FAQ
What power range can an S471 support on a 6.7L Cummins?With adequate fueling, air, and tuning, S471 builds commonly target high-500s to 700+ HP. Final results vary by altitude, fuel system, injectors, and calibration.
Do I need a T4 2nd-gen manifold?
Yes. This kit is designed around a 2nd-gen center-mount T4 setup. Pair it with a quality T4 6.7L manifold for proper fitment and durability.
Will I lose exhaust brake functionality?
Factory VGT braking is removed when switching to a fixed-geometry S400 turbo. Many customers add a fabricated or inline brake if they need similar functionality.
Is tuning required after installation?
Yes. Custom calibration is required to prevent DTCs, optimize drivability, manage boost, and protect the engine and transmission.
What supporting mods do you recommend?
At minimum: quality lift pump, head studs, intercooler/boots in good condition, and custom tuning. Higher power builds may require injectors and CP3 upgrades.
