    I know ive searched this but havnt got the definitive answer. Ive got 2 oil feed flanges with the .040 holes and i know thats too small for these journal bearings. Should I just drill it out to 3/16" to match the line or should I drill it to the .080? Dont wanna toast the new turbo.

    Run a restrictor as a last resort. Typically needing a restrictor is a sign of problems elsewhere.

    I have a stock pump rite now but with the pan dropped I was thinking of putting in my melling high volume pump. So, on a stock setup you think I should just go open? No restricion?

    I wouldnt run under a .065 on a journal bearing. Make sure the drain is at least 10an as well.
