Oil Pump w/Billet Gear Subaru ALL EJ Engines

The Oil Pump w/Billet Gear Subaru ALL EJ Engines from Boundary Racing Pump is designed for builders and enthusiasts who are pushing their EJ-platform motors beyond factory limits. This aftermarket replacement is ideal for high-boost turbo builds, extended track duty, or sustained high-RPM competition, where maintaining adequate oil pressure and flow is critical.

Constructed from precision-machined billet material, this pump features a hardened gear set that can handle increased displacement and elevated RPM thresholds without wear or cavitation issues. The billet construction eliminates casting porosity and material brittleness found in OEM pumps, resulting in superior durability and tighter tolerances. The optimized gear profile ensures maximum flow rates across the entire operating range, maintaining oil pressure stability.

This pump is compatible with Subaru EJ20, EJ22, and EJ25 engines, making it a great choice for various Impreza, Legacy, Outback, and Forester platforms. Installation follows factory bolt-on procedures, requiring no modifications to the block or pickup tube, making it accessible for serious builders and motorsports competitors alike.
