Specifications
The Subaru EJ25 engine is a 2.5-liter (2,457 cc) horizontally opposed four-cylinder boxer engine produced from 1994 to 2021, available in both naturally aspirated and turbocharged configurations to power popular Subaru models such as the Impreza, Legacy, Forester, and WRX/STI. Built around an aluminum block with a 99.5 mm bore and 79 mm stroke, the EJ25 typically features a 4-valve-per-cylinder layout and a belt-driven camshaft system, with SOHC or DOHC designs depending on the variant.
Naturally aspirated versions like the EJ251 and EJ253 are tuned for reliability, fuel efficiency, and everyday drivability, while turbocharged DOHC models such as the EJ255 and EJ257 are performance-oriented, delivering up to 300+ horsepower and around 300 lb-ft of torque in STI applications, often enhanced with forged pistons and Subaru’s Active Valve Control System (AVCS). Renowned for its low center of gravity, balanced handling characteristics, and distinctive boxer exhaust rumble, the EJ25 remains a highly tunable engine platform, though it demands diligent maintenance particularly of the timing belt and cooling system due to its interference engine design.
Engine Variants
EJ253 (2004–2012)
The Subaru EJ253 is a naturally aspirated 2.5-liter SOHC boxer engine designed for efficiency, reliability, and reduced emissions. Used in models like the Impreza, Legacy, and Forester, later versions introduced Active Valve Control System (AVCS) on the intake cams to improve low-end torque and fuel economy, making it a dependable daily-driver engine.
EJ254 (1998–2004)
The EJ254 is a naturally aspirated DOHC 2.5-liter engine that served as a transitional performance-oriented option in select markets. Featuring AVCS and higher-revving characteristics than SOHC variants, it offered improved airflow and responsiveness, though it was less common than other EJ25 configurations.
EJ255 (2005–2014)
The turbocharged EJ255 is a DOHC performance engine found in models such as the WRX, Forester XT, and Legacy GT. Equipped with AVCS and a factory turbocharger, it delivers strong mid-range torque and excellent tuning potential, making it a popular choice for enthusiasts seeking power with daily usability.
EJ257 (2004–2021)
The EJ257 is Subaru’s flagship EJ25 engine, developed specifically for the WRX STI. Featuring a semi-closed deck block, stronger internals, and a turbocharged DOHC layout, it is capable of producing 300+ horsepower from the factory and significantly more with modifications, earning a reputation as one of Subaru’s most performance-focused engines.
