Brian Crower Inconel Exhaust Valves for Toyota 2JZ (BC3301-INC)

When building a high-boost 2JZ engine, exhaust valves are subjected to some of the most extreme temperatures and cylinder pressures in the entire valvetrain. The Brian Crower Inconel Exhaust Valves are engineered to provide exceptional heat resistance, durability, and airflow for serious high-horsepower street and motorsport applications.

Manufactured from premium Inconel alloy, these valves are specifically intended for high-boost and high-horsepower engines where conventional stainless steel valves may be pushed beyond their limits. The undercut stem design reduces overall valve weight while significantly improving exhaust flow, supporting extended RPM capability and improved engine efficiency.

Each valve is fully machined and swirl-polished beneath the valve head to enhance gas flow and maintain consistent performance under extreme operating conditions. Supplied as a complete set of 12, these exhaust valves are the ideal upgrade when building a fully developed 2JZ-GTE or high-output 2JZ-GE turbo conversion.

Trusted by professional engine builders and motorsport teams worldwide, Brian Crower valves are a proven solution for reinforcing Toyota’s legendary JZ platform in the most demanding applications.

Carefully selected for builders who demand proven performance without compromise.
