Garrett GT3582R Super Core (Small Frame)

The Garrett GT3582R Super Core features a 4-inch inlet and 3-inch V-band outlet, a common setup for many custom turbo builds. This is a small-frame turbocharger assembly, meaning it's designed for applications where space is a consideration or for engines that don't require the absolute largest airflow. It's built around Garrett's renowned turbocharger technology, offering a solid foundation for a high-performance forced induction system.

This super core assembly is designed for builders who want to select their own turbine housing and compressor cover to perfectly match their engine's needs. The core itself includes the essential rotating assembly – the turbine wheel, compressor wheel, and the bearings that support them – all housed within the center housing. This approach gives you the flexibility to tune the turbo's response and powerband precisely. The turbine wheel is made from Inconel, a material known for its strength and resistance to extreme temperatures, which is crucial for turbocharger longevity under heavy load. The compressor wheel is forged from aluminum, keeping rotational mass down for improved spool-up.

When building a custom turbo kit, starting with a reliable core like the GT3582R is key. You'll need to source compatible turbine housings and compressor covers that bolt up to the core's specified inlet and outlet flanges. This unit is not CARB approved, so it cannot be legally shipped to California. Always consult with a professional or experienced builder to ensure you select the correct housings and supporting components for your specific engine and performance goals.
