Turbine Housing, Garrett GT55 / GTX55 (T6 Inlet & V-Band Outlet)

Built for the highest-output GT55 and GTX55 platform builds, this Garrett turbine housing pairs a T6 undivided inlet with a large-bore V-band outlet to handle serious exhaust volume without compromise. It’s engineered for tuners and engine builders who need to dial in spool characteristics against top-end power for extreme-displacement or high-boost applications. Multiple A/R offerings let you match housing sizing precisely to your power goals and turbo configuration.

Specifications

• Turbine Inlet Flange: T6 Undivided
• Outlet: 5″ V-Band
• Available A/R Ratios: 1.00, 1.12, 1.24, 1.40, 1.78 A/R
• Compatible Turbo Series: GT55 / GTX55

Performance & Application

This turbine housing is designed to work exclusively with GT55 series and GTX55 series turbochargers, making it a core building block for extreme-horsepower forced induction setups. The range of A/R options allows builders to tune spool-up response versus peak power delivery to suit specific engine displacement and boost targets. Smaller A/R selections favor quicker transient response, while larger A/R selections are suited to maximizing top-end flow on high-displacement, high-power builds. This housing is intended for enthusiasts and engine builders assembling or upgrading a GT55/GTX55 turbocharger for serious performance applications.
