Garrett GT47 Turbine Housing Kit O/V 1.08 A/R

If you're building a high-performance engine that needs serious airflow, a larger turbocharger is often the key. This Garrett GT47 turbine housing kit is designed to help you get the most out of your turbo setup, especially when you're aiming for big power numbers. The 1.08 A/R ratio is chosen for applications where maximizing top-end power and airflow is the priority, making it suitable for drag racing or other high-RPM performance builds.

This housing is constructed from durable cast iron, a material chosen for its ability to withstand the extreme temperatures and pressures found in forced induction systems. The open-sided (O/V) design offers some flexibility in exhaust manifold fitment compared to a divided housing, which can be beneficial in custom turbo installations. Garrett is a well-known name in the turbocharger world, and this housing is built to their standards for reliability and performance. It's important to note that this part is not CARB approved and cannot be shipped to California.

When selecting a turbine housing, the A/R ratio plays a crucial role in how the turbo spools and performs at different engine speeds. A 1.08 A/R like this one will generally lead to later boost onset but will allow the turbo to breathe more freely at higher RPMs, supporting higher horsepower targets. Make sure this housing is compatible with your specific Garrett GT47 series turbocharger model and your exhaust manifold setup before purchasing.
