The SWAG Performance Stage 1.5 Turbo Upgrade Kit is designed for Powerstroke owners who want more than a simple compressor wheel upgrade without the expense of purchasing a complete aftermarket turbocharger.
By combining our proven 66/88 billet compressor upgrade, 4-inch anti-surge compressor housing, premium turbo rebuild kit, and 33 PSI billet wastegate actuator, this package completely refreshes your factory Garrett GTP38 while delivering substantial improvements in airflow, boost control, reliability, and overall performance.
Whether your goal is towing, daily driving, or supporting future engine modifications, the Stage 1.5 package provides everything needed to rebuild and modernize your factory turbocharger in one complete kit.
Why Stage 1.5?
The SWAG Performance Stage 1.5 Turbo Upgrade bridges the gap between a basic compressor housing upgrade and the cost of a complete replacement turbocharger.
Unlike entry-level upgrade kits, the Stage 1.5 package not only increases airflow but also replaces the turbocharger's primary wear components and upgrades boost control. This results in a turbocharger that performs better, responds quicker, and is ready to support additional horsepower for years to come.

This comprehensive package is ideal for trucks with higher mileage, worn turbochargers, or owners looking to maximize performance and reliability during a single installation.
