    Cummins swap?

    Ok so this is a long distant plan, but most of yall know i have the little ol V6 and ive been looking into doing a cummins swap. Ive seen alot of people doing 4bt swaps. I know there is enough room for the 4bt but what about fitting the bigger 6bt (12v or 24v)?

    If this happens it wont be for atleast 2 or 3 years but how awesome would it be to have a cummins in a XK?

    and what all would i need for the swap? any input would be greatly appreciated.

    I really doubt you'd be able to get 6bt in there. Don't they weigh like 1000lbs also? Everything will have to be upgraded to handle the torque. Not to mention getting all the computers to work. If you really want a diesel in your XK, the best option to get it to work well would be the OM642 CRD that was available in XHs and WKs/WHs. That would be pretty pricey unless you found a wrecked one or maybe a wrecked E class or M class. The newer ones have a bigger turbo and make 455ft-lbs stock. How much power are you looking to make? With just a tune on mine, I can make 460 ft-lbs.

    im not sure i was just looking around but i would love a fair amount of power. ive looked into a HEMI swap but too many people have that already and wanted to try something different.

    Besides, after i pay off my XK ill get another DD and make the XK my toy/project

    You could do a 6.1 SRT Hemi swap...I think there was a guy on jeepcommander.com that did one. A 3.0 CRD could definitely make 500 ft-lb with the right mods. The tranny would need to be upgraded to handle the torque though.

    Yeah i would prefer to go with a Diesel, There is not many diesel XKs in the states and it would be awesome to have one.
