Its not reconmended as the svts have a slightly higher compression ratio...so for the performance you do get, its not worht the price of the ECU.(read the link, theres other problems with it)..get a chip after you have done ALL the bolt on mods you can....I reconmend getting it form Arizona Dyno Chip (Street Flight) after you have succeded in getting all your parts.
also, If you have a 1995 contour, the SVT ECU will not work, because a 1995 ia OBDI as a 1996 and up is OBDII.
If you need more info, please use the search feature in the Duratec Performance section, I typed in ECU and turend up abpout 10 diffrent topics on it, from just recently.
