*To ensure accuracy on 2004 models it is recommended that you check your build date. Any truck built prior to 9/29/03 will require a 2003 turbo.
The Garrett 777469-5001S GT3788VA Turbocharger is a must have for any 03-04 6.0L Powerstroke owner that wants to get more out of their truck. Featuring the Garrett patented Advanced Variable Nozzle Turbine (AVNT) design for increased compressor flow and boost response. This turbocharger also utilizes nine movable vanes which significantly increase turbine efficiency and improves engine performance from idle launch through peak torque.

Designed as a “drop-in upgrade”, the GT3788VA retains use of factory components such as engine electronics, mounting pedestal and requires no additional modifications to your factory exhaust system. Utilizing a larger compressor wheel the GT3788VA turbocharger will increase your maximum power range while supporting up to an additional 175HP.  

While this turbocharger is suitable as a replacement for factory equipment, it is highly recommended that additional fueling upgrades such as aftermarket tuning are installed or already in use. Turbocharger comes with cast finish housing and will require Turbo Bolt / O-Ring Kit for installation.
