Re: hemi swap

6.1 has a different Transmission.

You'll need A LOT more like a new Engine Wiring Harness, PCM....etc

Re: hemi swap

These swaps are doable but a giant pain in the ass. You can in theory run a 4.7 pcm on a 5.7. You will need SCT to do it. Youll need a datalogger too.

I suspect that if you havent done a swap before, to not try it on a newer mopar. There are alot of different buses that communicate with each other and the tuning is hit and miss at best. I cant help you a CMR tune because for some stupid reason Diablo only supports dodge 4.7s not jeeps at this time.

Infinitely easier. I dont know what the latest is on sourcing new HO cams from Mopar but worst case scenario you could rip some out of a junkyard for quite cheap probably.

Re: hemi swap

You want the 08+ intake...bear in mind that you will need to delete or run the 08+ EGR system too. I am not sure if anyone has successfully done the manifold swap on a WK. I was the first to successfully swap one onto a WJ.

Porting will depend on who does it...If you get someone that really knows what they are doing, with the above mods you could clear 275whp. These numbers are low because of the AWD system and trans sucking up alot of that power. the truck will be quicker than the above number would suggest.

Re: hemi swap

i was planning on airram ported heads with the ho cam and from what i understand my egr system should bolt right up all i need is the throttle body adaptor but all that is on hold i think my trans is on its way out its not the bushings because i just had one of them replaced
