Intro
Interested in a complete list of Engines from Subaru ? Well, Bantum has compiled one:
Introduction into the list of Subaru Engine Specifications …
Subaru generally uses a four or five character code to identify all of their engines.
- The first letter is nearly always E - Standing for Engine, though, this only applies for Engines before the introduction of FB Engine series.
- The second letter is the engine's family.
- Next come two digits indicating the engine's displacement. (Or possible revisions in engines before 1989)
- The optional fifth character is an identifier to mark revisions. ( Ex: turbo, DOHC, Fuel Injection, etc. )
Example: EK32 or EJ206
Also for ID purposes, there is usually a part number stamped on the crankcase ( location varies for each type ) …
After each engine type there is a brief description of what it is + vehicle used in …
Note : I've used references from Wikipedia, AUSubaru + others on here to compile the list.
