Has anybody ever converted a non-turbo [DSM] to a turbo [DSM]?

Most people who research this topic come to the conclusion that it is cheaper to sell the NT and purchase a turbocharged DSM, rather than attempt to convert the NT to turbocharged form.   It has been pointed out that the difference between a turbo FWD and a non-turbo FWD 1G DSM was roughly $1000 in 1998 - suffice it to say that the conversion will be significantly more than that, regardless of the method chosen.

With AWD DSMs running in the $1500 - $8,000 area, why would you want to do this? Do yourself a favor and just buy an existing AWD.
