Garrett G57 Turbine Housing Kit 1.09 A/R O/V V-Band In/Out

This Garrett G57 turbine housing features a 1.09 A/R ratio and V-band connections for both inlet and outlet. The A/R ratio, which is a measure of the turbine housing's size relative to its volute area, directly impacts the turbocharger's spool characteristics and top-end power potential. A 1.09 A/R is generally suited for applications looking to achieve strong mid-range power and a broader powerband, balancing quick response with the ability to support higher engine speeds.

Constructed from durable cast iron, this housing is built to withstand the high temperatures and pressures associated with forced induction systems. The V-band inlet and outlet design offers a secure and leak-free connection, simplifying installation and maintenance compared to traditional flanged setups. This housing is specifically designed for the Garrett G57 turbocharger, ensuring proper fitment and optimal performance when paired with its intended compressor housing and rotating assembly. It's an open-wastegate (O/V) design, meaning it's intended for use with an external wastegate setup, giving you precise control over boost levels.

This kit includes the turbine housing itself. Remember that this part is not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure this housing is installed by a qualified technician familiar with turbocharger systems and that all associated components, such as the wastegate and exhaust manifold, are properly matched and functioning.
