Garrett PowerMax 6.0L Power Stroke Turbo Upgrade suitable for Ford F-250, F-350 and Excursion 2004-2007
Garrett PowerMax GT3788VA turbocharger suitable for the 6.0L Power Stroke diesel in the Ford F-250, F-350 and Excursion. Garrett’s patented Advanced Variable Nozzle Turbine (AVNT) design uses nine movable vanes, which lift turbine efficiency and improve engine response from idle through to peak torque. The compressor wheel is larger than stock, which raises the maximum power range while keeping turbo speeds down for the same output. It supports up to 560HP.

❓ FAQs:
Q: Is this a direct bolt-on?
A: Yes. It is outline interchangeable with the factory turbo, so it fits in place of the original with no fabrication.
Q: Do I need a tune?
A: Garrett’s power figure is the turbo’s capability from flow testing, and real results depend on your vehicle’s modifications and tune. We recommend dyno tuning for best results.
Q: Is it suitable for a 2003 6.0L?
A: No. The 2003 Ford F-Series and Excursion 6.0L use a different Garrett part number, 777469-5002S.
