The newer engine while of the same series as the 05 has more power. You may run into engine control issues. I would talk to a diesel specialist to see if your 05 ECU will work with the newer engine. If you have a 2007.5 engine there were changes to the EGR and engine displacement. https://cumminsengines.com/pickup-truck-cummins-ram-history
