GT1R OPR Kit V2
By restricting the oil pressure feeding both turbochargers the GT1R Oil Pressure Regulator kit greatly aids in reducing smoking caused by excess pressure getting past the internal seals on the turbochargers. This kit is easily adapted to a variety of turbo kits on the market.
Details
This kit picks up oil from the factory oil distribution block, caps the other turbo oil feed no longer being used on the block, feeds both turbos, and returns excess oil into the factory oil fill neck. All parts are included.
Frequently Asked Questions About the GT1R OPR Kit V2
What is the function of the GT1R OPR Kit?
The OPR (Oil Pressure Regulator) Kit is designed to limit and regulate the oil pressure feeding the turbochargers. This prevents high oil pressure from forcing its way past the internal turbo seals.
Why do turbos smoke without an OPR?
Many high-performance turbos (especially ball-bearing units) require less oil pressure than the VR38 engine produces at high RPM. Excess pressure can overwhelm the seals, causing oil to leak into the exhaust and create smoke.
Is this kit compatible with stock turbos?
While primarily designed for aftermarket turbo kits that are prone to seal leakage, it can be adapted to a variety of setups. It ensures both turbos receive consistent, safe oil pressure.
Does this kit work for both turbochargers?
Yes. The GT1R OPR Kit V2 is designed to regulate the oil supply feeding both the left and right bank turbochargers simultaneously.
Is the installation difficult?
The kit is designed for straightforward adaptation to existing oil lines. However, as it involves modifying the turbo oil feed system, professional installation is recommended to ensure no oil starvation occurs.
