Got a reply from extreme psi. Mitsubishi's warranty is only 90 days after date of purchase on any defects/problems with turbo. Obviously I'm way out of the time period even though I got the car running close to 3 mouths after purchase.

Barry, high oil pressure on journal bearing turbos is actually a bad thing.
You can also have a problem with an ol drain that is too small.
That's why Mitsubishi built a restrictor into the feed line as std.

I've seen this come up a few times with rebuilds. New/good turbo going on after a rebuild and either blowing white smoke, or in the case of a GT30 - seized. I've never rebuilt a motor but everything that I've heard/read/experienced in 3rd party is NEVER use a good/new turbo on a freshly rebuilt motor. Either run no turbo or a piece of shit turbo that you don't give a crap about because the swarf/dags/etc from the rebuild (no matter how much the rebuilder reassures you) will end up in the turbo oil lines and either block the feed or score the bearings.
Just because someone, even the rebuilder, tells you that it's OK doesn't mean jack nor does it leave them accountable. Mate had the GT30 die on him and he was still the one left with the $1100 rebuild bill with no leg to stand on other than the "word" of the rebuilders.

I took the turbo apart and the oil seal on the exhaust turbine side which clips in was missing. Everything else seems to be fine and checked. Bought a rebuild kit - spins good now. In the process of gradually putting the car together.
