Unleash the power of your Subaru with our top-tier EJ-S2 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.
