Working with Subaru’s trademark horizontally opposed engine architecture, the engine doesn’t demand a power-sapping stability shaft and, for the first time in a Subaru, the crankcase and heads are created from light-weight aluminium. Displacement is actually a shade underneath 2-litres thanks to the EJ20’s massively oversquare 92mm bore and 75mm stroke Proportions.
