Turbo Oil Pressure Regulator 40psi

The TURBOSMART USA Turbo Oil Pressure Regulator 40psi (part number TS-0811-0012) is a precision-engineered regulator designed to maintain consistent oil pressure within turbocharged engine systems. This OPR V2 (Oil Pressure Regulator Version 2) model delivers accurate pressure control at 40 psi, protecting critical turbo components from over-pressurization while ensuring adequate lubrication during peak boost conditions.

Built from black anodized aluminum, this regulator features 4 AN male inlet and outlet ports for secure, vibration-resistant fluid connections compatible with standard turbo oil supply and return lines. The 1/8-inch NPT gauge port allows integration of pressure monitoring equipment, enabling real-time diagnostics during tuning and engine diagnostics. Aluminum construction provides excellent thermal conductivity while maintaining corrosion resistance in high-temperature engine bay environments. At 0.29 lbs with compact dimensions (3.5 x 2.15 x 4.55 inches), this regulator installs in tight engine compartments without compromising accessibility or requiring extensive modification.

This regulator is essential for builders and tuners running forced-induction systems where consistent oil delivery prevents turbo bearing wear and extends component lifespan. Turbocharged and supercharged applications demand precision pressure regulation—excessive pressure risks seal failure and catastrophic bearing damage, while insufficient pressure compromises bearing film strength. The 40 psi setting suits most street and track-oriented turbo setups, though TURBOSMART regulators are engineered to tolerance specifications meeting OEM and aftermarket industry standards.

Whether you're assembling a custom turbo kit, upgrading factory boost pressure, or rebuilding turbo systems on performance vehicles, this regulator delivers the pressure stability required for reliable, long-term boost operation. The AN port configuration integrates seamlessly with braided stainless steel turbo oil lines and standard automotive fittings found in high-performance engine builds.
