GSC Standard Intake Valve – Toyota 3SGTE (33.50mm) – GSC2072-01
High-Flow Stainless Intake Valve for Turbocharged 3SGTE Engines
The GSC Power-Division Standard Intake Valve is precision-crafted for Toyota 3SGTE applications. With a 33.50mm head diameter and a stem length of 100.50mm, this valve is built from modified 21-4N stainless steel to deliver exceptional airflow, heat resistance, and long-term reliability in high-performance environments.
Designed for Flow, Strength, 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 profile reduces valve weight for better high-RPM response
- Micro-polished stem minimizes oil retention and drag for smoother motion
- Modified 21-4N 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)
