Performance & Application

Built on Garrett’s large-frame GT42R platform, the GTX4202R is engineered for builders targeting massive power output on high-performance engine platforms. The ball bearing core provides sharper transient response and improved spool characteristics compared to traditional journal bearing designs, while the high-flowing compressor housing and TiAL stainless steel turbine housing support sustained top-end power delivery. The built-in ported shroud design improves compressor stability and resists surge under aggressive boost conditions. This turbo is best suited for high-horsepower builds where both flow capacity and bearing durability are critical.
