Product Description
The Garrett 757707-0025 G45 Turbine Housing Kit is engineered for high-performance turbocharger setups requiring maximum exhaust flow efficiency and durability. Designed specifically for Garrett G-Series G45 turbochargers, this turbine housing features a divided T4 inlet flange and V-band outlet, making it ideal for performance, racing, and high-horsepower diesel or gas applications.
With a 1.28 A/R ratio, this housing is optimized for top-end power while maintaining efficient exhaust velocity. The divided (twin-scroll) T4 design helps improve spool characteristics by separating exhaust pulses, resulting in increased turbo efficiency and reduced lag when paired with the proper manifold setup.
Constructed from high-quality, heat-resistant materials, this turbine housing is built to withstand extreme temperatures and harsh operating conditions common in competitive and heavy-duty environments.

FAQ
What does a 1.28 A/R turbine housing do?
A 1.28 A/R housing is designed for maximum top-end power, allowing greater exhaust flow at high RPM, ideal for high horsepower builds.
What is a divided T4 flange?
A divided (twin-scroll) T4 flange separates exhaust pulses from paired cylinders, improving turbo efficiency and spool response when used with a compatible manifold.
Is this compatible with all G-Series turbos?
No, this housing is specifically designed for Garrett G45 turbochargers.
What is the benefit of a V-band outlet?
V-band connections provide a secure, leak-free seal and make installation and removal easier compared to traditional flange setups.
