Oiling issues on DSM turbos...
Given the size of the stock oil feed line for DSM turbos (14b's, and T25's) it seems like maybe the oil pressure (on DSM's) is dramatically lower than when we plumb in an oil feed line on our Hondas from the oil pressure sensor. Not to throw names around, but Kenny Tran said that 2mm is about ideal for the oil feed line diameter. However, the DSM feed lines are substantially larger. When I connected a 1/4" oil feed line to the remaining section of stock tubing on my T25 (on a D16Y8), the turbo smoked somewhat under decelleration and low rpm's (odd...), but I know the bearings are in great shape. I tightened down a section of the line in an attempt to reduce the smoke and it did reduce the smoke, but not completely. Now I'm wondering whether to shrink the opening all the way to the 2mm diameter hole that Kenny suggested. My main concern is that this is waayy smaller than the stock feed line diameter and I don't want to burn the bearings. Thoughts? Opinions?
