Performance & Application
Built with a high-flowing compressor housing featuring a built-in ported shroud for anti-surge protection, the GTX4202R is designed for builders pushing well beyond four-figure horsepower targets. The large frame compressor wheel combined with the divided turbine housing delivers strong exhaust pulse separation for improved turbine efficiency, while the ball bearing core provides sharper response compared to traditional journal bearing designs. This turbo is best suited for high-horsepower applications where V-Band connections and maximum flow capacity are required to support aggressive power levels.
