The FA20E and FA20F engines had compression ratios of 10.
For the FA20F engine, it is understood that the ignition coil connector had a locking mechanism for greater reliability.
Furthermore, the connecting rod bearings were made from a copper-based alloy.
It is understood that the boost limit fuel cut was set around 4 psi above the boost target, though this would have to be sustained for over two seconds to cause a wastegate error code P0244 to be logged in the ECU.
Exhaust The FA20E and FA20F engines had exhaust gas recirculation EGR systems in which the piping was integrated into the intake manifold.
The hydraulic lash adjuster — located at the fulcrum of the roller rocker arm — consisted primarily of a plunger, plunger spring, check ball and check ball spring.
