What does the 0.92 A/R ratio mean for performance?

The A/R ratio measures the area of the turbine housing's volute divided by its radius. A 0.92 A/R generally provides a good balance between turbocharger spool speed and high-RPM boost capability, offering strong performance across a wider range of engine speeds.

What are the advantages of V-band connections?

V-band connections use a clamp and flange system to create a seal. They are known for being robust, easy to install and remove, and providing a reliable, leak-free connection that can withstand high temperatures and pressures.

Can this turbine housing be used on any turbocharger?

This turbine housing kit is specifically designed for Garrett G25 turbochargers. While V-band connections are common, the internal dimensions and mounting flange are specific to the G25 series. Always confirm compatibility with your turbocharger model.

About this part

Product Details

Garrett is well-known for their high-performance turbochargers and components, and this G25 Turbine Housing Kit continues that legacy. This specific kit is designed for reverse rotation applications, featuring a 0.92 A/R ratio and V-band connections on both the inlet and outlet. The A/R ratio is a critical measurement that affects how quickly the turbocharger spools up and how much boost it can produce at higher RPMs. A 0.92 A/R generally offers a good balance, allowing for strong top-end power while still providing reasonable response.

This housing is constructed from durable materials to withstand the extreme temperatures and pressures found in forced induction systems. The V-band connections offer a secure and leak-free seal, simplifying installation and maintenance compared to traditional flanged setups. This kit is intended for builders and tuners looking to customize or upgrade their forced induction system with a reliable Garrett component. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.

When building a custom turbo system, selecting the right turbine housing is crucial for achieving your desired performance goals. This Garrett G25 housing, with its specific A/R and V-band configuration, is a solid option for those aiming for a well-rounded powerband. Always ensure compatibility with your specific turbocharger model and supporting components before installation.
