Description

Boundary Oil pump Nissan VHR/HR/Rev-Up Steel Backplate with anti-cavitation porting VQ-S1-VHR-BBP

Boundary focuses on providing the highest quality lubrication systems possible for the automotive industry.

Stock oil pumps and our competitors both suffer from the stock oil pump gear design. Boundary started with a blank sheet using a design that comes straight from Boundary R&D. The new design eliminated the asymmetric tooth profile that weakens the gear in the root of the teeth. Then they added in a formulation of metal and heat treatment that has been race proven for nearly 2 decades. The result? A Boundary gear that doesn’t break, what more can you ask for?

The VQ VHR Boundary oil pump starts with the Nissan OEM housing, but is assembled with a mirror finished billet oil pump gear. This pump also comes with the option for a high flow billet backplate for those running over 7000 RPM consistently. This pump has been validated in multiple extreme horsepower naturally aspirated and turbocharged applications. It has been used in the world record holding naturally aspirated 1/4 mile car of Darren Suratt’s at 8000 RPM, and in a 8500 RPM 900WHP supercharged VHR.

All Boundary assembled billet pumps undergo the following:

  1. Pump is completely taken apart, all parts under go ultrasonic cleaning, air blast, and hand inspection.
  2. Pump is hand de-burred.
  3. Our industry leading mirror finished gear set is used
  4. Stainless Torx heads replace the stock fasteners
  5. All fasteners are torqued to spec
  6. Loctite applied to fasteners to prevent back out or loosening
  7. Anaerobic sealant applied to critical areas to boost pump up speed and reduce aeration.
  8. Assembly lubricant applied to all critical surfaces to get oil flowing fast on startup
  9. Parts are blue printed and issued with specification sheet.
