Swapping a 6.7 Cummins into a second-generation Dodge Ram is a popular modification among truck enthusiasts, offering significant power and torque upgrades. This comprehensive guide dives deep into the complexities of this swap, addressing common questions and concerns. We'll explore the technical aspects, potential challenges, and considerations for a successful installation.
What are the Benefits of a 6.7 Cummins Second-Gen Swap?
The allure of a 6.7 Cummins swap lies in its substantial power and torque increase compared to the factory engine. This translates to significantly improved towing capacity and overall performance. The 6.7 Cummins is also known for its durability and reliability, promising a long-lasting upgrade for your truck. The increased power output can also enhance your truck's resale value, depending on the quality of the swap.
What Year Dodge Rams are Compatible with a 6.7 Cummins Swap?
This is a crucial question. While the physical fitment might seem possible, a successful swap necessitates careful consideration of the year and model of your Dodge Ram. The second-generation Rams (typically 1994-2002) present unique challenges due to the differences in the chassis, electronics, and overall design compared to later models. It is generally more feasible for models from 1998-2002 but will still require significant modifications. Always confirm compatibility with your specific year and model before beginning the project.
What are the Parts Needed for a 6.7 Cummins Swap?
A successful 6.7 Cummins swap is not a simple bolt-on affair. You'll need a comprehensive list of parts, including the engine itself (obviously!), a suitable transmission (likely a 68RFE or equivalent), a custom engine harness, a new ECM (Engine Control Module) potentially needing programming, upgraded axles and drivetrain components to handle the increased torque, and a modified exhaust system. Don't forget the necessary mounts and brackets to securely position the engine in the engine bay. You will also need a significant amount of specialized tools and possibly specialized knowledge for the job. Consult with a professional mechanic or experienced enthusiast for a complete parts list tailored to your specific truck.
How Much Does a 6.7 Cummins Second-Gen Swap Cost?
The cost of a 6.7 Cummins swap can vary significantly depending on several factors, including the condition of the donor engine, the labor costs (which will be extensive), the availability of used versus new parts, and the complexity of the installation. Expect to invest a considerable amount of money, potentially ranging from tens of thousands of dollars to well over $50,000 depending on how much work is done and the condition of parts used. This is not a project to undertake lightly or on a budget.
Is it Difficult to do a 6.7 Cummins Second-Gen Swap?
This swap is incredibly challenging and should only be attempted by experienced mechanics or highly skilled enthusiasts with extensive experience in automotive engine swaps. The complexity stems from the significant modifications required to accommodate the larger engine, the need for custom fabrication, and the intricate wiring and computer programming involved. Improper installation can lead to serious mechanical issues and even safety hazards.
What are the Common Problems Encountered During a 6.7 Cummins Second-Gen Swap?
Several potential problems can arise during the swap, including clearance issues with the firewall and other chassis components, difficulties integrating the engine's electronic control systems with the truck's existing wiring, and challenges associated with adapting the transmission and drivetrain components. Proper planning and meticulous attention to detail are essential to avoid these issues. Seeking guidance from experienced individuals or online forums is highly recommended.
Can I do this swap myself?
While theoretically possible, undertaking this swap independently is strongly discouraged unless you possess extensive mechanical expertise, specifically experience with diesel engine swaps and automotive electrical systems. The complexity and potential risks involved make it a project best suited to professional mechanics or very experienced enthusiasts with access to specialized tools and resources. Even then, professional advice is highly recommended.
This guide provides a general overview. Always conduct thorough research and seek expert advice before attempting a 6.7 Cummins second-gen swap. The complexities involved necessitate careful planning, sufficient resources, and a high level of mechanical skill. Remember safety is paramount.
