I have an opportunity to buy a stockSVT Supercharger out of an 04 Mustang Cobra that had a 4.6. Is there anyway that this would fit in my 4.0?????

 

Its been tried before, there is no adapter out for it yet...and you have to cut into the firewall to get it to fit. You will also need a cowl hood to clear it.

 

not worth the effort. For the money it would cost to fab up an adapter plate, fit the thing on and do everything else you could probably go turbo. If i was gonna go through all the trouble of fabbing up a blower it'd be a twin-screw.
