GSC P-D Subaru EJ20 JDM Euro Spec STI S2 Cams 272/272 Billet 1999-2007 Impreza STI

GSC Power-Division S2 camshaft set provides 272 degree duration intake and exhaust for JDM and Euro spec Subaru EJ20 STI engines in 1999-2007 Impreza models. Billet cores support high RPM with 11.2mm lift per lobe for strong mid-range torque and top-end power in track or street applications. Dyno results confirm gains up to 25whp over stock cams while maintaining smooth idle.

Key Features

  • 272° Duration: Intake and exhaust profiles deliver power from 5500 RPM with broad torque for daily or race use.
  • 11.2mm (0.441") Lift: Increases valve opening for better airflow and horsepower in boosted setups.
  • Billet Steel Cores: Resist flex and wear at revs over 8500 RPM and boost to 30psi.
  • 110° Lobe Centers: Balance timing to minimize valve-piston clearance issues and improve overlap.
  • Precision Ground Lobes: CNC machined profiles ensure accurate valve timing and durability.

Product Notes

  • Not compatible with USA spec EJ20 or EJ25 engines due to head and valve differences.
  • Pair with upgraded valve springs and retainers for operation above 8000 RPM.
  • Ships in protective foam-lined 12x6x4 inch box.

Installation Notes

  • Professional installation recommended.
  • Requires timing belt removal and precise cam timing with adjustable gear set.
  • Compatible with stock or aftermarket valve train on EJ207 JDM Euro heads.
