I have a 97 ram 1500 4x4 5.2 litre auto,,my engine is finally in need of replacement and wanted to know what the complications of sticking a 5.9 in place of my 5.2??? Thanx Capt Joe

 

There is a bit of a difference. The 5.9L is balanced externally, the 5.2L is internal, so it'd be a few more parts than just the motor that'd need switching.

The same tranny can be used. 46REs were standard with 5.2L and 5.9L.

You will need to switch computers though. The 5.2L will not work well with the 5.9L and vice versa. Also, try to stick with the same model year to minimize electrical/wiring headaches.

More guys here will pipe up with more tips and more in-depth info, but thats about as much as I know. Keep us updated!

 

intakes will swap over if there are any big differences there.....

 

He would need a model year very near his as I believe they had EGR in 1997 and not in 1998+.

 

if the 5.9 comes as a complete bottom end, it will already have the balancer, but you will most likely need to buy an externally balanced flexplate to match

 

now that i think about it... scratch that, im not sure if it will come with a balancer... ill stop talking now

 

No EGR on my 96 , Unless it was a cali truck there was no EGR..94-95 yes.. switching from 5.2 to a 5.9 only need PCM change..

 

If it comes out of another truck, it will already be balanced.

 

I have a 97 Ram 5.2L and I don't have EGR. But thats only because we have harder emissions standards to keep up with here
