*Remember that this is a dual ball bearing turbo (and not a journal bearing like the Holset's commonly used on these engines). You need to keep 40-45 PSI oil feed pressure. The bearings are very sensitive to oil feed pressure. The OM60X engines can produce over 100 PSI. You'll need to use a restricted oil feed (included in our oil feed and drain kit) or a regulator.
