GSC Power-Division Chrome Polish STD Intake & Super Alloy Exhaust Valves Set for 2JZ 2JZ-GTE Supra

When creating GSC Power Division's new valve line GSC Power Division set out to create the best performance longest lasting valves available to the aftermarket. Using advanced 3D design and simulation programs GSC Power Division have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure GSC Power Division have the highest flowing valve head available on the market today. With the materials used GSC Power Division have less valve distortion at the face than any of the tested designs. Less distortion allows or better sealing under extreme conditions and more consistent performance threw the life of the valve. GSC Power-Division's new valves are sure to become the industries standard for sport compact performance valves.

GSC Power-Division Super Alloy Exhaust Valves for the 2JZ are for those running high horsepower, high EGT set ups that need a valve that will last in 2000?F conditions. The Super Alloy Exhaust valves have chrome polished stems to create a smooth, durable finish for added life and better lubricity, especially when paired with the GSC Manganese bronze valve guides. Strength, heat resistance, and performance are engineered into every valve. Under head dish is maximized for weight savings while swirl polished and backcut heads promote better air flow without sacrificing durability.



Valve Features

  • Swirl polished heads for smoother air flow over the valve
  • Back cut to reduce valve weight for higher rpm, higher boost pressure and allow for more aggressive cam profiles without increasing valve spring seat pressures.
  • Valve stems are micropolished to allow for less oil retention on the stem which creates less drag on the stem to guide for a smoother motion.
  • Intake valves are a modified 21-4n stainless and Exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity.
  • Valve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
  • Valve tip lengths. We have taken extra time to adjust tip heights on the applications to require less tipping of the valve to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash.
  • We have also adjusted the Keeper grove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from GSC Power Division's spring and retainer kits.
  • Valves will work with an oem keeper/lock or when available GSC Power Division's upgrade keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance applications do to material grooving.
