The 6.7 Cummins engine, known for its robust power and reliability, is a popular choice for enthusiasts looking to upgrade their trucks. Swapping a 6.7 Cummins into a second-generation Dodge Ram (often referred to as a "2nd gen swap") is a significant undertaking, but the results are undeniably impressive. This guide will delve into the intricacies of this popular engine swap, addressing common questions and providing valuable insights for those considering this project.
What's Involved in a 6.7 Cummins 2nd Gen Swap?
A 6.7 Cummins swap into a 2nd generation Dodge Ram (1994-2001) is a complex project requiring significant mechanical knowledge, tools, and resources. It's not a weekend project; expect to dedicate considerable time and effort. The core components you'll need include:
- The 6.7 Cummins Engine: Sourcing a used or rebuilt engine is crucial. Consider the year and condition carefully, as compatibility can vary.
- Transmission: The transmission must be compatible with the 6.7 Cummins. This often involves a significant upgrade, potentially requiring a custom adapter or a complete transmission swap.
- Engine Mounts: Custom engine mounts are almost always necessary to secure the 6.7 Cummins in the 2nd gen Ram's engine bay. These are often fabricated or purchased from specialized vendors.
- Wiring Harness: The factory wiring harness from the 6.7 Cummins is incompatible with the 2nd gen Ram's electrical system. A custom harness or extensive rewiring is required. This is often the most challenging aspect of the swap.
- Exhaust System: A custom exhaust system will likely be needed to accommodate the larger 6.7 Cummins.
- Cooling System: The 6.7 Cummins requires a more robust cooling system than the original engine. This may necessitate upgrades to the radiator, hoses, and water pump.
- Fuel System: The fuel system needs careful consideration, often requiring adjustments or upgrades to accommodate the higher fuel demands of the 6.7 Cummins.
What are the Benefits of a 6.7 Cummins 2nd Gen Swap?
The primary benefit is a substantial increase in power and torque compared to the factory engine options for the 2nd gen Rams. The 6.7 Cummins offers a significant jump in performance, making the truck far more capable for towing and hauling. This upgrade can dramatically enhance the truck's overall driving experience.
How Much Does a 6.7 Cummins 2nd Gen Swap Cost?
The cost of a 6.7 Cummins swap varies greatly depending on the condition of the used engine, the chosen components, and the level of professional assistance required. You can expect to spend anywhere from $10,000 to $30,000 or more, depending on several factors. Labor costs alone can be significant.
What are the Challenges of a 6.7 Cummins 2nd Gen Swap?
The swap is mechanically demanding, requiring expertise in various automotive systems. The biggest challenges are typically:
- Wiring Harness Fabrication: This is often considered the most complex part of the swap, requiring specialized knowledge and potentially custom fabrication.
- Custom Fabrication: Various components may require custom fabrication or adaptation, which adds to the project's complexity and cost.
- Finding Parts: Sourcing specific parts for the swap can be challenging and time-consuming.
Is it Worth it to Swap a 6.7 Cummins into a 2nd Gen Dodge Ram?
This depends entirely on your mechanical skills, budget, and desired outcome. If you're seeking a significant power upgrade and are prepared for a challenging project requiring significant time and resources, it can be a rewarding endeavor. However, the significant investment and complexity make it unsuitable for many. Consider carefully whether the benefits outweigh the challenges and costs.
Where Can I Find Parts and Resources for a 6.7 Cummins 2nd Gen Swap?
Online forums and specialized vendors offer parts and resources. Research thoroughly before committing to purchases, as quality and compatibility can vary significantly. Engaging with experienced individuals within the automotive community can be invaluable.
Are there any legal considerations for a 6.7 Cummins 2nd Gen Swap?
Emissions regulations vary by location. Ensure your modified vehicle complies with all local and state regulations. Improperly completed swaps could lead to legal issues. Thoroughly research and understand emissions compliance in your area before undertaking the project.
This guide provides a starting point for those considering a 6.7 Cummins 2nd gen swap. Thorough research and planning are essential for a successful outcome. Remember, this is an advanced automotive modification; seek professional help if you lack the necessary expertise.
