GSC Intake Valve – Stainless Steel +1mm Oversize – Nissan RB26DETT Single (GSC2144-01)
The GSC Power Division +1mm Stainless Steel Intake Valve (PN GSC2144-01) is engineered for Nissan RB26DETT engines demanding increased airflow, thermal stability, and long-term durability. Featuring a larger 35.6mm head diameter and a precision-machined 5.967mm stem, this valve is optimized for high-RPM operation and aggressive cam profiles.
- Head Diameter: 35.6mm / 1.402in
- Total Length: 102.4mm / 4.031in
- Stem Diameter: 5.967mm / 0.235in
Developed using advanced 3D modeling and simulation tools, GSC’s oversized intake valve features a high-flow head profile tested specifically in RB26DETT platforms. The result: reduced face distortion, improved sealing under extreme heat, and consistent performance throughout the valve’s lifespan.
- Promote smoother airflow and better combustion efficiency
- Reduces valve mass to support higher RPM and boost levels
- Minimize oil retention and reduce drag for smoother valve movement
- Material: Modified 21-4n stainless steel for intake valves—built for high heat and long-term durability
- Hardened or fused with stelite wafer for extended wear resistance
- Reduces tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM keeper/lock systems or GSC upgraded options (new locks recommended for performance builds)
Backed by GSC Power Division’s reputation for precision, durability, and high-performance engineering.
