GSC Standard Exhaust Valve Set – Toyota 3SGTE (29mm) – GSC2071-8
High-Performance Stainless Exhaust Valves for Turbocharged 3SGTE Engines
The GSC Power-Division Standard Exhaust Valve Set is designed for Toyota 3SGTE platforms, offering a 29mm head diameter and precision-machined features to support high-RPM, high-boost applications. Crafted from modified 23-8N stainless steel, these valves deliver excellent heat resistance and long-term durability.
Engineered for Flow, Strength, and Reliability
Developed using advanced 3D modeling and simulation tools, GSC’s valve head design maximizes airflow while minimizing distortion. Each prototype is flow-tested in real-world engine configurations to ensure optimal sealing and consistent performance under extreme conditions.
Valve Features
- Swirl-polished heads improve airflow and combustion efficiency
- Back-cut profile reduces valve weight for better high-RPM response
- Micro-polished stems reduce oil retention and drag for smoother operation
- Modified 23-8N stainless steel for high heat capacity 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 for performance builds)
