FAQ

Q:How many hours does it take to do a conversion? *click here
A: The time it takes to do a conversion depends on the truck, the engine used, the amount of time you have to work on it, and your mechanical skills. We can't tell you exactly, but plan on spending somewhere between 80-200 hours on it. So don't expect to do it on a weekend, but you will be amazed at how fast you will have a Cummins sitting in your engine compartment. The things that slow most projects down are the small stuff. That's why we try to offer most of the parts you will need. Plan ahead, read your instructions, and you should get it done well under the 200 hour mark.

Q: Can I put a Cummins engine in my truck that had a gas engine in it previously? *click here
A: Yes. It's a bit more work and you will have to buy a few more parts like an intercooler and possibly a diesel radiator, but it's worth it.

Q: Can I use my Ford transmission? *click here
A: Yes. We currently make 15 different ADAPTER PLATES that allow you to bolt a Ford transmission up to a Cummins engine (we cover most Ford transmissions).

Q: Are your Ford Cummins motor mounts bolt in? *click here

A: Yes. Our motor mounts are bolt in. They come complete with insulators as well. Our mounts actually locate your engine for you. They will set your engine right where it needs to be side-to-side, up-and-down, and front-to-back, taking the guess work out of engine positioning. Mounting the Cummins engine in your Ford truck with our mounts is actually easier than putting the Cummins engine back in a Dodge truck and even easier than putting the Ford engine back in the Ford truck.

Q: Can I use the stock Ford gauges in my dash? *click here

A: Yes. We sell a "bushing kit" that includes adapters that help you install the stock oil pressure and temperature sensors into the Cummins engine. For the newer trucks these bushings have to be custom machined. The stock tachometer will work with our tach kit, and we have the instructions to help you get the wires all reconnected to your sensors.

Q: Do I need the computer from the Dodge truck? *click here

A: Depends on the year of the Cummins. You do not need the powertrain computer (PCM) off the Dodge truck's fire wall if you are using a 1989-1998 12 Valve Cummins engine as these engines are 100% non-computer controlled.

For the 1998-2002 24 Valve Cummins engine it is possible to run the engine with only the ECM. This computer is located right on the driver's side of the engine. If you want the capability to use OBDII diagnostics, or some brands of tuners, you will need to use the Dodge PCM off the passenger side of the firewall as well. We have instructions to help you with the wiring, or you can send the Cummins and the Ford engine wiring harnesses and we can put them together for you for a reasonable price.

The 2003 and newer CommonRail Cummins engine normally only needs the ECM that is located right on the side of the Cummins engine.

Q: Can I use a 5.9 Cummins engine out of a school bus or other commercial application? *click here
A: Yes. You will need to swap out some of the brackets like alternator, A/C, fan hub, possibly the oil pan, etc...but the engine will work fine. Industrial/Commercial common rail engines usually have a rear gear train, so stay away from those- as we don't make transmission adapter plates for those yet.

Q: What will I do about my Cummins engine turbo coming too close to my Ford truck A/C box when using a Dodge application 12 Valve Cummins engine or a 98-02 24 Valve Cummins engine in my Ford truck? *click here
A: Some guys have flipped their Dodge application 5.9 Cummins exhaust manifold upside down in order to clear the Ford A/C box. This does help give clearance, however it still ends up close to the a/c box and close to the hood too. You will still have to re-clock your turbo housings and rebuild the drain tube. The manifold we sell works much better. It locates the turbo down closer to the engine block and looks much cleaner. It provides about 6" of clearance between the Cummins turbo and the Ford A/C box. It does require an industrial wastegate actuator (or you can just block the wastegate off) and re-clocking the turbo. We sell a flexible drain tube to help get the drain reconnected, and your original supply tube will still work.
