Industrial Injection 227424 S471 2nd Gen Swap Turbo Kit 1.00 A/R 5.9L Cummins

The Industrial Injection 227424 S471 2nd Gen Swap Turbo Kit is a complete, high-performance turbocharger upgrade engineered for the 2003–2007 Dodge 5.9L Cummins. Designed for serious street and track builds, this kit repositions the turbo to the center of the engine — mirroring true 2nd Gen Cummins geometry — to equalize cylinder-to-cylinder airflow distribution and deliver maximum output potential.

The factory turbocharger on the 03–07 5.9L Cummins is centered over cylinders four and five rather than three and four, causing the front cylinders to run hotter than the rear. This kit corrects that placement while also replacing a turbo that is only capable of supporting power levels below approximately 450 horsepower before it becomes a limiting factor. The S471 charger at the heart of this kit flows up to 90 lbs/min and features a 71mm compressor wheel and 83/74mm turbine wheel, paired with a 1.00 A/R turbine housing for strong spool-up characteristics and competitive power delivery.

Kit Features:

• S471 Turbocharger — 71mm compressor wheel, 83/74mm turbine wheel, 90 lbs/min airflow capacity
• 1.00 A/R Turbine Housing — tuned for rapid spool-up and strong mid-to-top-end power
• V-Banded Race Cover — improves performance and simplifies service and installation
• Complete Installation Hardware Kit — everything needed for a clean, professional install
• Custom S&B Designed Cold Air Intake — optimized intake path included in the kit
• Reduced Exhaust Gas Temperatures (EGTs) — improved airflow efficiency keeps EGTs in check under hard use
• Street and track performance oriented design

Important Notes: Injector upgrades are required for optimal spool-up and peak performance with this kit. Custom tuning is strongly recommended for power levels above 700 rear-wheel horsepower. This kit is designed for competition / dedicated race use only and is not legal for on-road or off-road street use.
