Proper balancing is an essential part to all engines, not just I4's, and
the smooth running of an engine starts with the proper balance the rotating
assembly. This is the reason the Zetec can run more smoothly than the
subies do despite the common misperception that being a boxer automatically
provides a smoother running engine. If you get any rotating assembly to
less than 2g/in per plane you're going to be doing very well. We are
currently running a study comparing the balance of the zetec, subie 2.2,
2.5, and the aba VW 2.0l assemblies and should have some hard data  in June
or July, so stay tuned... and balanced :)
