I think its still cheaper to get a taurus motor. that being said, I have an escape 3.0. You can use the escape timing cover, escape pan (which is the 'improved' one). there is one ear in the back to trim for the SVT oil cooler, and the obvious alternator ones. Im also not sure if the taurus engine mount works, but know that the escape one does. The mariner should be the same 3.0, Rob(?) the turbo 3 liter in the classifieds has a tribute motor which is the mazda variant of the escape.
And ill tell ya now, if you use the escape timing cover, you dont have to swap the pulse wheel around :blackeye::blackeye::blackeye::blackeye::blackeye::blackeye::blackeye::blackeye::blackeye:
