GSC +1mm Standard Intake Valve Set – Toyota 2JZ-GE / GTE (34.50mm) – GSC2064-12
Oversized Stainless Intake Valves for Toyota 2JZ Engines
The GSC Power-Division +1mm Intake Valve Set is engineered for Toyota 2JZ-GE and 2JZ-GTE platforms, offering a larger 34.50mm head diameter for increased airflow and performance. Built from modified 21-4N stainless steel, these valves are designed to handle high heat and aggressive cam profiles while maintaining long-term reliability.
Designed for Maximum Flow and Long-Term Durability
Using advanced 3D simulation and flow-testing, GSC developed a valve head that delivers superior velocity and reduced distortion under pressure. This results in better sealing, improved combustion efficiency, and consistent performance across the life of the valve.
Valve Features
- Swirl-polished heads enhance airflow and reduce turbulence
- Back-cut design lowers valve weight for better high-RPM stability
- Micro-polished stems reduce oil retention and drag for smoother operation
- Modified 21-4N stainless steel offers high heat resistance and durability
- Stelite wafer or hardened tips extend wear life and reduce tappet wear
- Optimized tip height ensures proper valvetrain geometry and easier valve lash setup
- Balanced keeper groove minimizes the need for spring shims and improves spring kit performance
- Compatible with OEM or upgraded keepers/locks (reuse not recommended in performance builds)
