Product Description
Unlock serious airflow and lower EGTs with the Industrial Injection S475 2nd-Gen T4 Swap for the 2007.5–2009 6.7L Cummins. This kit moves the turbo to the proven 2nd-gen location and pairs a 75mm compressor with a 1.10 A/R T4 divided turbine housing for strong top-end power and reliable towing performance when properly fueled and tuned.
Fitment
- 2007.5–2009 Dodge Ram 2500/3500 with 6.7L Cummins (ISB)
- Works with most popular aftermarket intakes, intercoolers, and downpipes designed for 2nd-gen T4 swaps
- Truck must be appropriately fueled and tuned for best results
Why a 2nd-Gen Swap?
- Improved exhaust flow from T4 divided manifold location for faster turbine response
- Lower EGT potential under load vs. stock-location setups when matched with proper fueling
- Room to grow—S475 supports high-horsepower street/strip and heavy tow builds (with supporting mods)
Core Turbo Specs
- Compressor: S475 (75mm class)
- Turbine Housing: 1.10 A/R, T4 divided
- Designed for 2nd-gen swap position on 6.7L Cummins

FAQ
What horsepower range can an S475 support on a 6.7L Cummins?With adequate fuel, air, and tuning, S475 2nd-gen swaps are commonly used in high-horsepower street/tow builds. Actual results depend on injectors, pump, intercooler, elevation, and tuning.
Is a 1.10 A/R right for towing?The 1.10 A/R T4 divided housing provides strong top-end flow while maintaining good drivability when paired with proper fueling and tuning. Heavier towing at lower RPM may prefer smaller turbine A/R or a compound setup.
Do I need head studs?We strongly recommend ARP head studs for elevated boost and sustained towing loads. See our ARP selection linked above.
What else should I upgrade?Lift pump, CP3/CP4 fueling, injectors, intercooler and piping, 4"/5" exhaust, and quality tuning/monitoring to keep EGT and drive pressure in check.
