Swapping a 6.7 Cummins into another vehicle is a popular project among diesel enthusiasts, offering a significant power upgrade and robust reliability. This guide delves into the complexities of a second-gen 6.7 Cummins swap, covering everything from feasibility to potential pitfalls. We’ll address common questions and provide insights to help you navigate this ambitious undertaking.
What Vehicles Are Suitable for a 6.7 Cummins Swap?
The feasibility of a 6.7 Cummins swap largely depends on the recipient vehicle. Larger trucks and SUVs with substantial frame strength and ample space are ideal candidates. Smaller vehicles may present significant challenges due to size constraints and the considerable weight of the engine. Popular choices include older Dodge Ram trucks (though they already often have a Cummins), Ford Super Dutys, and even some custom-built projects. Careful planning and consideration of the recipient vehicle's dimensions and structural integrity are paramount.
What Year 6.7 Cummins Is Best for a Swap?
While any second-generation 6.7 Cummins can theoretically be swapped, certain years offer advantages. Later models often benefit from improved emissions systems and potentially more readily available parts. However, newer engines might require more extensive modifications to integrate them into older vehicles. Consider your budget, the availability of parts, and the complexity of the wiring harness when choosing a donor engine. Researching specific years and their associated quirks is crucial for a smooth swap.
How Much Does a 6.7 Cummins Engine Swap Cost?
The cost of a 6.7 Cummins swap varies significantly depending on several factors. The price of the donor engine itself, the required modifications, the labor involved, and the necessary supporting components all contribute to the overall expense. Expect a substantial investment, potentially ranging from several thousand to tens of thousands of dollars, depending on the scope of the project and your level of DIY involvement. Budgeting meticulously is essential, considering unexpected costs and potential complications.
What Transmission Is Compatible with a 6.7 Cummins?
Selecting a compatible transmission is critical for a successful swap. The 6.7 Cummins is typically paired with various transmissions, including the G56, the 68RFE, and the Aisin AS69RC. Compatibility depends on the specific year of the Cummins engine and the recipient vehicle's chassis. Improper transmission selection can lead to significant mechanical issues, so thorough research and expert consultation are crucial.
Is it Difficult to Swap a 6.7 Cummins?
A 6.7 Cummins swap is undoubtedly a challenging project, requiring extensive mechanical knowledge, specialized tools, and significant time commitment. It's not a job for novice mechanics. The complexity involves engine mounting, custom fabrication, wiring harness integration, exhaust system modifications, and potentially significant drivetrain alterations. Seeking guidance from experienced diesel mechanics or joining online forums dedicated to engine swaps is highly recommended.
What Are the Legal Ramifications of a 6.7 Cummins Swap?
Legal considerations concerning emissions compliance vary by region. Modifying a vehicle's engine can impact its legal operation, particularly regarding emissions standards. Be sure to research and comply with all local, state, and federal regulations to ensure your swapped vehicle is street legal. Failing to comply can result in penalties and legal issues.
Where Can I Find Parts for a 6.7 Cummins Swap?
Parts sourcing is a crucial aspect of any engine swap. Several avenues exist, including salvage yards, online retailers specializing in diesel parts, and Cummins dealerships. Carefully research and select reputable suppliers to ensure you receive quality components compatible with your specific swap. Having a reliable source for parts will minimize delays and frustrations during the project.
This comprehensive guide offers a starting point for planning your 6.7 Cummins second-gen swap. Remember, meticulous planning, expert consultation, and a realistic budget are essential for success in this complex and rewarding undertaking. Always prioritize safety and adhere to all relevant regulations throughout the process.
