Modifying 12A oil press. regulator
 

Is there a way to modify the stock oil pressure regulator to get 80-90 PSI?

I thought I had seen a tech write up on this, but now I can't find it.

see the 1st gen for sale section. Maybe he can tell you how its done.

You need one of the older pressure regulators which bolt together. Pull it apart and shim the spring a good 1/8 inch. Presto, 90 PSI.
