Built for tuners who demand precise control over spool and top-end flow, this T3 inlet turbine housing gives GT28RS, GT2876R, GT2871R, and GTX28R series turbo owners a proven path to dial in turbine sizing for their specific power goals. Whether you’re chasing quicker spool for street response or maximizing flow for higher horsepower builds, this housing lets you match turbine characteristics to your application. It’s the housing serious Garrett GT28/GTX28 platform owners turn to when stock configurations don’t fit the build.
Specifications
- Inlet: T3
- Outlet: T31 4-bolt, 2.5″
- Turbine A/R Options: .63 A/R or .82 A/R
Performance & Application
This turbine housing fits the turbine wheel found on GT28RS, GT2876R (also known as GT25/40R), GT2871R, and Gen1/Gen2 GTX28R series turbos. The .63 A/R option is suited to builds prioritizing faster spool and quicker throttle response, while the .82 A/R option is built for applications targeting higher top-end flow. This flexibility makes it a strong fit for enthusiasts upgrading or customizing their GT28/GTX28 platform turbo for a specific power and response balance.
