TiAL Sport GT45 1.45 A/R V-Band Clamp Stainless Steel Turbine Housing

This stainless steel turbine housing from TiAL Sport is built for the GT45 turbocharger, featuring a 1.45 A/R ratio and a V-band clamp connection. The 1.45 A/R (Area/Radius) ratio is a key spec that influences how the turbocharger spools and the powerband it produces. A larger A/R like this one generally helps the turbocharger breathe better at higher RPMs, making it suitable for applications where top-end power is a priority.

Constructed from durable stainless steel, this housing is designed to withstand the high temperatures and pressures associated with forced induction systems. The V-band clamp connection offers a secure and leak-free seal, simplifying installation and maintenance compared to traditional bolt-on flanges. This makes it a solid choice for custom turbo builds or when replacing an existing housing on a GT45 turbo. It's important to note that this part is not CARB approved and cannot be shipped to California.
