GSC Power-Division S2 camshafts upgrade Mitsubishi Lancer Evolution 4-8 models with 4G63 DOHC engines. This matched set features 274 degree advertised duration intake and exhaust for strong power delivery from mid to high RPM. Drivers gain noticeable horsepower with proper supporting mods like valve springs and tuning.

Key Features

  • Billet 8620 Cores: Heat treated steel construction handles extreme RPM and stress for reliable long-term use
  • 274° Duration: Advertised intake/exhaust duration with 252° @ 0.050 inch drives airflow for RPM power
  • 10.90mm Lift: 0.429 inch intake/exhaust lift fills cylinders with more air for combustion gains
  • Superfinished Lobes: Polished surfaces cut friction and wear while improving break-in and durability
  • Back-Cut Lobes: 3/4 ramp design smooths transitions to reduce valvetrain noise and stress

Product Notes

  • Pair with GSC valve springs PN 7013.00 or equivalent rated 80 lbs minimum seat pressure at 1.9 inch installed height
  • Inspect piston to valve clearance and adjust timing if needed during cam swap
  • Store in dry area and avoid impacts to cores before installation

Installation Notes

  • Professional installation recommended.
  • Set cold valve lash to 0.010 inch intake and 0.010 inch exhaust
  • Works with OEM rocker arms though GSC chromoly rockers handle higher lift better
