Frequently Asked Questions
Will a second gen swap increase my engine bay heat?
Moving the turbo to the top of the engine bay does bring heat closer to your hood and electrical components. You should use a thick turbo blanket and header wrap to keep those temperatures in check. This protects your paint and nearby wiring from excessive radiant heat.
Do I need to upgrade my injectors for this swap?
You do not strictly need larger injectors to run the kit, but the swap is often part of a larger performance build. If you install a massive turbo, your stock injectors might struggle to provide enough fuel to spool it quickly. Balance your turbo sizing with your fueling capabilities for the best drivability.
Is this swap compatible with all 6.7 Cummins models?
Most kits are designed for specific years, primarily because of changes in emissions equipment and manifold bolt patterns. Always check if the kit specifies compatibility with your year and transmission type. Some kits may require you to delete or relocate specific factory components.
How much power can I expect from a swap kit?
A swap kit itself does not add horsepower, but it allows you to run a larger, more efficient turbocharger. This efficiency leads to lower drive pressure and cooler intake temperatures at higher boost levels. Your total power gains depend entirely on your tuning and fueling hardware.
Can I install this kit in my driveway?
You can complete this installation at home if you have a solid set of tools and a weekend to spare. The process involves removing the heavy factory exhaust manifold and potentially the coolant reservoir. Keep a few extra exhaust manifold gaskets on hand just in case you damage one during the install.
