GSC +1mm Intake Valve – Nissan TB48DE Single (GSC2084-01)
The GSC Power Division +1mm Intake Valve (PN GSC2084-01) is designed for Nissan TB48DE engines requiring increased airflow, thermal stability, and long-term reliability. Featuring a larger 39.50mm head diameter and a durable 7mm stem, this valve is built to handle high boost, elevated RPMs, and aggressive cam profiles.
- Stem Diameter: 7mm
- Overall Length: 100.20mm
- Head Diameter: 39.50mm (+1mm oversize)
Developed using advanced 3D design and simulation software, GSC’s intake valve features a high-flow head profile tested specifically in TB48DE applications. The result: reduced face distortion, improved sealing under extreme heat, and consistent performance throughout the valve’s service life.
- Enhance intake flow for smoother combustion
- Reduces valve weight to support higher RPMs and boost levels
- Minimize oil retention and reduce friction for smoother valve movement
- Material: Modified 21-4n stainless steel for intake valves—built for heat resistance and 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 maximize spring/retainer performance
- Compatibility: Fits OEM keepers/locks or GSC upgraded options (new locks recommended for performance builds)
