Description
The Garrett G38/GXR38 Turbine Housing Kit O/V V-Band / V-Band 0.85 A/R (Part Number 757707-0037) is designed for high-performance turbocharger applications requiring efficient exhaust flow, fast response characteristics, and reliable operation under demanding conditions. The Garrett G38 turbocharger platform was developed for performance engines ranging from 2.0L to 5.5L, making it suitable for a wide range of racing, drag, and high-output engine builds.
The G38 turbine section utilizes an advanced Inconel turbine wheel featuring a 74 mm inducer and 66 mm exducer, paired with durable stainless steel turbine housings available in V-Band and T4 divided configurations. Multiple A/R options allow the G38 platform to be optimized for different power goals, boost response requirements, and engine setups.
The G38 compressor lineup includes the G-XRace GXR38-64 with a 64 mm compressor and hose or V-Band compressor outlet configurations, as well as the G-Series II G38-1000 featuring a 62 mm compressor with a hose compressor outlet. These compressor options provide increased pressure ratio capability, improved airflow efficiency, reduced weight, and advanced turbocharger monitoring compatibility.
The 0.85 A/R turbine housing configuration provides an excellent balance between turbo response and high-flow performance, making it ideal for applications where quick spool characteristics and strong top-end power are required.
