DIESEL CUMMINS CONVERSION Transmission Adapter KITS | G FORCE
A diesel Cummins conversion involves the swapping of a Cummins diesel engine into another vehicle. Many people perform a Cummins conversion to increase the efficiency and longevity of their vehicle. They might also revive a vehicle with a broken-down engine. Some common terms you may hear surrounding these conversions include "Fummins" and "Chummins.". These refer to Cummins to Ford conversion or Cummins to Chevy swap, respectively.
At G Force Performance Products, we offer a variety of diesel Cummins swap transmission adapter kits, so that you can complete your Fummins, Chummins, or Cummins Allison conversion projects.
Can I swap any engine into any car?
Engine swapping is a complex process, especially if you convert an engine into a different make vehicle. It ultimately depends on how much money you are willing to spend. If you have the materials, time, and money, the possibilities are virtually endless.
However, there are many regulations to follow if you want the vehicle to remain street legal after the swap. Thus, we suggest consulting with a reputable engineer before performing an engine conversion. An engineer can analyze your project and desired outcome to confirm whether it will function optimally and maintain street legality.
How much does a diesel Cummins conversion cost?
Prices can vary from roughly $5,000 to $10,000 or more. It all depends on what engine you choose, where you are swapping it, how you are swapping it, and the amount of labor necessary to complete the project.
Why Perform a Diesel Cummins Conversion?
Cummins diesel engine conversions are becoming increasingly popular in recent years. There are many ways to revive and enhance vehicles like 4-wheel-drive SUVs and trucks. The process has also become more affordable over time, but what are the concrete benefits of performing a Cummins engine swap? Is it really worth the investment? Here are some common reasons why people decide to swap for Cummins diesel engines:
Cummins diesel engines can provide significantly more torque than the typical gas engine. As a result, you get faster speeds and more towing strength. Truck owners can easily get immense value from a Cummins swap. A Cummins diesel engine will turn your vehicle into an unstoppable powerhouse.
Superior Reliability and Longevity
Diesel engines have proven their ability to outlast standard gasoline engines easily. They have to meet higher design standards because the parts need to facilitate the engine's combustion cycle. Diesel fuel also offers better lubrication than gasoline. When properly maintained, diesel engines can last two times longer than their gas engine counterparts.
Furthermore, a Cummins diesel engine can last up to 500,000 miles and sometimes more! It is not uncommon for a diesel engine to outlast the vehicle itself. With a Cummins engine, your vehicle will last for many years and even maintain its value.
Improved Fuel Economy
The average diesel engine offers much better fuel efficiency than standard gas engines. In particular, Cummins engines offer very high fuel economy. Diesel fuel itself also provides more energy than regular gasoline. As a result, you can save a lot of money in the long run. You will not have to refill your tank as frequently as you would with a gas engine. That money begins to add up over time, especially with the longevity of a Cummins engine.
Easy to Modify
Many people who perform diesel engine conversions are already interested in car modifications and find that Cummins diesel engines are easily modified. With how often new mod and upgrade options arise, a diesel engine can fulfill the needs of even the most adamant hobbyists. Furthermore, resources for modifying Cummins engines are readily available so that you can perform upgrades at your leisure. With a Cummins conversion, you can build the powerful diesel truck you always wanted.
Diesel Cummins Conversions with G Force Performance Products
Many unique advantages that come with swapping a Cummins diesel engine into your vehicle, and we can help you with your conversion project. The attractiveness of the Cummins swap is evident as car enthusiasts pursue aftermarket conversion alternatives to repower their trucks. Automotive aftermarket manufacturers like G Force provide parts for various engine to transmission adapter kits and other components for your swap.
Ford Cummins Swap Transmission Adapter Kits
Our popular Cummins to Ford conversion kits include the 1989-2002 Cummins to Ford 5R110 Adapter Kit (GF-F5R110-S) and the 2003-2017 Cummins 6BT to 2006-2017 5R110 Ford automatic transmission adapter kit (GF-F5R110-SL).
These kits always contain an adapter plate and flexplate. The G Force GF-F5R110-SL shown here also comes with mounting hardware. Instead of angled like some OEM applications, G Force adapters allow you to position the transmission straight. Both kits also require a Ford Powerstroke starter. The 6.4 L starter is recommended. However, the Ford 6.0L Powerstroke starter is an option, although, with it, some bellhousings need additional interior clearance.
