OK,
The MK2 Mondeo shares very little in common with the Jag so any ideas of using Jag parts is out of the question.
The touring cars used a very diffrent setup as the front drive shafts foul on the sump of the standard V6 and hence they used a diffrent gear and transfer box.
The MK1 Mondeo 4x4 isn't a bad starting point but the transfer box is the weakest point in the whole setup and have been known to go bang at around the 230bhp mark.
The only conversion I have ever seen in Martin's Reyland Cosworth Mondeo as there does not seem a lot of point in doing just a RWD version.
