Unleash the power of your Subaru with our top-tier EJ-S2-M billet pump: Engineered with a robust 12MM gearset for enhanced performance and longevity.

• Every billet pump we build goes through an extensive quality process to ensure it meets the highest standards:
• We commence with a meticulous disassembly, followed by ultrasonic cleaning, air blasting, and a thorough hand inspection.
• Hand deburring eliminates any potential imperfections for seamless operation.

Our industry-leading mirror-finished gear set is integrated for superior efficiency.
Experience increased pump reliability with our dual-stage heat-treated Revolution Series shark tooth gerotor.
As a testament to our commitment to quality, we replace the standard fasteners with Stainless Torx heads, and apply Loctite to them, providing additional security against loosening or backing out.

Boost your pump's efficiency with our specially applied anaerobic sealant, designed to increase pressure and minimize aeration. Assembly lubricant on all critical surfaces ensures oil flows swiftly from the get-go, protecting your engine components during startup.

Each of our parts is meticulously blueprinted and comes with a specification sheet, offering you complete transparency and trust in our process.
Want more pressure? We offer shims: one shim adds +10 PSI and two adds +20 PSI.
