2003 6.0L Powerstroke GT3788VA Stage 1 Turbo Kit (777469-5002S)

The Garrett 777469-5002S GT3788VA is a Stage 1 performance turbocharger upgrade built specifically for the early production 2003 Ford 6.0L Powerstroke. Designed as a direct bolt-on replacement, this turbo is engineered to replace the factory Garrett GT3782VA while delivering substantial gains in both horsepower and torque. Featuring a larger compressor wheel and an optimized variable geometry turbine (VGT) design, the GT3788VA improves airflow and efficiency across the powerband, all while maintaining excellent low-end response. This makes it an ideal upgrade for mild to moderate performance builds, offering reliable power gains without sacrificing drivability.
