Is anyone using a "lighter " oil such as 10W 30 or 15W 40 , I was told to reduce from 20W 50 'cause apparantly my oil pressure goes too high for my turbo . I am also running 9000rpm and would like to get up to 10,500rpm with 25-28 psi boost.

 

Not sure if thats good being that your in a place that somewhat stays hot year round. I know Racing Beat has a high pressure regulator for the FC, not sure how it goes for the FD.

 

Yes, I run mobil 1 5w-30. Lots of abuse for 3yrs and
going strong.
