subaru ej255

The Subaru EJ engine is a series of four-stroke automotive engines manufactured by Subaru. Introduced in 1989, they were intended to succeed the previous Subaru EA engine. The EJ series was the mainstay of Subaru's engine line, with all engines of this series being 16-valve horizontal flat-fours, with configurations available for single, or double-overhead camshaft arrangements. Naturally aspirated and turbocharged versions are available, ranging from 94 to 341 hp. These engines are commonly used in light aircraft, kit cars and engine swaps into air-cooled Volkswagens, and are also popular as a swap into Volkswagen T3/Vanagons powered by the Volkswagen Wasserboxer engine. Primary engineering on the EJ series was done by Masayuki Kodama, Takemasa Yamada and Shuji Sawafuji of Fuji Heavy Industries, Subaru's parent company....
