I modded the eccentric shaft oil jets when I overhauled my '86 NA. The problem now is low oil pressure at lower engine speeds.

I have seen references to high flow (racing) oil pumps around here. I can't locate anyone who sells them. Does any one here have that information? How much does one cost?

I see the Turbo oil pump carries a different part number than the NA. Anyone know what the difference is?

Thanks for the help.
