Featuring the Garrett patented Advanced Variable Nozzle Turbine (AVNT) design for increased compressor flow and boost response. This turbocharger features a larger compressor trim (52), plus larger GT40 turbine wheel and vanes over the Stage 1 model. The GT4094VA also utilizes nine movable vanes which significantly increase turbine efficiency and improves engine performance from idle launch through peak torque.

Utilizing a larger compressor wheel the GT4094VA turbocharger will increase your maximum power range while supporting up to 575HP with no sacrifice to drivability.

    While this turbocharger is suitable as a replacement for factory equipment, its recommended that additional fueling upgrades such as aftermarket/custom tuning are installed or already in use. Includes turbocharger, adapter cable and installation instructions.

    • Drop-In Replacement
    • Supports Up To 575HP
    • Retains Factory Electronics 
    • 1 Year Warranty

    Note from Garrett regarding shaft play:

    When the Powermax turbo is new, or has not operated for a long period of time allowing most of the oil to drain out, the rotating assembly will move more in the radial direction because there is no oil in the center housing. This condition is normal. As long as the shaft wheel spins freely and the wheels don't contact their respective housings, the assembly will function properly.
