Product Description

The Garrett 740902-0088 GT40R Turbine Housing Kit is a premium exhaust housing designed for high-performance turbocharger applications using GT40R, GTX40R, and compatible cores. Featuring a 1.05 A/R ratio, this housing supports strong mid-range and top-end airflow while providing flexibility in turbocharger design and exhaust integration. Its robust cast alloy construction delivers durability in high-temperature environments common to high-boost and motorsport use.

This turbine housing is a **universal turbo component**, not a direct vehicle-specific part. It must be paired with a compatible turbocharger core (CHRA), external wastegate hardware if required, and all necessary plumbing to complete a functional custom turbo system. Its design makes it ideal for engine builders and performance tuners crafting bespoke forced-induction setups tailored to specific power goals and engine configurations.
