Performance & Application
The GTX4088R is built for enthusiasts targeting high-horsepower output while retaining strong drivability characteristics. Its ultra high flow compressor wheel combined with Garrett’s 11-Blade technology is designed to maximize flow efficiency at the top end without giving up throttle response. Selectable turbine housing A/R sizing allows builders to dial in spool characteristics to match their specific power goals and driving style, from more responsive setups to housings optimized for peak flow. This turbo is suited to high-output builds where both strong mid-range pull and serious top-end capability are required.
