Product Description

The Boundary 2JZ-OPG-DR billet oil pump gear set is engineered to resolve theweaknesses found in factory 2JZ oil pump gears, especially in engines operatingat high boost or extended high RPM. Its dual-rotor gerotor design significantlyimproves oil volume and pressure stability across the entire rev range.

Manufactured from chromoly billet and heat-treated for maximum durability,these gears are designed to survive extreme loads common in racing, high-power,and turbocharged engine builds. Precision-ground profiles and tight tolerancesensure smooth, efficient oil delivery, making this an essential upgrade for anyhigh-performance or track-focused 2JZ project.
