GSC P-D Subaru/Scion FA20 Chrome Polish Exhaust Valve - 30mm Head (+1mm) - Set of 50

This is a set of 50 GSC Power Division exhaust valves, specifically designed for Subaru and Scion FA20 engines. These valves feature a 30mm head diameter, which is 1mm larger than stock, and a chrome polish finish. They are intended for engine builders and performance shops working on high-performance FA20 applications where improved airflow and durability are critical.

The GSC Power Division B2133-50 set includes 50 valves, providing enough for multiple engine builds or a complete set for a single, high-performance engine. The chrome polish finish on the valve face is not just for looks; it helps reduce carbon buildup and friction within the combustion chamber, contributing to more consistent performance and potentially longer valve life. The +1mm oversized head diameter is a common modification for performance builds, as it increases the valve's surface area. This allows for better gas flow into and out of the cylinder, which can lead to improved horsepower and torque, especially when paired with other engine modifications like upgraded camshafts and porting.

When rebuilding or modifying your FA20 engine, using high-quality internal components like these GSC Power Division valves is essential for reliability and performance. Ensure you consult your engine builder's specifications or the GSC Power Division technical documentation for proper installation procedures and compatibility with your specific build. This set is geared towards serious engine builds where every component is chosen for its contribution to overall performance and longevity.
