Cummins 6.7 in obs ford

[Daniel McCurdy]

So has anyone swapped a 6.7 cummins into a obs ford. What engine mounts did you use. Were you able to use a mechanical fan. Trying to decide weather to swap in a 12v cummins, dt360, or a p7100 swapped 6.7. I want to be able to use a mechanical fan but iv never seen anybody be able to with a dt360. I know one will fit with a 12v cummins so should the 6.7 also have enough room for a mechanical fan.

Hello anybody

This sites gotten pretty slow lately, a quick Google search says a 5.9 is 40" in length and a 6.7 is 41.7" in length. Pretty much anything is possible, if there's a will theres a way, local shop (fat fender garage) just squeezed a raptor engine into an old ranger... as far as mounts you can almost guarantee you're going to be using a custom mount based off whatever engine you go with. If you have deep pockets, I vote dt360 and stock up on whatever parts you can find.. if the pockets are not so deep, you want better fuel mileage, and plenty of replacement parts you can't go wrong with the five-nine.

There's several websites that sell everything you would need for a Cummins swap.

The more I look the more it seems like the 12v swap is the way to go just for simplicity and ease of parts. Can the 12v make torque like the new powerstroke 1050 at only 1800 rpm

I'm still a newb to diesels but I'd imagine compound turbos, big hoss injectors, and a cranked up pump youd be close.

Imo, if you want that kind of power, you would be better off p pumping a 6.7.

Truth be told, a 5.9 12v or 24v, a 7.3 idi or PSD is the most straightforward swap. Other swaps are certainly do-able, but will require more modification and cost a good bit more.

Just curious, why put a 6.7 cummins? Im not super cummins savvy, but last ive heard is the heads like to walk about 200k and the 68rfe isn’t much better of a trans, which leaves the manual and the Aisin HD auto.

Anywho, lets see you do it! I want to see the end result!

Here’s my side notes if you care to read:
a 6.7 cummins will be a heckuva fit. The radiator alone goes from darn near the bottom of the bumper to the hood. So does the intercooler as I recall. adding in the condensor, power steering and trans coolers, its a big front stack of cooling equipment. Its the loosest fit of the big 3.

I know this, because collision repair is my livelihood. The 6.7 psd and 6.6 duramax are even more cramped.

So, just my guess here, but any of the modern diesels plagued by emissions and fancy tech, will require some serious under the hood mods and changed to support structure.

Alright it looks like I'll just go with a 12v cummins. Was thinking of using the 6.7 for all the extra low end torque but it looks like that places a lot more stress on everything. I plan on using an eaton fuller rto 6610 so I should always be able to keep the 12v in its rpm range

 

[79jasper]

I would start with a 24v.
