2009-2024 Nissan GT-R

Take your Nissan GT‑R’s performance engine to the next level with the GSC Power Division Super Alloy 1.0mm Oversize Exhaust Valve. Designed specifically for the VR38DETT 3.8L V6 engine, this high‑performance valve is built to handle extreme temperatures, high RPMs, and elevated boost pressures — conditions that often push stock valves beyond their limits.

When heads are machined or valve seats are reworked during engine rebuilds or performance upgrades, these oversize exhaust valves restore proper sealing surface area and ensure reliable exhaust flow. The use of premium super alloy materials provides exceptional heat resistance and durability, making this valve ideal for high‑output, forced‑induction applications.

Why Upgrade to Oversize Super Alloy Exhaust Valves

Stock exhaust valves are engineered for standard power levels and may not hold up when headwork or performance modifications are performed. Oversize valves are necessary when:

• Cylinder head machining increases valve seat width after valve jobs

• High boost and high RPM usage increases thermal and mechanical load

• Exhaust flow and reliability are critical for performance gains

This 1.0mm oversize super alloy exhaust valve ensures proper fitment, sealing, and strength in rebuilt or high‑output engines, providing confidence in track or competition environments.
