The Subaru EJ20 engine is a 2.0L horizontally opposed four-cylinder gasoline engine from Subaru's EJ engine family. The EJ20 was widely used in Subaru passenger cars, performance models and SUVs, including the Impreza, WRX, Forester, Legacy and Outback.<\/p>
The EJ20 was produced in a wide range of naturally aspirated and turbocharged configurations. Power output, compression ratio, cylinder head design, fuel system and engine management vary significantly according to the specific EJ20 version, vehicle and production year.<\/p>
The EJ20 uses Subaru's horizontally opposed boxer-four layout, which provides a low center of gravity and compact engine packaging. Depending on the version, the engine can feature SOHC or DOHC cylinder heads, variable valve timing and turbocharging.<\/p>
The EJ20 has a 1,994 cc displacement with a 92.0 mm bore and 75.0 mm stroke. Naturally aspirated and turbocharged versions have substantially different power and torque outputs, so the exact specifications should be confirmed from the original engine code and vehicle application.<\/p>
The EJ20 was used in Subaru models including the Impreza, WRX, Forester, Legacy, Legacy Touring Wagon, Outback and Exiga. Different generations and markets used different EJ20 variants, including naturally aspirated and turbocharged configurations.<\/p>
Not every EJ20 engine is directly interchangeable. Cylinder heads, turbochargers, intake and exhaust systems, wiring, ECU calibration, engine mounts and ancillary components can differ between versions. Please provide the complete engine code, vehicle model, production year and VIN before ordering.<\/p>
Our used Subaru EJ20 engines are inspected by professional mechanics before shipment. We can check engine condition and perform compression or pressure testing where applicable. Detailed engine photos and available test videos can be provided before shipment.<\/p>
For turbocharged EJ20 applications, we recommend confirming the turbocharger specification and complete engine configuration before purchase to ensure compatibility with the original vehicle.<\/p>
