GSC Short Intake Valve – Nissan VR38DETT STD Size Single (GSC2056-01)
The GSC Power Division Short Intake Valve (PN GSC2056-01) is engineered for engines requiring precision fitment and high-flow performance. With a head diameter of <strong37.15mm, this valve is built to handle extreme boost and heat while maintaining consistent sealing. The shortened protrusion by 0.15mm makes it ideal for cylinder heads undergoing a valve job.

- 94.95mm
- 37.15mm
Using advanced 3D modeling and simulation software, GSC developed a high-flow valve head profile that’s been rigorously tested in VR38-specific applications. The result: reduced face distortion, improved sealing under high heat, and consistent performance across the valve’s lifespan.
- Promote smoother airflow across the valve surface
- Reduces mass for improved RPM response and boost handling
- 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 tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM or GSC upgraded keeper/lock (new locks recommended for performance builds)
This version features a shortened valve protrusion for heads receiving a valve job. For direct OEM replacement without machining, use GSC2050-01 or GSC2050-12.
