Has anyone swapped to the hemi? I have a 2003 dodge ram 4 door and was wondering if any one has experience with a hemi swap if so how complicated is it with ecu and all that. also what year hemis will fit?
It should be a fairly simple swap involving the engine, PCM, wiring and related mounting hardware for the engine itself. Your trans will bolt right up. I woul recommend using a 2003-2005 engine unless you're looking to add MDS.
I checked into swapping my 4.7 to a hemi in my 02 quad cab and from my info gathering was told I would have have new comp. Wiring harness and was also told by mech. Tranny for a 6 cyl. And 4.7 would interchange but not with the hemi. So I would need tranny also. Again I'm not a mechanic but u should check it all out before u start spending. Good look.
from what i have heard when i wanted to do this swap u basicly have to have a totalled Hemi truck. everything out of it including the ignition and key bc the computer aparently will not allow the engine to start with another ignition or something. IDK if u find out diff tho im for sure goin back to this idea cuz i know places i can get a full hemi engine n harness for $2000
I was entertaining the idea of a hemi swap into my 05 seeing that I broke a rod and the engine shop I always deal w/ said it would work if I wanted but I don't wanna pay the extra 500~ for not returning a hemi core
