I have two trucks both 98.5's one is a 24v auto the other is 12v nv4500 with the new style interior. my plan is to take the p pump and 5 speed from the 12 valve and put them in the 24 valve. I know I will need lines and misc. stuff but I was wondering if I will have to swap the ecm and or electronics from the 12 valve. any advice would be greatly appreciated.

 

I would suggest getting on cumminsforum.com and going to the p7100 swap section there is a whole subforum dedicated to p-pumped 24v's. I don't believe they swap the ECM out, but I could be wrong...

 

thanks I checked it out and there was a lot of info there. I really need to figure out what cam I should get cause it makes sense to get an aftermarket cam while im in there
