VQ DE40 Billet Oil Pump Assembly


SKU: VQDE40-S1 Categories: , Tag:

The VQ40DE oil pump starts with the Nissan OEM housing but is assembled with our mirror-finished billet oil pump gear. The VQ40DE engines are well known for their fuel efficiency and dependability and boost between 261-275 horsepower.

This unit also comes with a preference of relief valve settings for high RPM pressure.

All assembled billet pumps undergo the following:

  • Pump is completely taken apart, and all parts undergo ultrasonic cleaning, air blast, and hand inspection.
  • Pump is hand de-burred.
  • Our industry-leading mirror finished gear set is used
  • Stainless Torx heads replace the stock fasteners
  • All fasteners are torqued to spec
  • Loctite applied to fasteners to prevent backout or loosening
  • Anaerobic sealant applied to critical areas to boost pump up speed and reduce aeration.
  • Assembly lubricant applied to all critical surfaces to get oil flowing fast on startup.
  • Parts are blueprinted and issued with a specification sheet.
