AGT 52mm “LE” Turbocharger | Mitsubishi Evo 4-9
The AGT 52mm LE Turbocharger for Mitsubishi Evo 4–9 is a next-generation bolt-on upgrade designed for faster spool, improved airflow, and stronger midrange performance while retaining factory-style fitment.
At the heart of this turbo is AGT’s updated “LE” Leading Edge compressor aero, featuring redesigned blade geometry, a smaller center hub for increased blade surface area, and an integral compressor nut. These refinements reduce rotating mass and improve efficiency, resulting in quicker response and increased flow capacity.
Flowing up to 55 lbs per minute, this turbo is ideal for street and responsive track builds targeting strong torque and reliable horsepower without stepping into oversized full-frame territory.
