GSC +2mm Intake Valve Set – Nissan VR38DETT Oversize (Set of 12) – GSC2054-12
The GSC Power Division +2mm Intake Valve Set (PN GSC2054-12) is engineered for engines demanding maximum airflow and long-term durability. With a head diameter of 39.15mm—2mm larger than OEM—these valves are optimized for high-boost, high-RPM applications where sealing and strength are critical.
- 6mm
- 94.95mm
- 39.15mm
Using advanced 3D simulation and design tools, GSC developed a high-flow valve head profile that’s been rigorously tested in VR38-specific applications. The result is reduced face distortion, improved sealing under extreme heat, and consistent performance across the valve’s lifespan.
- Promote smoother airflow across the valve face
- Reduces mass for improved RPM response and boost tolerance
- Minimize oil retention and reduce drag for smoother movement
- Material: Modified 21-4n stainless steel for intake valves (heat-resistant and durable)
- Hardened or fused with stelite wafer for extended wear resistance
- Reduces valve tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM keeper/lock or GSC upgraded options (new locks recommended for performance builds)
Whether you're chasing airflow gains or long-term reliability, this is built to meet the demands of high-performance VR38DETT setups.
