The Turbosmart OPR T40 Oil Pressure Regulator protects ball-bearing turbochargers by holding turbo oil feed pressure at a steady 40 psi - the ideal pressure for most modern ball-bearing units. It replaces guesswork oil-restrictor sizing: as engine oil pressure rises and falls through the rev range, the OPR maintains constant pressure without ever restricting flow, preventing the oil leaking and smoking that comes from over-pressurizing the turbo. Pre-set at 40 psi (non-adjustable) so there's no risk to the turbo on startup. Finished in blue.
