Subaru''s EJ255 engine was a turbocharged 2.5-litre horizontally-opposed (or ''boxer'') four-cylinder engine. For Australia, the EJ255 engine was introduced in the Subaru SG Forester XT in 2003, but subsequently offered in the GD/GG Impreza WRX and BL Liberty GT (see table below). Developed in conjunction with the more powerful EJ257 engine, key features for the EJ255 engine included its:
