I don't think anyone locally is running a turbo diesel. I've read messages from others that have and they've said nice things about them (better torque, economy, low rpm grunt, etc.). They've also said that the swap is hard to do.
O.K. Lars, I'll chime in ...... as far as turbo Diesels go .... I like it a lot!!!... that being said you'll have to modify your truck a LOT to get it to fit..... ( not so much with the VW diesel, but they are smaller) also have you ever seen just how small the bearings and gears are inside a sami 5 speed??? it's not going to be around long with more torque added to the mix....so just how far are you prepared to go??? ( not trying to dissuade you , just being realistic)
