anyone have any info on this swap, like where to get wiring harness and adapter or which tranny to run let me know

Its a dream of mine to be at a stop light and just take a moment to reflect on the awesome sounds of my turbo'd motor gushing out of the exhaust.
I haven't herd of anyone doing this swap, just thought one day of a samurai all cummins'd out. A suggestion to adding a motor like this to the samurai would be to reinforce the frame rails with lots cross bracing. I also wouldn't exactly trust the thickness of the frame rails.
What sparked the idea was being able to use the samurai to tow a 1800lb race car out of the neighborhood I live in as the roads are gravel and KILL the tires, but still be able to keep the samurai somewhat "normal".

ya it would be pretty awesome i actually have the motor on my shop floor i purchased it new and was planning on dropping it in my 69 nova but plans changed. There is a guy i know who has a 3.9 cummins in his samurai and ive actually been trying to get ahold of him for some time now. but ya never know the next picture i post very well could be my samurai with a cummins in it

I have a friend who has put a 4BT in his 79 Jeep.

It's incredibly heavy and he has yet to get it to run as he is having trouble finding suitable engine mounts.  He is also not sure if the Peugot transmission can handle it.

Although the "cool factor" would Monumental, I think you would end up with a giant pig-in-a-poke money-pit if you installed a 4BT in a Samurai.

I once saw a Sami with a 455 V-8 at a ZookiMelt.  It lasted less than a day on it's maiden voyage. At the first offcamber section of trail, it rolled.  And Rolled. 

Not pretty.

ill just keep it for a rainy day im pretty happy with the way my 1.3 runs
