Turbosmart’s new patent pending OPR T40 is an oil pressure regulation system for your journal and ball bearing turbocharger. It helps prevent compressor or turbine stage oil leaking or smoking, and takes the guesswork out of oil restrictor sizing for more efficient and effective oil delivery. Providing an aftermarket turbocharger with the ideal oil pressure has always been a challenge. Traditionally, the turbocharger’s oil feed has relied on a restrictor system, which are difficult to set up correctly. When incorrectly sized or set up, they can be the cause of turbo seal leakage and blow-by. Turbosmart’s Turbo Oil Regulator ensures the oil pressure going to the turbocharger never exceeds the maximum pressure turbocharger manufacturers specify for oil supply, regardless of engine oil pressure. The result is an oil delivery system that is more reliable and easier to setup than a standard restrictor system.
These plumb like a fuel pressure regulator. There is an inlet port on one side, an outlet port on the other (it doesn’t matter which side) and a return port out the bottom. It has 4AN AN O-Ring ports for inlet/outlet and return. Fragola 495125-BL 4AN to 4AN O-Ring Adapter found here are the fittings you need for the inlet/outlet and return. The gauge port in the front is 1/8″ NPT and any 0-100 psi pressure gauge can be used in the port, or a sensor for data logging pressure can also be installed. You’ll need to plumb a 4AN line from the engine to the regulator, out the other side of the regulator to the turbo, out the bottom port of the regulator back to the engine (valve cover, oil pan, oil cap, etc.)
