Ten years ago, a 2nd gen swap meant piecing together a collection of random hoses and prayer. You spent weeks hunting for parts that barely fit.
Today, you can grab a pre-engineered package that actually makes sense. These kits have turned a weekend of frustration into a straightforward project. Choosing the Best 2nd Gen Swap Kit 6.7 Cumminses is simpler if you know where to start.
Key Takeaways
- Prioritize stainless steel braided lines for oil feeds because they handle high heat better than standard rubber hoses.
- Always check that the intake manifold casting provides sufficient clearance for existing fuel lines to avoid installation headaches.
- Opt for kits that include high quality hardware and gaskets to prevent persistent oil leaks after the job is finished.
- Ensure the coolant bypass components match your specific production year to avoid compatibility issues with the thermostat housing.
- Verify that your grid heater delete or upgrade includes the necessary electrical pigtails to prevent check engine lights.

Frequently Asked Questions
Will a second gen swap kit fit my stock intake horn?
Most kits require you to swap to a second gen style intake horn because the original 6.7 manifold orientation is different. Do not plan on reusing your factory intake piece unless the kit description explicitly states it is compatible.
Do I need to upgrade my tuning for this kit?
Yes, installing a new turbo configuration changes your air-to-fuel ratio significantly. You must update your ECM tuning to account for the increased airflow and to prevent running lean or creating excessive exhaust gas temperatures.
How long does the installation process usually take?
Expect to spend at least 8 to 12 hours on the installation if you have a well-equipped garage. Removing the factory manifold and turbo is often the most time-consuming part because the bolts can be stubborn after years of heat cycles.
Can I use my stock downpipe with these kits?
Almost every kit requires a custom downpipe that is included in the package. The outlet position of a second gen turbo is completely different from the factory setup on a 6.7 engine.
What is the main benefit of performing this swap?
The primary goal is to improve turbo spool time and lower your exhaust gas temperatures. Moving the turbo away from the congested factory manifold area allows for better airflow and helps the engine breathe more efficiently under load.
