A lot have guys have posted about attempting this, but no one seems to know for sure. We still haven't seen anyone successfully mount one AND come back to show proof of it. Many of us are interested in seeing someone pull it off. You will be the first around here if you do it and prove it.
Some of our turbo gurus will probably chime in with some information you need to know what it will take.
Agreed, Barney had a PSD turbo on his IDI, however, it was in a compound setup and was feeding his Banks, I believe turbo mounted in a conventional manner. The PSD turbo was remote mounted under the cab, with the oiling system being run with the mechanical lift pump, and the air filter in the bed. He did see 20psi at one point in time, and then the truck broke again (hence the name "That Damn Truck"). I believe the truck was then returned to a "stock turbo" configuration and then sold.
That being said, it was not mounted at the only turbo, and the system did need some improvements. So one could be mounted and used. It will not be a "plug and play" setup, and may not fit on top like the kits do..... but anything is possible. We have a member that has a DT466 turbo remote mounted under the cab next to the transfer case.......
