Did you put a restrictor in the turbo oil supply line?The turbo can't handle full oil pressure. Nice job, so the weird angled oil filter mount worked out better than a normal oil filter mount that points straight downward?
My understanding was that the bearing type used in the turbo determined whether or not it needed a restrictor. The journal type used in all VWs will take full pressure (and need it) while the ball bearing types require a restrictor both because they don't need the oil pressure to keep the parts from self-destructing and because they will pass enough oil to cause pressure loss in the rest of the system.Andrew
