Industrial Injection 227448 SX-E Gen Style Single Turbo Kit Cummins A/R - S300 64/74 2nd 5.9L 1.0

The Industrial Injection 227448 is a complete S300 SX-E 64/74 Single Turbo Kit built for the 5.9L Cummins diesel engine. Center-mounting the S300 SX-E turbo on a high-flow T4 manifold in a 2nd Gen style configuration, this kit revises the factory offset turbo placement by centering the turbo on the head between cylinders three and four — delivering more balanced airflow across all cylinders.

The Borg Warner SX-E platform is purpose-built for diesel performance. Unlike modified S300 or S400 units, the SX-E is engineered from the ground up to deliver substantially more airflow and quicker spool-up compared to non-SX-E counterparts. This specific kit comes configured with a 64/74 compressor wheel and a 1.0 A/R turbine housing.

Key Features:

• S300 SX-E Turbocharger — purpose-built for diesel performance with improved airflow and faster spool
• 64/74 Wheel Sizing — rated for up to approximately 650 horsepower
• 1.0 A/R Turbine Housing — T4 flange, single scroll configuration
• 360-Degree Thrust Bearing — upgraded internals for maximum durability under high-load conditions
• Forged Milled Wheel (FMW) — precision compressor wheel for superior performance and reliability
• High-Flow T4 Manifold — 2nd Gen style center-mount design for balanced cylinder airflow
• High-Flow HX40 Downpipe — included to maximize exhaust flow
• Lower EGTs — reduces Exhaust Gas Temperatures for safer, more efficient operation
• Complete Ready-to-Install Kit — everything needed for a straightforward bolt-on installation
