SUBARU EJ20 PISTON -11cc 92MM BORE 2.953 STRK 5.137 ROD 8.5

Description

Enhance your Subaru EJ20 engine’s efficiency and reliability with this precision-engineered piston designed to optimize combustion and mechanical performance. By reducing the combustion chamber volume by 11 cc, it improves compression ratios, resulting in increased power delivery and fuel efficiency.

This piston features a 92 mm bore diameter, matching the cylinder specifications for a perfect fit that minimizes blow-by and maintains optimal sealing under high-pressure conditions. The 2.953-inch (75 mm) stroke and 5.137-inch (130.5 mm) rod length are calibrated to sustain engine balance and reduce mechanical stress during operation, promoting longevity and smoother power transitions.

Manufactured by JE Pistons, known for precision and durability, this component weighs 2.3130 kilograms, balancing strength with lightweight design to reduce reciprocating mass and improve throttle response. Its dimensions—12.70 cm in length and width, and 22.90 cm in height—ensure compatibility with the EJ20 engine block while maintaining strict tolerances for optimal fitment.

Constructed from high-grade materials, this piston withstands the thermal and mechanical demands of high-performance engines. The -11 cc design modification fine-tunes combustion chamber dynamics, essential for tuning enthusiasts seeking enhanced power without compromising reliability.

Installation of this piston supports sustained high RPMs and aggressive driving, making it an ideal upgrade for performance builds or engine rebuilds targeting improved output and efficiency. Its specific sizing and engineered specifications reduce the need for additional machining or modifications, streamlining installation.

Invest in a piston that delivers measurable performance gains through precise engineering and material quality. The SUBARU EJ20 piston by JE Pistons embodies the balance of power, durability, and fitment accuracy necessary for serious engine enhancement projects.
