TiAL Sport G-45 1.45 A/R V-Band Clamp Stainless Steel Turbine Housing

TiAL Sport is well-known for making robust turbocharger components, and this G-45 turbine housing is a prime example of their work. This particular housing features a 1.45 A/R ratio, which is designed to help your turbocharger spool up quickly while still allowing it to breathe efficiently at higher RPMs. The V-band clamp inlet makes for a secure and easy-to-install connection to your turbo's turbine wheel, and the entire housing is constructed from stainless steel for long-term durability and resistance to heat.

The 1.45 A/R (Area/Radius) ratio is a key spec here. A higher A/R like this one generally means the housing is larger, which helps to reduce exhaust backpressure and allows the turbo to make more power at higher engine speeds. It's a balance, though; too large an A/R can sometimes make the turbo feel sluggish down low. This specific ratio is often chosen for builds where maximizing top-end power is the goal, and it pairs well with many common turbocharger sizes used in performance applications. The stainless steel construction means you won't have to worry about rust or corrosion, even in harsh underhood environments.

This turbine housing uses a V-band clamp connection, which is a popular choice for its ease of installation and the strong, leak-free seal it creates. It’s a straightforward component to install if you're working on a turbo setup. Just remember that this part is not CARB approved and cannot be shipped to California.
