FAQ
Is this a drop-in turbo?This is a full kit engineered for the 6.7L Cummins. It includes the major hardware, lines, and piping you need, but some builds may require minor trimming or adjustment depending on other installed parts.
Will the .90 A/R spool slowly?Compared to smaller S400 options, the S475 favors mid/top-end power. Proper tuning, a healthy fuel system, and a tight exhaust system help reduce spool time.
What supporting mods are recommended?Head studs, a quality lift pump, EGT and boost gauges, and a T4 manifold. For heavy towing, consider a smaller S400 or a compound setup.
Do I need custom tuning?Yes. To fully realize the S475’s airflow and maintain safe EGTs/drive pressure, custom calibration is required.
