The original engine would be the easiest swap.

There is no imporant difference between Japanese market engines and North American engines. Just a few emissions changes.

Big difference between S4 and S5 as far as electronics go, but only slight changes on the engine (slightly higher compression, casting changes, a few other misc things). NA S4 and S5 engines are radically different.

And of course, all of this information can be found using the search.
