Ultimate VQ Oil Pump Upgrade with Billet Back Plate

For the most demanding VQ engine builds, the Boundary Oil Pump Assembly with a Billet Back Plate is the gold standard. This high-performance unit combines the reliability of the Boundary pump assembly with the added structural rigidity of a CNC-machined billet back plate. This specific configuration is designed to eliminate housing flex and prevent oil pressure loss, making it the preferred choice for high-boost turbo or supercharged VQ35 and VQ37 engines.

Why Choose the Billet Back Plate?

  • Reinforced billet back plate prevents housing deflection
  • Maintains critical internal tolerances under high pressure
  • Essential for high-boost and high-RPM applications
  • Complete, pre-assembled unit for easy installation
  • Superior oil pressure stability compared to OEM

The addition of the billet back plate provides an extra layer of protection against the extreme stresses that can cause standard oil pump housings to fail. By minimizing housing flex, you ensure that the internal gears remain perfectly aligned, resulting in consistent oil pressure and reduced wear on your engine's internal components. If you are pushing your Nissan or Infiniti engine to the limit, this is the ultimate upgrade to protect your investment. Upgrade your oiling system with confidence and shop the full range of performance parts available at GGCRACING.
