|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.
- Retains Factory Electronics
- “Drop-In Replacement”
- Supports An Additional 175HP
- Requires Turbo Bolt/ O-Ring Kit (See Below)
*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.
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.

I upgraded my stock Turbocharger to the Garrett PowerMax. This is a great upgrade, but it will not operate correctly with just the stock program. This turbo needs a performance tune. I purchased the SCT Flash Tuner which fixed the "Turbo Lag" under the stock program.
