Industrial Injection 22B418 S475 .90 A/R Turbo Swap Kit for 6.7L Cummins

The Industrial Injection 22B418 is a complete S475 turbo swap kit engineered for the 6.7L Cummins diesel engine. Designed for high-output street and track competition builds, this kit delivers the airflow capacity and hardware needed to support serious power goals in a single, comprehensive package.

Key Features:

• Complete Install Kit — includes everything needed for a clean, professional turbocharger swap
• BorgWarner S475 Turbocharger (P/N 177101) — features twin hydrodynamic journal bearings and an extended tip technology compressor wheel
• 75mm Compressor Wheel with 100mm OD for high-volume airflow
• 83/74mm Turbine Wheel paired with a .90 A/R T4 turbine housing for enhanced spool characteristics
• 100 lbs/min airflow capacity — built for high-horsepower competition applications
• V-Banded Race Cover — minimizes back pressure and contributes to lower exhaust gas temperatures (EGTs)
• Custom S&B Designed Intake — optimizes airflow for improved performance

Turbo Specifications:

• Compressor Wheel: 75mm inducer / 100mm OD
• Turbine Wheel: 83mm OD / 74mm exducer
• Turbine Housing: .90 A/R T4 Twin Scroll
• Max Airflow: 100 lbs/min
• Oil Feed: 1/4 NPT | Oil Drain: Standard S400 flange

Note on A/R Selection: The .90 A/R turbine housing is the tightest ratio in the S475 lineup and is best suited for builds running smaller injector sizes, oversized tires, or numerically lower gear ratios, where increased drive pressure aids turbo spool-up. Injector upgrades are required to maximize spool and overall performance with this kit.
