Crafted to meet the demands of enthusiasts seeking increased power, durability, and reliability, these valves are ideal for high boost and high RPM applications. Whether you're building a race-ready setup or enhancing your daily driver, these valves help support your performance goals by improving airflow and combustion efficiency.

Constructed with precision and attention to detail, these stainless steel valves are engineered to withstand the extreme conditions of high-performance tuning. They are an excellent choice for those looking to push their RB26DETT engine beyond stock limits while maintaining long-term reliability and consistent performance.

Key Features

Brian Crower’s +1mm stainless steel exhaust valves incorporate advanced design features to maximize engine performance and durability. These valves are made from premium-grade, heat-resistant stainless steel material, ensuring they can handle elevated combustion temperatures and high boost pressures without warping or failure.

• One-piece construction with a friction-welded Stellite tip for enhanced durability and wear resistance, especially in aggressive tuning scenarios.
• Undercut stem design above the head reduces overall weight, which helps extend RPM potential and reduces valve float at high engine speeds.
• Optimized airflow geometry to improve exhaust gas flow out of the combustion chamber, supporting increased horsepower and torque.
• Precision manufacturing and quality control ensure a perfect fit and reliable operation in high-performance applications.
• Designed specifically for the RB26DETT engine, ensuring compatibility and ease of installation.

Construction & Design

These valves feature a robust one-piece stainless steel construction, providing excellent strength and heat resistance necessary for high-performance engines. The friction-welded Stellite tip offers superior wear resistance, especially in aggressive tuning environments where valve longevity is critical. The undercut stem design not only reduces weight but also enhances airflow, contributing to improved engine breathing and efficiency. Every valve is meticulously manufactured to strict tolerances, ensuring a precise fit within the valve seats and compatibility with stock or aftermarket valve springs.

Installation & Fitment

Installing these valves requires basic engine disassembly and valve spring removal. They are designed as direct replacements for the stock exhaust valves in the RB26DETT engine, making installation straightforward for experienced mechanics or enthusiasts familiar with engine rebuilds. No special modifications are necessary, and no tuning is required solely for the installation of these valves. However, it is recommended to inspect and upgrade related components such as valve springs and retainers to maximize performance and reliability.

• Direct fit for 1999–2002 Nissan Skyline GT-R RB26DETT engines.
• Installation may require professional engine assembly experience.
• Ensure proper valve seat sealing and clearance during installation.

What's Included

• Set of (x) stainless steel exhaust valves with +1mm diameter increase
• Complete with friction-welded Stellite tips

Ideal For

Performance enthusiasts building high-horsepower RB26DETT engines, racers seeking durability at elevated RPMs, or anyone upgrading their Skyline GT-R for spirited driving or track use. These valves are perfect for high boost applications and engines tuned for maximum airflow and efficiency.
