For oil feed I am using the factory 930 fittings with the ball bearing and a 1.5 mm restrictor at the turbo for supply and a 10AN line from the turbo drain to the engine sump at the oil dain plug location. The 3LZ was rebuilt using a kit from Melett, a UK company that this shop uses regularly. They have done a good job in the past for me on Marine turbos and injectors. I have an electric scavenge pump sitting on the shelf and I could order up some more AN fittings and Plumb it in for a test but I would rather not be running a pump all the time if it wasn't completely necessary. I looked at the maps for BW S300 series and at .5 to .75 bar you never really make it onto the map. I admit I don't know how important that is but it is something to think about.
