    Description

    PRECISE OIL PRESSURE CONTROL. The Turbosmart OPR T40 Oil Pressure Regulator; 40 PSI is engineered to stabilize oil pressure feeding your turbocharger, preventing excess pressure that can cause premature wear or turbo smoking. By maintaining a consistent 40 psi oil pressure, it safeguards the turbocharger’s internal components while preserving oil flow without restriction. This regulator is essential for modern high-performance setups where factory turbo oil pressure profiles differ from engine output.

    CONSTRUCTION AND APPEARANCE. Manufactured from high-quality billet aluminum, this regulator offers robust durability and corrosion resistance. It features a precision-machined finish with a blue anodized coating that protects against wear and enhances the component’s aesthetics. The included mounting bracket and circlip provide secure installation, while the 1/8 NPT port accommodates an oil pressure gauge or sensor.

    INSTALLATION. Installation is straightforward and requires no drilling, making it accessible for experienced enthusiasts and professionals alike. Proper plumbing of the oil return line is essential to ensure the regulator functions optimally and maintains precise pressure control.

    APPLICATION. This oil pressure regulator is designed to fit most modern turbochargers, particularly ball-bearing types commonly found in performance engines. It is a universal solution, but some adaptation to oil feed and return plumbing may be required to achieve optimal results.
