The rwd 2.3 block is a bit different for the bell housing I think. Fusion/focus/escape/mazda3/mazda6 all share the same block basically. The usual only difference is the cams, timing sensors and the knock sensor, and I think a balance shaft inside the bottom end, I don't know if the focus got one. I put a fusion 2,3 into a Mazda 3 swapping cams and sensors, beware to buy the correct spark plugs for the car the motor came from, they are different lengths. I know this the hard way after a miss fire code and conditional etest passes that cost a lot.
