Nissan VQ DE40 Billet Oil Pump Assembly Boundary Pumps

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.

• 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 specification sheet.
