Performance & Application
Built on Garrett’s large GT42R frame, the GTX4202R is designed to support extreme horsepower levels while maintaining strong compressor efficiency across a wide operating range. The ported shroud compressor housing helps resist surge at the edges of the map, allowing this turbo to deliver both response and high-end flow capability. This unit is suited for builders targeting serious power goals who need a compressor and turbine combination capable of handling significant boost and airflow demands. The V-band inlet and outlet configuration on both the compressor and turbine housings supports clean, efficient plumbing for high-performance turbo system builds.
