Im just curious:

How many people in here (besides myself) have attempted to or have done a Cummins 4BT or 6BT swap in a Dodge Dakota.

Post links, and if it is yours say "I HAVE" and post a link.

Thanks,

Rob

Does it count that I'm in the process of gathering parts? Got the engine, adapter plate, bellhousing (No NV4500 as of yet, how hard is it to convert 2wd to 4wd?), flywheel, and some motor mounts off a 6bt.

Wish I was a little farther along but I'm in no huge rush. When I get all my parts then I will be looking to stuff the ol 4bt into the engine bay.

2001 Dakota Extended cab 4x4 SLT on 33" MTZs.

Scranton is pretty close to me... Im about 10min away from Grove City, PA.

I am in the process (90% done) of putting a 4BT in my Durango (same mechanicals and engine bay as a Dakota). A 4bt is a lot of work, but is quite possible in a Dakota/Durango. I would NEVER attempt a 6b without starting from the ground up. Even the Sidewinder project had to eliminate the stock heater assembly because the engine pushed the firewall back into the dash. The 3 big issues I see with the 6b is the stock front suspension (ball joints and steering parts don't last long with the stock engine); the length of the motor requiring the firewall to be pushed back 12"+; and the strength of the stock frame.

The 4bt is a very tight fit in the stock engine bay, but would be a good match to the Dakota/Durango's size and weight.

On another note, I really don't see the point of putting a 6b in a Dakota, other than bragging rights that you managed to do it (which is always fun!). A Dakota can't safely tow enough to require that much torque, and the frame can't handle harnessing that much torque even during quarter mile runs. On the other hand, a 4bt would be great for towing a 5000-7000 lb. trailer behind a Dakota or Durango, should get high 20's or into the 30mpg range with the properly matched drivetrain, and will move a Dakota along with a good bit of spirit.

But it would be fun to see a 6b powered Dakota for the street (besides the tube-frame, race car close Sidewinder).

I dont know if you read my begining thread or not but I (we) did put a 6BT Cummins into a Dakota.

Let me just say a few things about your post.

I didn't move the heater assembly, and I didnt move or modify the firewall. I did however modify the stock suspension actually we cut it ut and installed a solid axle suspension with 8 lug axles.

My truck is rated at aprox. 350-400 hp and 800-900 ft lbs of tq, and im pushing 45 lbs of boost. I am running a 38" tire and drive the truck hard enough to break my transmission and i have been doung this for 3 yrs now. I have never had a issue with the frame not being strong enough and i inspect it regularly.

Im sorry if I come off like a smarta$$ I did not mean to sound that way. I just really bothers me when people say things CANT be done.

BTW here is my myspace with all of the pictures:

It would be great to see you up there. Someone with a swap

My first voyage other than around town was from Scranton to Reedsville WV for a DHRA truck pull (which I didnt pull in) and than back to Carlisle for the all truck nationals.

mine's far from finished, and it's certainly not pretty, but if it works, I should be there.

Hey everyone I have an update:

I just spoke to Peter at the Petro and we have the back room reserved for ourselves for 35-40 people and anytime after 12:30. You can either order off the menu or get the buffet. Peter also told me they will put the TV's on for any of us that want to watch the games

I would show up but I think you might insult my STOCK 12v. Also if I did want to make it I don't think my truck would get me over the steep 81 hills:(

I come from a hotrodding background, and I think your truck is just sweet!! Overpower to the point of rediculous is my favorite hobby; I have an S-10 with a 700HP turbocharged/injected smallblock and a 1949M Farmall puller that is turbocharged and pushing 500HP in the factory block.....factory rating was 43HP:D:boom:. The 6BT chevy isthe toy hauler.

Thanks for the compliment I really do appriciate it.

Their isnt a whole lot of room left over at all in fact their was no room for the battery under the hood so we had to mount it under the rear of the truck.
