I'm not sure which forum to ask this question.Newbe here.But here it goes.I have a low mi 99 Dodge 1500 4x4 club cab auto with the 5.9L gas and 3.55 LS rear options.I have owned it for a few years now and love except I want to go diesel to run bio-diesel.It would cost me upwards of $6-10k to get a diesel equal.My thought is putting the 4BT into it.I don't need the power of the 5.9 6B diesel or a 3/4 ton.Just the ability to run bio-diesel.I'm a welder so the fit ups are not my concerns.Its the bolt ups and electronics.What might I have to do to convert my 5.9 gas to the 4BT.IE like vacume for brakes,Would my tranny bolt to Dodge adapters on the 5.9 6Bs,dose my auto need vacume,What about the electronic that exist for the gas and what would be needed for the diesel.I would also have concerns about the same or newer year of engine replacement requirement for engine swaps.what 4B was offered in 99 and in what(doner vehicle) step van or something.I figured I could sell the gas engine afterwards to help pay for the swap.If this would be better in another form please let me know.Thanks

 

I have actually looked into this.

Thigs to consider.

1) Purchase of a 4BT - It's not going to be cheap. You need to find one that came out of a vehicle. One out of a piece of equipment may work, but I'm weary of how the injection pump is calibrated as these are made to run at a constant RPM.

2) The easiest way to install it would be to get a NV 4500, NV5600 or auto out of a 6BT cummins dodge. Then you have a transmission, and T-case that will work. You will also need the engine adapter that unbolts from the back of the 6BT depending on the application you get the engine from. Engine mounts should be easy. You may be able to re-use your radiator, should be plenty of cooling. The only problem will be hoses. Worse case, get a radiator out of a 2500 diesel.

3) Fuel - Bypass the electric furl pump in the tank. Besides that, very straight forward.

4) Misc - If you add an intercooler, you need to look to see if the radiator support is different between yours and a Dodge/cummins truck, if so the best thing to do is swap core support and intercooler from donor truck, or get them new. At that point intercooler piping should be easy.

Looking in my service manual, there are quite a few 4BT's that put out over 125 HP and well over 300 LB/FT torque

I though it was here, but there was a guy who did install one in a Jeep, think it was a J10 or similar. You may want to do a little looking for that.

Hope this helps.
