Nissan SR20DET S14/S15 – Billet Oil Pump Gear

BILLET 4340 oil pump gears for the Nissan SR20DET S14 and S15 engine. These gears are direct replacements for the OEM Oil Pump and measure approximately Ø77mm OD and 10mm thick (outer gear).

This set replaces the standard gears which are prone to failure even on light modification. The factory gears are sintered (powdered metal, compressed under extreme pressure and heat) and were never designed for high horsepower or high RPM applications.

Precision machined from 4340 billet steel, featuring an N1 spec ‘wave’ profile for higher flow, HSE gears have been repeatedly proven under extremely harsh conditions. All HSE oil pump gears now go through isotropic polishing for stress-free, smooth running.
