If you're looking to build a high-performance FA20 engine, JE Pistons offers a well-built forged piston kit designed specifically for this application. This set includes four pistons with a 10.5:1 compression ratio, aiming for optimized power and durability in demanding situations. JE Pistons has been making forged pistons for over 75 years, and this kit is engineered and manufactured entirely in the USA using 2618 aluminum, known for its high tensile strength.

This kit features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for weight savings. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Additionally, a skirt coating can be included to further reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise. These pistons are designed to fit your specific engine, ensuring optimized performance and durability.

This set comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation. It's important to note that this kit is not CARB approved and cannot be shipped to California. For installation, always refer to the manufacturer's instructions to ensure proper fitment and performance.
