Haven't seen or heard of it, but you'll also want pretty much everything from the ST, including the trans and the rest of the drivetrain. The cost of making sure it all fits and works properly goes up quick too.

There are a few threads in the engine & trans swap area talking about swaps into a MkIII.

TallTed started one to try & actually put info together so it could eventually be done.

Only swap to date with those was the MTX-75 into a DCT car, that helps with info. on what transmission will bolt up to the std. duratec TIVCT.

To go into an SVT would be a chore similar to the SVT into an SPI Wagon swap that was written up there recently (completed).
