TiAL Sport GT35 .63 A/R Reverse Rotation Stainless Steel Turbine Housing

TiAL Sport is well-known for making high-performance turbocharger components, and this GT35 turbine housing is a prime example of their work. This housing is designed for reverse rotation setups, meaning it spins the opposite direction of a standard turbine wheel. This is often used in twin-turbo applications or specific custom builds where exhaust manifold routing or turbo placement requires it. The .63 A/R (Area/Radius) ratio is a key spec that influences how the turbo spools and breathes. A smaller A/R like this generally helps the turbocharger build boost pressure quicker at lower RPMs, making it a good choice for applications where you want improved throttle response off the line.

Constructed from stainless steel, this turbine housing offers solid resistance to the extreme heat and corrosive exhaust gases found in forced induction systems. This material choice helps ensure longevity and consistent performance even under demanding conditions. The reverse rotation design is a specific feature for builders who need to orient the turbocharger in a particular way, often to optimize plumbing or clear other engine bay components. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.

When planning your build, remember that this is just the turbine housing. You'll need to ensure you have the correct matching turbine wheel and compressor cover for your specific GT35 turbocharger assembly. Proper installation and exhaust manifold fitment are crucial for optimal performance and reliability.
