Moving your 6.7L Cummins to a second-gen turbo layout? This PSC package pairs the Smeding Diesel S400 of your choice with a three-piece T4 exhaust manifold and the piping to put it all together.
What comes in the box
- Smeding Diesel S400 turbocharger and three-piece T4 manifold
- 4-inch downpipe and 5-inch intake with air filter
- Intercooler piping, turbo oil feed and drain lines, and installation hardware
Choose your setup
Start with your truck’s model year so you get the correct piping. Select an exhaust housing, then choose your turbo and either the standard bearing or the 360° thrust bearing upgrade. Smeding recommends the 1.00 A/R T4 housing for the 6.7L Cummins and advises against the 0.90 A/R on this engine.
Want help sizing the turbo? Contact PSC with your model year, injector size, power goal, and what you tow.
