TURBINE HOUSING Garrett GTX50 (or GT50), T6 Undivided Inlet Flange

The Garrett GTX50/GT50 T6 undivided inlet turbine housing is built for tuners and engine builders who demand precise control over spool characteristics and top-end exhaust flow on large-frame Garrett turbo builds. Offered in three distinct A/R ratios, this housing lets you dial in your GT50 or GTX50 turbocharger to match your specific power goals and engine displacement. It’s the ideal choice for high-horsepower builds where matching turbine housing geometry to the application is critical to performance.

Performance & Application

This turbine housing is designed specifically for the Garrett GT50 and GTX50 turbocharger platform, giving builders a way to tailor exhaust housing sizing to their target power band. The .96 A/R option favors quicker spool response, while the 1.23 A/R option is suited to builds prioritizing top-end exhaust flow, with the 1.08 A/R serving as a middle ground between the two. The T6 undivided inlet flange design and 5″ V-band discharge make this housing well suited to high-output, large-frame turbo installations where efficient exhaust gas management is essential.

Compatibility & Fitment

• Garrett GT50 turbochargers
• Garrett GTX50 turbochargers
