hope there aren't any oiling/smoking issues with the GT35R. ATPTurbo said not to use an inlet restrictor in a 911 application, since the idle oil pressure is low (1.0-1.5bar) and it never exceeds 70psi under load, so fingers crossed
