TiAL Sport GT28 .62 A/R IWG Stainless Steel Turbine Housing

If you're building a custom turbo setup for your performance vehicle and need a specific turbine housing to match your engine's needs, this TiAL Sport GT28 housing is a solid choice. It's designed to work with GT28 series turbos and features a .62 A/R ratio, which is a good balance for many applications looking for improved spool without sacrificing too much top-end power. The internal wastegate (IWG) port is already integrated, simplifying your plumbing compared to external wastegate setups.

This housing is constructed from durable stainless steel, chosen for its ability to withstand the high temperatures and corrosive exhaust gases found in forced induction systems. The .62 A/R (Area/Radius) measurement is a key spec that dictates how quickly exhaust gas flows into the turbine wheel. A smaller A/R like this one generally leads to quicker turbo spool-up, meaning your engine reaches boost pressure sooner. This can make a noticeable difference in throttle response, especially in the lower RPM range. TiAL Sport is well-known in the performance turbo community for making well-built components, and this housing is no exception. It's designed to fit right with compatible GT28 turbos, making installation as straightforward as possible for a custom turbo component.

When planning your turbo build, remember that the turbine housing is just one piece of the puzzle. You'll need to ensure it's properly matched with your compressor housing, exhaust manifold, and fuel system to achieve your desired performance goals. This housing is not CARB approved and cannot be shipped to California. Always refer to your specific turbocharger's documentation and consult with a professional if you have questions about compatibility or installation.
