Introducing Turbosmart’s OPR V2 Turbocharger Oil Pressure Regulator, a cutting-edge solution launched in 2022 that ensures steady oil pressure for your turbocharger. This innovative regulator features a return-less design with an integrated 44 Micron Stainless Steel Mesh Oil Filter, providing robust performance and protection.

The OPR V2 is the first of its kind, utilizing Turbosmart’s proprietary flow control method to maintain optimal oil pressure regardless of engine oil variables like pressure or temperature. It guarantees a smooth oil flow to your turbocharger, safeguarding critical components such as Exhaust Drive, Back & Charge Pressures from excessive oil pressure that could lead to oil consumption and smoke.

Gone are the days of guesswork with restrictors and complex plumbing for oil pressure regulation. The OPR V2 simplifies the process with its return-less, inline installation and the convenience of a built-in 44 Micron Oil Filter. This filter, made of serviceable and replaceable Stainless Steel Mesh, adds an extra layer of defense against engine oil debris that could harm your turbocharger.

Key Features:

Innovative Patent Pending Design Durable Aluminium (6262 T6) Anodised Body & Valve Regulated Oil Pressure Compatible with Most turbochargers Integrated Stainless Steel (304) Mesh Oil Filter -4AN Inlet and Outlet for easy installation 1/8 NPT Sensor/Gauge Port for monitoring Directional Inlet Feed Logic for optimized performance Laminar Flow Output for consistent oil delivery Compatible with all Engine Oils Designed and Manufactured in Australia
