For builders looking to extract every ounce of power from the Nissan VR38DETT, the Ferrea Competition Plus +1mm Exhaust Valve set is the ultimate choice. These oversized valves are designed to increase the effective port area, allowing for significantly improved exhaust flow. This is critical for high-boost applications where gas velocity and volume are the limiting factors in power production.
Constructed from Ferrea’s proprietary Competition Plus alloy, these valves offer an exceptional strength-to-weight ratio. They are specifically heat-treated to resist the fatigue and thermal deformation that occur in high-output turbo engines. By choosing the +1mm oversize, you are optimizing the cylinder head for maximum volumetric efficiency, which is essential for supporting larger turbochargers and aggressive cam profiles. These valves are the gold standard for professional engine builders who demand reliability without sacrificing performance. Whether you are building a street monster or a dedicated drag car, these valves provide the stability needed to push your VR38DETT to the next level. Upgrade your engine's potential with high-quality components from GGCRACING.
