I have seen it done several times.
And the svt contour did use the MTX-75 tranny, but I beleive they used different gearing.
I'm not sure how direct fit it will be, like any engine swap there is probility a fair amout of fabrication.
IMO for what it would cost you to get a svt contour motor, wire, and ecu you could up grade the zetec to have more power. If it were me I might look into a sc set up like the jrsc or the paxton sc.
