04-06 Legacy GT.

The listing is for a clean and compression tested JDM EJ20x Dual AVCS motor imported from Japan with low miles.  This 04-06 Legacy GT motor came off of JDM Legacy Spec B with low miles.  The listing is for the engine only.   The engine must be used as a long block.  Please note that this model is Dual-AVCS (intake & exhaust).  The exhaust AVCS solenoid will be left unconnected.  In certain models; the flange for the downpipe is different, therefore use it as a long block application. You may need to source a flange for the downpipe or swap over your headers entirely with your uppipe & tubocharger.

The EJ20X is a notable engine in the JDM (Japanese Domestic Market) lineup, revered for its robust performance and advanced engineering. It is part of Subaru’s EJ engine family, which has earned a solid reputation among car enthusiasts, particularly in the world of rally and performance cars. The EJ20X, introduced in models like the Subaru Legacy and Outback, is a turbocharged, 2.0-liter flat-four (Boxer) engine that embodies Subaru’s commitment to performance and reliability.

One of the distinctive features of the EJ20X is its integration of an air pump, a component designed to enhance emissions control. The air pump injects fresh air into the exhaust stream, promoting more complete combustion of exhaust gases. This process reduces hydrocarbon and carbon monoxide emissions, helping the engine meet stringent emission standards. In addition to its environmental benefits, the air pump contributes to the engine’s efficiency and longevity.

Performance-wise, the EJ20X boasts a twin-scroll turbocharger, which significantly reduces turbo lag and provides a smooth and responsive power delivery. This makes the engine particularly suitable for high-performance applications, delivering a blend of power and drivability. The twin-scroll design allows for more efficient exhaust gas scavenging, leading to improved boost response and greater overall efficiency.

The EJ20X’s design reflects Subaru’s engineering prowess, combining power, efficiency, and environmental consciousness. It remains a sought-after engine in the aftermarket community for those looking to enhance their vehicles with proven JDM technology. Whether in stock form or modified, the EJ20X with its air pump system is a testament to Subaru’s innovative approach to performance and emissions management.
