turbo oil drain

this is my first go at a turbo so still learning. the vortech oil line was not much smaller but connected to a restrictor nozzle that was directed at the gears.
Mad Dart suggested a .080" restrictor. i'm thinking Holley jets.

Type "Turbo Oil Restrictor " in an ebay search. It will give you some ideas on how to home brew a good one.

I have used drilled out Allen set screws in an fittings before to restrict fuel. It is cheap and works very well.
