The exhaust manifold for the FA20E and FA20F engines was made from sheet metal and had hydroformed branch pipes.
The FA20E and FA20F engines are understood to have cast aluminium pistons.
The iridium-tipped spark plug caps, which provided contact to the spark plugs, were integrated with the ignition coil assembly.
Please note that this article considers the FA20E and FA20F engines as they are supplied in Australian-delivered vehicles.
Furthermore, roller lifters were used as contacts between the pump and camshafts to reduce friction; a pulsating damper was also integrated in the pump to reduce fuel pressure fluctuations.
By using EGR, combustion temperatures were reduced such that the engine was less susceptible to knock and injection timing could be advanced.
