Product Description

The Garrett 757707-0034 G40 Turbine Housing Kit is a high-performance exhaust housing designed for use with Garrett G40 series turbocharger cores such as the G40-900 and G40-1150. With a **1.06 A/R** ratio, it offers a balanced combination of turbine spool response and strong mid-range to top-end airflow, making it suitable for custom and high-boost forced-induction systems. The T4 divided inlet flange enhances exhaust pulse separation, helping optimize turbine dynamics in TwinScroll configurations.

This universal turbine housing features robust construction capable of withstanding the high temperatures and pressures found in performance turbo systems. Its V-Band inlet and outlet connections provide secure, reliable exhaust routing while supporting external wastegate setups for precise boost control. Because it's a **universal component** rather than a vehicle-specific drop-in, it must be paired with a compatible turbo core (CHRA), appropriate mounting hardware, and necessary plumbing to complete a functional turbocharger assembly tailored to your engine and performance goals.
