nice idea mate! i love the JRSC M45 on my 2.0 mondeo but i wish i'd got the M62, BUT i just didnt wanna take the risk of having it shipped over from USA to find it wouldnt fit and then have to ship it back. and i already knew the M45 would fit the zetec so i opted for that.
i had a look at a focus ST170 with the powerworks supercharger and its VERY unlikely it would fit on a zetec mondeo/contour/mystique do to it being fitted down the back of the engine and on a mondeo theres no room there and alot of other gubbins to do with the steering etc which cant be moved.
shame cos the powerworks is making over 300bhp on that focus!
incidentally the svt has different fuel rail, injectors, throttle body and fuel rail wiring loom to the zetec (to name but a few things) and these are different to the normal focus zetec parts too.
