Performance & Application

The GTX4202R is engineered for high-output builds that require a large-frame compressor housing paired with a high-flow turbine section. Its ball bearing core design supports quick, efficient response for a turbo of this size, while the built-in ported shroud helps extend the compressor map for improved anti-surge characteristics. This configuration is best suited for serious performance and race applications where massive horsepower support is the priority. The V-Band inlet and outlet turbine housing design supports efficient exhaust flow for builds pushing well beyond four-digit horsepower figures.
