GSC Standard Exhaust Valve – Toyota 3SGTE (29mm) – GSC2071-01

High-Flow Stainless Exhaust Valve for Turbocharged 3SGTE Engines

The GSC Power-Division Standard Exhaust Valve is precision-engineered for Toyota 3SGTE applications. Featuring a 29mm head diameter, this valve is built from modified 23-8N stainless steel to deliver superior heat resistance, airflow, and long-term reliability in high-performance setups.

Designed for Strength, Flow, and Consistency

Developed using advanced 3D modeling and simulation software, GSC’s valve head geometry is optimized for maximum flow and minimal distortion. Each prototype is flow-tested in real-world engine platforms to ensure consistent sealing and performance under extreme conditions.

Valve Features

  • Swirl-polished head improves airflow and combustion efficiency
  • Back-cut design reduces valve weight for better high-RPM stability
  • Micro-polished stem minimizes oil retention and drag for smoother motion
  • Modified 23-8N stainless steel for high heat capacity and durability
  • Stelite wafer or hardened tips for extended wear resistance
  • Optimized tip height for proper valvetrain geometry and easier valve lash setup
  • Balanced keeper groove to reduce spring shim use and enhance spring kit performance
  • Compatible with OEM or upgraded keepers/locks (reuse not recommended for performance builds)
