GARRETT 757707-0026 G45 TURBINE HSG KIT DIV T4 / V-BAND 1.44 A/R - STANDARD ROTATION

Product Description

The Garrett 757707-0026 G45 Turbine Housing Kit is engineered for high-performance turbocharger builds requiring maximum exhaust flow and efficiency. Designed specifically for Garrett G-Series G45 turbochargers, this turbine housing features a divided T4 inlet and V-band outlet, optimizing exhaust energy delivery and improving spool characteristics.

With a 1.44 A/R ratio, this housing is ideal for high-horsepower applications where top-end performance and sustained boost are critical. The divided (twin-scroll) T4 flange design enhances exhaust pulse separation, increasing turbine efficiency and reducing lag when paired with the correct manifold setup.

Built from high-quality, heat-resistant materials, this turbine housing is capable of withstanding extreme exhaust temperatures commonly found in racing, competition, and high-output diesel or gasoline applications.

This is the perfect upgrade or replacement for performance enthusiasts building custom turbo setups or pushing their G45 turbocharger to its limits.

FAQ

What does a 1.44 A/R mean?
A 1.44 A/R turbine housing is designed for high airflow and top-end power, making it ideal for high horsepower builds but with slightly slower spool compared to smaller A/R options.

What is a divided T4 flange?
A divided (twin-scroll) T4 flange separates exhaust pulses from the engine, improving turbo efficiency, reducing lag, and increasing overall performance when paired with the correct manifold.

Is this compatible with all G45 turbos?
Yes, this housing is specifically designed for Garrett G45 series turbochargers using standard rotation.

Is fabrication required?
In most custom applications, yes. Proper fitment depends on your exhaust manifold and overall turbo system setup.
