The CSVT's duratec is (relativly) the same as in a non SVT duratec so the 2 would obviously be interchangable. as for sticking that into the zetec...your going to be mising a lot of tubing. you probable could make something up, but i think youd get better resualts if you just built your own custom intake. take a look at some of the stickies in zetec performance.
