FAQ
How much power will the 69/74 SX-E support?With the right fuel, air, and tuning, the 69/74 SX-E is commonly used in 700–850 HP single-turbo builds on 6.7L Cummins platforms. Results vary by altitude, intercooling, cam, and intended use.
Does this kit relocate the turbo to a 2nd-gen position?Yes. It centers the turbo on a T4 manifold in a 2nd-gen style location to improve serviceability and flow.
Will I need custom tuning?Yes. Any major turbo upgrade requires proper tuning and fuel/air matching to manage drive pressure, EGT, and smoke output.
Is additional hardware required?Most installs benefit from fresh manifold gaskets/studs, a quality oil feed/drain, and reinforced boots/clamps. See the Recommended Parts above.
