EJ201 and EJ202 Subaru Engines

The EJ201 and EJ202 engines had an aluminium alloy cylinder head with cross-flow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a 'tumble swirl' motion for air as it entered the cylinder for better mixing of the air and fuel for more uniform flame travel and faster combustion.
