Description
The Garrett 777469-5002S GT3788VA Turbocharger is a must have for any 2003-2004 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.
Features:
- Drop-In Replacement
- Retains Factory Electronics
- Supports An Additional 175HP
- Requires Turbo Bolt/ O-Ring Kit (See Below)
- 1 Year Warranty
*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.

Questions and Answers
What is the warranty on the Garrett 777469-5001S PowerMax GT3788VA Turbocharger?
View Staff Answer
Answer
Garrett offers a 1 year / 100,000 miles warranty
The XDP Race Fuel Valve prevents fuel from being returned to the tank when the pressure release valve is opened due to fuel rail pressure increases. Many high performance electronic tuning devices raise the fuel rail pressure resulting in P0087 & P1011 codes on Cummins engines and P1093 codes on Duramax engines. Once installed you should notice the codes no longer being displayed and no more loss of power.

Will this turbo increase my milage?
View Staff Answer
Answer
The Garrett PowerMax GT3788VA turbocharger is machined differently than your OEM turbo and has a much lesser likelihood over the factory turbo.
The Garrett GT3788VA Turbocharger will increase turbine efficiency as well as engine performance. Beings the turbo is larger than stock we highly recommended that additional fueling upgrades such as aftermarket tuning be installed or already in use. With the proper supporting modifications, conservative driving habits and a more thorough fuel burn, fuel economy increases are to be expected.
Is there a specific o-ring kit to buy?

Answer
All that is recommended is the Ford Turbo Bolt/O-ring Kit - XDP Part Number: FO3C3Z-9T514-AG.
