Older Subaru engines have a unusual naming convention. Current subaru engines such as the EJ22 and EG33 are 2.2 and 3.3L engines, but the EA81 and EA82 engines from the early eighties are hardly 8.1 and 8.2L engines so here is a quick rundown on all subaru engines I know of including capacity, induction and power. Take special notice of the last 3 engines which are quite extraordinary. Subaru along with Italian company Motor Moderni (sp?) attempted the world F1 championships unsuccessfully in 1989 with its 412kW flat 12 engine. Japan loves small capacity engines in small cars which can be seen in the 1/2 litre 2 cylinder supercharged engine legally limited to 41kW
