Talking 4BT Cummins 3.9L in 1998 Dodge Dakota

I found a hell of a good deal of a Dodge Dakota with a 4BT cummins in it for 5 Grand from a dealership... seems like they don't know what they have... All of it looks to be in great condition

I am wondering, from the experts, what the MPG on the truck would be, estimated?

Torque/HP?

If I wanted it to have some (okay maybe a lot) of get up n' go, what would I need to do?

I believe the truck is 2WD, and if you know me, im gonna sink a truck. How much would it cost, approximately, for a 4x4 conversion?



Any help would be greatly appreciated...

i know many people that post on here that Im sure will help me out in person, but the more advice and knowledge the better...

I'll keep yall posted on what I find out about the vehicle, mileage, everything... thanks!

More than likely has a VE pump on it, so factory rating is probably in the 130hp range, I think. Still learning the 4bts myself.

Mileage, I'd imagine easily mid 20s, if not possibly pushing 30 depending on numerous factors of course.

Mods, anything done to a 1st gen 89-93 Dodge can be done to the Dakota.

If it's in good shape, get it. Throw up some pics to

Here's some pics - see attached. I also noticed it has banks diesel emblem on the side, you can see it in the pic... maybe that means it has some unknown mods??

Also, what would yall suggest would be the mileage cut-off? I mean, only get it if it has less than ____ k miles... ?

I doubt banks makes anything for the 4bt. Looking at the light I'd be willing to bet it was an escort truck and it probably has a ton of miles. Any way of telling how long the 4bt was in it?

My buddy had a 70's f100 with a 4bt swap and a 4 speed manual. It got 23-25 mpg usually, but it was out of steam at 75mph, so it was running on the governor most of the time. I wouldn't expect less than mid 20's to high 30's out of that setup, depending on gears.

4x4 depends on you ability to fabricate, or the feasibility of swapping in a stock IFS setup. For the weight I'd want a straight axle up front, but thats just me.

No I did not...

the dealership says the truck's speedo says it has 260k miles

... But on the phone the guy was saying the truck had 170k miles.... ??

He said the swap itself is about a year old... buutttt...

They don't know how many miles the motor itself has.

But the guy I talked to wasn't too knowledgeable whether it was even a 4BT or what a 4BT even is...

I wouldn't be too concerned about miles. Have the suspension looked at and checked over real good, maybe a mechanic you know yourself over the dealers. Other than that, miles on the engine is almost a moot point as it'll last dang near forever. It would appear that it was in a construction fleet, either as a supervisors ride, interior looks a little clean for a pilot, or maybe an electric company, or something along those lines.

Any idea what trans is in it?

Doesn't surprise me a salesman doesn't know much about the engine, as they get training from the factory on whats in the vehicles they sell and many still can't get it right.

id have to look at it to be sure but if it look to be in good shape 260k wouldnt bother me. With my swap i usually average about 25 i have gotten 30mpg on a long highway run.

any pics of under the hood. need to see the kind of work the person put into the swap.

I was thinkin' the same thing!!! hahaah...



I dunno though, seems like without the 4x4 it might just be useless to have the 4BT.... 4BTs are great lil' mud truck motors... but there wont be much muddin with 2wd...

And if I can't get a truck I can mud, then I want one thats gonna be fast... and I don't think the 4BT would cut it?

I have a couple friends who are mechanics; I may bring him to check it out...

I'll give them another call tomorrow and ask them some more questions... any suggestions on questions??
