Garrett G38/GXR38 Turbine Housing Kit T4 Div/V-Band 1.06 A/R 757707-0044

Vehicle Fitment

• Universal - compatible with Garrett G38/GXR38 platform turbochargers on 2.0L-5.5L engine builds (auto, and select marine/industrial per the platform's broader GXR38-64 compatibility)

Fitment Notes

• Turbine housing only - requires a compatible Garrett G38/GXR38 supercore or CHRA (sold separately) for a complete turbocharger
• T4 divided inlet requires a matching T4 divided exhaust manifold or downpipe flange - not compatible with V-Band inlet manifolds
• Not CARB legal; not for sale or use in California

Features

• Stainless steel construction for durability and high-temperature resistance
• T4 divided inlet with V-Band outlet configuration

Product Description

The Garrett 757707-0044 is a stainless steel turbine housing built for the G38/GXR38 turbocharger platform, featuring a T4 divided inlet and V-Band outlet with a 1.06 A/R ratio for engines from 2.0L to 5.5L in displacement. As the largest A/R in the T4 divided housing lineup, it prioritizes maximum top-end exhaust flow for higher sustained power on larger displacement or higher-boost builds, while the divided inlet still preserves exhaust pulse energy for reasonable spool characteristics.

Its Inconel-compatible turbine section (74mm inducer, 66mm exducer) is built to withstand sustained high-temperature exhaust flow. As a standalone turbine housing, this component requires a compatible G38/GXR38 supercore or CHRA to form a complete turbocharger, and the T4 divided inlet must be paired with a matching divided exhaust manifold.
