Cummins QSB 4.5 Swap in Dodge 1500 1st cold start

30 F start on dodge 1500 repower. No grid heater or block heater

[@kuhndog-1196]

Do you still have the truck? How does it do on the road? Also what is the transmission setup? Kicking around the idea of throwing one in my 99 Durango.

Hi, Matt, nice job! Could you please send me the wiring from the pedal to the ECU plug. Six wires. Thanks Ron

[@rileykirk11]

good choice of batteries

[@jaredalderson1977]

What ecu are you using? Did you get a doner truck like a bread truck or something and wire it to the dodge? Or is there a standalone ecu available? Also, what software are you using to change engine calibrations...are you just loading different factory calibrations onto the stock ecu, or are you actually manipulating the parameters yourself, like efi live, where you can adjust timing, fuel pressure, ect. Thanks for your help, cool swap!!

How much did you spend to have this done and where and how much . I’m really wanting to Dirksen swap my 1500

[@mattmatz374]

With buying truck....16k. I did all the work minus transmission adapter

[@shanereaves3797]

Hi Matt. I'm not sure if you are still on here but thought I would give it a shot. I have pulled my 4.5 from a generator set along with the CM850 ECM. I will be installing into a 1977 F250 4x4 and mating it to a Ford E4OD transmission using Phoenix adapter. My friend is a Service Supervisor for Cummins in my area and we are trying to figure out which calibration to program my ECM with. I would like to keep it operating on a 12 volt system which is where its at with the Generator setup. Can you give me any help with which calibration to use? Thank you.

[@jonnyjunglejuice8672]

this is my dream combo. would you do it again? anything to be aware of? what kind of mileage are you getting? is it 2wd or 4x4? have you tweeked the motor?

[@mattmatz374]

+Jonny Junglejuice Yes Would do it again on a different vehicle. This swap need custom oil pan. Was able to use 12V Mounts. There was considerable hacking to get it to work. MPG so far have been 20 to 23 MPG. Not Great but not terrible. Pulled a 7,000lb wood chipper down I80 at 70 MPH in overdrive with no problems.

[@junglejonny1000]

+Matt Matz what year truck did you put it in? is it 2wd or 4x4? can you give us things in particular to watch out for? If you ever want to sell your truck, I want to buy it. Are you using the allison 1000? have you tweaked the engine at all?

[@mattmatz374]

+junglejonny1000 2001 Ram 1500 4x4. Takes special transmission adapter from SAE Housing to Dodge 47RE bolt pattern. Trans is a mild built 47RE with billet converter. 17k miles so far no issues. Truck PCM is still controlling transmission.

[@mattmatz374]

+junglejonny1000 Engine is at Stock 158HP/420 Torque calibration. Was at 170/460. Took down for better fuel mileage. Right now truck is not for sale. If had to sell would be 25k for time and what I have in it.

[@junglejonny1000]

+Matt Matz where did you get the trans adapter? I thought it was the SAE #3 specific for only this engine because of the rear gearing on the motor instead of front gearing like the dodge's. Kind of disappointing that you are not getting better fuel mileage. Are you running big tires, low axle ratios or something that would pull the mileage down significantly? I would think that you would have changed the axle ratios and the stall on the torque converter with this motor right? Might as well go to common rail 6bt and get a lot better mileage and power do you think? There is a guy on youtube that put an old rotary pumped 4bt in an f150 that says he gets like 35-40 mpg. I thought that the ISB 4bt would get about that and be quieter and such, I guess I will have to rethink this.

[@trentdawg2832]

Is that the same as a 4bt

[@mattmatz374]

Not really. It is a rear gear train version. So lot less adapter selection

[@OGWhinnyBaby29]

This one has more torque.
