Use an oil filter... Forced performance sells them and it is manditory to get with any of their ball bearing turbos to keep it under warrenty. It lowers oil pressure and filters the oil also. When I got my turbo from them they insisted on me getting one because ball bearings dont like a lot of oil pressure, they just need a small mist/stream. I have also heard mitsu turbos are the same way, thats why the oil supply is taken from the head. This could be wrong but its what I have learned in the past.

Just a thought.
