Swapping a 6.7 Cummins into a second-generation Dodge Ram is a popular modification among truck enthusiasts, offering a significant power upgrade and enhanced performance. This comprehensive guide delves into the complexities, challenges, and rewards of this ambitious project. We'll cover everything from initial planning to final installation, ensuring you're well-equipped for this demanding undertaking.
Why Swap a 6.7 Cummins into a 2nd Gen Ram?
The allure of a 6.7 Cummins swap lies in the substantial power and torque increase compared to the stock engines found in 2nd generation Dodge Rams. The 6.7L Cummins, known for its reliability and robust construction, offers a significant performance boost, transforming the driving experience. This upgrade isn't just about horsepower; it's about the sheer pulling power and improved towing capacity that makes these trucks legendary.
What's Involved in a 6.7 Cummins 2nd Gen Swap?
This isn't a weekend project; it's a significant undertaking requiring considerable mechanical expertise, specialized tools, and a significant time investment. The complexity arises from the numerous components requiring modification or replacement to ensure compatibility. Key areas to consider include:
- Engine Mounts: Fabricating or sourcing custom engine mounts is crucial for proper engine placement and alignment.
- Transmission: Selecting and adapting a suitable transmission, likely an automatic, is a critical step. Consider the torque capacity and overall compatibility.
- Wiring Harness: Extensive rewiring is almost always necessary, requiring a deep understanding of electrical systems.
- Exhaust System: A custom exhaust system is vital, tailored to the new engine's dimensions and output.
- Fuel System: Modifications to the fuel system might be required to accommodate the 6.7's higher fuel demands.
- Cooling System: The increased heat generated by the 6.7 Cummins requires a more robust cooling system. This might involve upgrading the radiator or adding auxiliary cooling components.
What are the common problems encountered during a 6.7 Cummins 2nd Gen Swap?
Several challenges can arise during a 6.7 Cummins swap into a second-gen Dodge Ram. These often stem from the significant differences between the two generations and their respective systems.
Finding Suitable Parts: Sourcing all the necessary parts, especially custom-fabricated components, can be time-consuming and expensive. Many parts will require specialized fabrication or modification.
Wiring Harness Complexity: Integrating the 6.7 Cummins' sophisticated electronic systems into the older truck's wiring harness is extremely demanding and often requires professional-level electrical expertise.
Unexpected Fitment Issues: Even with careful planning, unexpected fitment issues are common. This necessitates problem-solving and potential modifications on the fly.
What are the cost implications of this swap?
The cost of a 6.7 Cummins 2nd gen swap is substantial and highly variable. Factors such as the condition of the donor engine, the level of custom fabrication required, and the cost of professional labor significantly influence the overall expense. Expect a significant investment, ranging from thousands to tens of thousands of dollars, depending on the scope and complexity of the project.
How long does a 6.7 Cummins 2nd Gen Swap take?
The time required for this undertaking is considerable, ranging from several weeks to months, depending on your mechanical skills, access to tools and parts, and the complexity of unforeseen issues. Plan for a substantial time commitment and factor in potential delays.
