CJ-7 Diesel Swap

I want to put a cummins 5.9l "610" in a CJ7. I have the engine but need to find a jeep, looking to spend $1500-$2000 on the jeep and was wandering how much i would have to spend to complete the swap. I know i need to beef up the frame and suspension to handle the weight and I plan on getting Dana 60s for the front and back. Want a Nv5600 (Know where to get one cheap) and I would also like to know what a good transfer case would be. Thanks

good luck... You'll need a CJ8 to make the driveline length work. And thats IF you can make the 6bt fit the engine bay. a swap like this can probably be done, but not cheaply if you want it to be safe.

You may want to consider a TDK frame, instead of trying to beef up an old rusty one. The 3/16" mandrel bent rectangular tubing would be a lot stronger than the rusted thin frame on a used CJ. I would also think some firewall relocating would be required for the length of the engine and still have room for the radiator, intercooler, and fans...
