Threads in oil filter housing

[asshanson]

I think I have the external cooler, I have the 90 waterpipe and soon the t-stat housing as well with only one water line for the turbo. The 1/8" npt threads were on the bottom of the filter housing, and the larger 3/8" or whatever threads are on the back side of the housing, but that one is plugged.

Yea once my car warmed up I have like 7 or 8 psi at idle, and 40-50 psi at 2500rpm. Using 10w-30 I think right now, no balance shafts.
