Industrial Injection 227427 S475 2nd Gen Turbo Swap Kit 5.9L Cummins 1.00 A/R

The Industrial Injection 227427 S475 2nd Gen Turbo Swap Kit is a high-performance turbocharger upgrade engineered for the 5.9L Cummins diesel engine. Designed for serious street and track builds, this complete swap kit addresses the core limitations of the factory turbocharger, which is only capable of supporting power levels below 450 horsepower before overspeeding and failing. The factory unit is also poorly positioned on the engine—centered over cylinders four and five rather than three and four—causing uneven EGTs across the cylinder bank. This Industrial Injection kit corrects both issues, improving airflow distribution and repositioning the turbo for better overall engine balance.

When paired with custom tuning and a larger injector set, this S475 configuration is capable of supporting 800+ rear wheel horsepower on the 5.9L platform. The 1.00 A/R turbine housing is the ideal middle-ground option—well-suited for builds running mid-range injectors (around 180 HP), 35" tires, and 3.73 gears, balancing spool response with top-end airflow capacity.

Key Features:

• 75mm Compressor Wheel for high-volume airflow
• 83/74mm Turbine Wheel for efficient exhaust energy extraction
• 1.00 A/R T4 Turbine Housing — balanced spool and top-end performance
• 100 lbs/min airflow capacity
• V-Banded Race Cover for secure, leak-free sealing
• Lower EGTs compared to the factory turbocharger setup
• Complete Installation Kit included for a clean, straightforward install
• Custom S&B Designed Cold Air Intake included
• Injector upgrades required for optimum spool and full performance potential
