the old jackson racing s/c for the zetec focus worked and I know of a couple of 2L zetec focus owners that use the rotrex jackson racing on theirs, they run without a/c though with the s/c in it's place. i guess the only question is if you can live without a/c. one of my friends (roger) has the rotrex on his 2l zetec focus and puts 252/213 hp/tq at the wheels but has other mods as well (ie focus sport cams, the old cosworth enclosed racing intake manifold w/ custom intake, injectors (not sure what kind,) full exhaust, msd coil pack and custom 93 octane tune.) He swears up and down all these mods would work on our zetecs except for the exhaust but did mention the zetec in his car was a contour zetec block and head with the rest of the internals bought aftermarket or stock from his original engine. some parts he's got on the car have been discontinued.
