Hx35 oil feed restrictor
When I was doing my 606 conversion including a VNT Garrett turbo, all the material and advice I could dig up at the time indicated the largest drain I could fit. So far, so good. If you have a hydraulic hose shop nearby, don't hesitate to use them. Good drainage= less oil into the boost air. You'll still get some but the goal is to minimize it via good drainage and turbo bearings.
