Yes. I looked into getting a 5 speed manual installed into my Durango R/T. Keisler Automotive at the time made a 5 speed conversion kit from the automatic, and even that was $4K before installation (all new parts of course). For the performance benefit you'll get, even getting a second hand transmission, a bellhousing to mate it to the engine, not to mention related hardware and a computer flash you're better off buying a used manual V6 car for the same price.
