BorgWarner Turbo S400SX SX 74.5mm (100/83)

If you're looking to significantly boost the power output of your diesel truck or performance gasoline engine, a high-performance turbocharger like the BorgWarner S400SX is a serious consideration. This unit is built for those who demand more airflow and boost pressure than stock components can provide, making it a popular choice for custom builds and serious performance upgrades. It features a 74.5mm compressor wheel and a 100mm turbine wheel, designed to move a substantial amount of air efficiently.

The S400SX series is known for its robust construction and ability to handle demanding conditions. This particular model, part number 179174, is engineered to support significant horsepower gains. The compressor housing features a 4-inch inlet and 2.5-inch outlet, while the turbine housing has a 1.10 A/R ratio with a 5-inch V-band discharge. These specifications indicate a turbo capable of supporting high-flow exhaust and intake needs, crucial for maximizing performance in modified engines. Its well-built design aims for reliability under high boost pressures.

When installing a turbocharger of this caliber, it's essential to ensure your engine's supporting systems are up to the task. This includes proper fuel delivery, engine management tuning, and robust cooling. Because this turbocharger is not CARB approved, it cannot be shipped to California. Always consult with a professional installer or engine builder to confirm compatibility and ensure all necessary supporting modifications are made for optimal performance and longevity.
