Ferrea F2131P Competition Plus Exhaust Valve Nissan RB26DETT 30.15mm Stock Size

The Ferrea F2131P Competition Plus exhaust valve is engineered as an extreme duty valve designed specifically for 6-cylinder inline 24-valve engines such as the RB26DET found in the 1992-2001 Nissan Skyline GT-R. This stock-size replacement valve is built to withstand the extreme exhaust temperatures generated by turbocharged, nitrous, and supercharged applications.

Key Specifications:

• Head Diameter: 30.15mm
• Stem Diameter: 6.9mm
• Overall Length: 101.52mm
• Tip Length: 3.5mm
• 22-degree flow radial groove configuration

Manufacturing Excellence:

• Constructed from aerospace quality alloys including EV8-Z18 for high tensile strength
• Two-step slow forging technique applied to special alloys
• Heat-treated and stress-relieved over a 48-hour period
• Avionics-quality hard chrome with specially applied hard tip
• Swirl polished head for optimal flow characteristics

These valves are designed to handle high RPM operation and high spring pressures, making them ideal for racing and extreme performance builds. The special alloy construction manages the intense heat generated in forced induction applications while maintaining the strength needed for high horsepower at elevated engine speeds.
