    FA20E and FA20F Subaru Engines

    The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chain driven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had built in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.
