Subaru engines

SubaruSubaru is a Japanese automobile manufacturer owned by Fuji Heavy Industries (FHI). Subaru cars are multiple winners of various auto races, and the brand itself is often the standard and benchmark for other automakers.

Subaru uses a four or five letter code to label its engines.

  • The first letter is always Latin E (from engine) (before the FB series).
  • The second letter indicates the engine family.
  • The next two indicate the displacement (or version, before 1989).
  • The fifth character is optional and indicates the version, for example: turbo, DOHC, Fuel Injection, etc.

Unlike most manufacturers who use in-line and V-shaped configurations, Subaru prefers boxer engines, the sound of which is difficult to confuse with something else. The most famous is the EJ series. Subaru’s EJ20 and EJ25 boxer engines are probably one of the most famous and popular among all encountered. In atmospheric versions, they can be found in different models, and in turbocharged versions, most often under the hood of the legendary Impreza WRX and WRX STI. Other models of Subaru engines under the designation FB20 and FB25 are also common. Of the 6-cylinder engines, on larger cars, there are EZ30 and EZ36.
