The FA20D engine had an aluminium alloy cylinder head with chaindriven double overhead camshafts. The four valves per cylinder two intake and two exhaust were actuated by roller rocker arms which had builtin needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms (which actuated the valves).

For the GC/GM Impreza WRX, the EJ20G engine had a watercooled, Mitsubishi TD05 turbocharger; the rotational speed of the turbine ranged from approximately 20,000 rpm to 150,000 rpm and peak boost is understood to be around 11 to 12 psi. To prevent excessive boost pressure, which could cause knocking and heavier thermal loads on the pistons, the EJ20G engine had a wastegate valve.
