Description

Upgrade your Subaru FA20 engine with the JE Pistons FA20E/FA20F series piston set, designed for high-performance applications and engineered for durability. Crafted from high tensile strength 2618 aluminum and forged in the USA, these pistons are built to withstand the demands of racing and spirited driving. The set includes four pistons, each with a 86.25 mm bore, +0.25 size, and a compression ratio of 10.6:1, optimized for enhanced power output and efficiency. These pistons are specifically tailored for Subaru’s FA20 series, ensuring precise fitment and reliable performance in your engine rebuild or upgrade. The piston design features JE’s proprietary Forged Side Relief (FSR) forging, which minimizes friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. This results in improved throttle response and lower operating temperatures, contributing to overall engine longevity. Additionally, the pistons incorporate an accumulator groove that helps reduce pressure from combustion gases, decreasing ring flutter and enhancing ring seal for consistent power delivery. The skirt coating reduces friction and wear on the piston skirts and cylinder walls, while also lowering operational noise, providing a smoother running engine. Each piston set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring complete assembly readiness. Designed with precision for high-demand performance, these pistons balance durability with optimized performance, making them ideal for racing, tuning, or high-performance daily driving. As a product made entirely in the USA, JE Pistons guarantees quality and consistency. Note that these pistons are not CARB-approved, and acknowledgment of this is required during installation, ensuring compliance with local regulations. Suitable for various high-performance applications, the JE Pistons Subaru FA20 series set is an excellent choice to unlock the full potential of your engine while maintaining reliability and efficiency.
