F series motors are pretty stout to begin with, but I wouldnt call them the KING of 4 cylinders. The F20 motors came from the F22A/B motors in Preludes and Accords from the 90s to 1998 I beleive, iron sleeved with like 8.8: compression ( F22A/B motors) was ideal for boost.
The F20c motors took some of the F22 attributes ( including the 0 00 0 exhaust pattern in early heads) and they included a dual cam head and a better intake setup.
