BorgWarner Cartridge S400 75mm (75/96)

This BorgWarner S400 turbo cartridge features a 75mm inducer diameter on the compressor wheel and a 96mm exducer diameter. This specific sizing is key for applications looking to move a significant amount of air, often found in performance diesel or heavy-duty truck builds where increased airflow is needed to support larger engines or higher boost pressures. The cartridge design means it's a self-contained unit, simplifying installation compared to a full turbo assembly.

Built by BorgWarner, a well-known name in turbocharger technology, this cartridge is designed for durability and performance. The compressor wheel is typically made from strong aluminum alloy, balanced to high standards for smooth operation and longevity. The turbine side is built to handle the heat and exhaust flow from demanding engines. This unit is intended as a replacement or upgrade component for specific turbocharger models that utilize the S400 frame size. It's important to ensure your existing turbocharger housing is compatible with this cartridge size.

When considering a turbo cartridge like this, it's crucial to match it to your engine's needs and your overall build goals. Proper fueling, exhaust flow, and cooling are all essential to get the most out of a performance turbocharger and to ensure its reliability. This cartridge is a solid option for those rebuilding or upgrading their forced induction system and looking for a robust, high-volume airflow solution from a trusted manufacturer.
