Garrett G-Series G30 Reverse Rotation Turbine Housing Kit – 0.61 A/R V-Band

Description

Garrett G-Series G30 Reverse Rotation Turbine Housing Kit – 0.61 A/R V-Band (740902-0096)

Elevate your custom turbocharger build with the genuine Garrett G-Series G30 Reverse Rotation Turbine Housing (Part Number: 740902-0096). Engineered specifically for the latest generation of G30 supercores, this housing is designed to provide rapid boost response and maximum heat efficiency for high-performance applications.

This 0.61 A/R housing is the smallest ratio in the G30 range, making it the ideal choice for tuners prioritising fast spool-up and low-end torque. Crafted from high-grade stainless steel, it is rated to withstand extreme exhaust temperatures up to 1050°C, ensuring reliability on both the track and the street.

Key Performance Features:

• Reverse Rotation Design: Specifically engineered for reverse rotation G30 supercores (ideal for twin-turbo setups or specific engine bay packaging requirements).

• Optimised Response: The 0.61 A/R ratio provides the quickest transient response in the G30 family, perfect for 2.0L to 3.5L engines.

• V-Band Connectivity: Features V-Band inlet and outlet flanges for a secure, leak-free seal and 360-degree clockability, simplifying custom downpipe and manifold fabrication.

• Stainless Steel Construction: Superior durability and heat resistance compared to traditional cast iron housings.

• Free Float Design: Non-wastegated (Free Float) configuration for use with external wastegates.
