Product Description

The Garrett 740902-0008 Turbine Housing Kit is engineered for high-performance turbocharger applications using the GT30R and GTX30 series. Featuring a cast Ni-Resist construction for excellent heat resistance and durability, this turbine housing offers a T3-standard inlet flange and a 3" V-Band outlet for flexible exhaust routing and high exhaust flow capacity. The 0.82 A/R ratio helps balance quick turbine response with strong top-end power characteristics, making it well-suited for custom turbo builds and high-boost applications.

This turbine housing is a universal component - it does not bolt directly to any specific year/make/model vehicle on its own but is designed as part of turbine assemblies in aftermarket turbocharger systems. Typically paired with compatible Garrett GT30R/GTX30 super cores and custom exhaust manifolds, it allows builders and tuners to optimize their turbo setups for balance between spool-up and peak performance. Because this kit includes only the turbine housing, the turbo core (CHRA), external wastegate hardware, and other mounting hardware must be sourced separately to complete a working turbocharger assembly.
