Garrett G42 Turbine Housing Kit Div T4 / V-Band 1.28 A/R

This kit includes the Garrett G42 turbine housing, designed for high-performance forced induction setups. It features a T4 divided turbine inlet, which helps maintain exhaust gas energy and spool response by separating the exhaust pulses from each cylinder. The outlet is a V-band style, making for a secure and easy-to-service connection to your downpipe.

The housing has an A/R ratio of 1.28. This specific ratio is chosen to balance exhaust flow and backpressure for a wide range of engine sizes and power goals, typically favoring top-end power while still offering reasonable spool characteristics. Garrett is well-known for its robust construction and performance-oriented turbocharger components, and this housing is built to handle the demands of serious engine builds. The cast iron material is chosen for its durability and ability to withstand high exhaust temperatures.

When installing this housing, ensure you have the correct V-band clamp and mating flange for your downpipe. Proper sealing is crucial for performance and to prevent exhaust leaks. This component is intended for custom turbocharger applications where precise control over spool and power delivery is desired.
