Performance & Application

This compressor housing is designed specifically for the GT35R turbocharger platform, pairing with the 82mm 56 trim compressor wheel for high-flow performance applications. The T04S frame and larger 4″ inlet sizing support increased airflow demands compared to smaller frame alternatives, making it well-suited for high-horsepower builds where flow capacity is the priority. Since this housing features no anti-surge design, it is best suited for builds where surge characteristics are not a primary concern, such as drag or high-boost applications running a GT35R core.
