Brian Crower Oversized Stainless Steel Exhaust Valves for Toyota 2JZ (+1 mm) (BC3303)

When building a high-performance 2JZ engine, increasing exhaust flow is essential for maximizing turbo efficiency, reducing backpressure, and supporting higher horsepower levels. The Brian Crower Oversized Stainless Steel Exhaust Valves are engineered to provide exceptional durability, reduced valvetrain mass, and enhanced exhaust flow for demanding street and motorsport applications.

Featuring a +1 mm oversized head diameter, these valves significantly improve exhaust gas evacuation compared to standard-size valves, making them ideal for ported cylinder heads and fully developed high-horsepower engine builds. Manufactured from premium heat-resistant stainless steel, each valve utilizes a one-piece construction with a friction-welded Stellite tip for superior wear resistance and long-term reliability.

The undercut stem design reduces overall valve weight while improving exhaust flow from the combustion chamber, supporting extended RPM capability and greater engine efficiency. Fully machined and swirl-polished beneath the valve head, these valves deliver the precision and quality required for serious naturally aspirated and turbocharged 2JZ applications.

Supplied as a complete set of 12, these oversized exhaust valves are an ideal upgrade when paired with aftermarket camshafts, valve springs, and professionally ported cylinder heads.

Trusted by professional engine builders and motorsport teams worldwide, Brian Crower valves are a proven upgrade for unlocking the full potential of Toyota’s legendary JZ platform.

Carefully selected for builders who demand proven performance without compromise.
