For those of you 12v's that don't have the second oil drain boss in the block, where did you run your primary oil drain to? Just punch a hole in the oil pan and put a fitting in there, or is it possible to run it up to the stock oil drain at the front of the block? The turbos I'm running have an oil restriction orifice on the supply side of the bearings, so oil flow is gonna be less than that of your typical plain bearings.

 

Tate,
Here is a good thread on options for oil drains.
