The Garrett GTX4088R is a dual ball bearing turbocharger engineered for enthusiasts chasing serious top-end power without sacrificing the responsiveness that separates a great turbo build from an average one. Built around Garrett’s 11-Blade compressor technology, this unit is designed for high-horsepower street and race applications where flow, durability, and spool characteristics all matter equally. It’s the choice for builders who need a turbo capable of supporting big power targets while retaining the drivability that ball bearing architecture provides.

Performance & Application
The GTX4088R is built for builders targeting 850HP potential flow, making it well suited for high-output performance engines that demand strong top-end capability. Its dual ball bearing design supports quicker spool response compared to traditional journal bearing turbos, while the 11-Blade compressor wheel technology is engineered for ultra-high flow performance. The V-band inlet and outlet turbine housing, offered in multiple A/R ratios, allows builders to tailor the balance between throttle response and peak power output for their specific application. This combination makes the GTX4088R a strong fit for serious performance builds where both flow capacity and response matter.
