Do u know if the ones u saw were 2.0L boxer FA20 engine blocks ? Subaru does have the EJ20 and EJ25, the former being the bigger blocks.
Although the EJ20 blocks being close decks, and are able to pump out more power, when further tweaked, and the FA20 being a direct descent of that fabulous flat four.
Gosh ! I need to keep up to date with the new car releases !
