57mm LE Turbocharger

The AGT 57mm LE Turbocharger is a high-performance, stock-frame upgrade designed for Mitsubishi Evo 4-9 vehicles equipped with 4G63 engines. This turbocharger is engineered to deliver a potent combination of strong midrange torque and significant top-end power, capable of supporting builds targeting 500 to 650+ horsepower. At its core, the turbo features AGT’s advanced Leading Edge (LE) billet compressor wheel technology. This design incorporates an updated blade aero profile, a smaller center hub for increased blade surface area, an integral compressor nut, and reduced wheel weight. These enhancements collectively improve spool characteristics, boost airflow efficiency, and provide a more responsive throttle compared to traditional compressor designs. The compressor wheel measures 57x78mm, while the turbine wheel is 58x67mm. It utilizes a durable journal bearing with a heavy-duty thrust bearing for longevity. Customization is a key aspect, with multiple options available for compressor and turbine housings, as well as wastegate configurations. The compressor housing is a 3.25-inch T51R-style anti-surge inlet. Turbine housing options include a 0.77 A/R twin scroll or an AGT 0.96 A/R stainless steel single scroll, the latter offering enhanced durability under high heat and aggressive boost conditions. Wastegate options include no wastegate, a 22 psi internal wastegate, or a 26 psi dual-port wastegate. A high-flow braided oil line is included for proper lubrication.
