What does the 1.30 A/R ratio mean for my turbo?

The A/R ratio (Area/Radius) affects how the exhaust gas flows into the turbine. A 1.30 A/R is a larger housing that generally promotes better high-RPM power by allowing the turbine to spin more freely, but it might slightly delay boost response compared to a smaller A/R.

What material is this turbine housing made of and why does it matter?

This housing is made from stainless steel. This material is chosen for its strong resistance to corrosion and its ability to withstand the extreme heat generated by exhaust gases in a performance engine, contributing to its longevity.

What hardware is needed for installation?

You will need appropriate exhaust manifold gaskets and any necessary hardware for mounting the housing to the turbocharger's center section. It's recommended to use high-temperature rated hardware and gaskets for a reliable seal.

Product Details

This 1.30 A/R turbine housing is crafted from durable stainless steel, designed to handle the high temperatures and pressures found in performance forced induction setups. The 80mm inlet is specifically matched to the EFR series turbochargers, ensuring optimal flow and efficiency for engines pushing significant power. Choosing the right A/R ratio is crucial for tuning your turbocharger's performance curve. A higher A/R like this 1.30 generally helps improve top-end power by allowing the turbine to spool more freely at higher RPMs, making it a solid choice for builds focused on maximum horsepower.

TiAL Sport is known for well-built components that stand up to demanding use. This stainless steel housing offers good resistance to corrosion and thermal stress, which is important for longevity in a high-performance application. The precise fitment for the EFR 80mm turbo means you won't have issues with leaks or poor sealing, contributing to consistent boost control and overall engine reliability. It's a key piece for anyone looking to fine-tune their turbo system for aggressive power delivery.

When installing this turbine housing, ensure you have the appropriate gaskets and hardware for a leak-free seal. Because this part is not CARB approved, it cannot be shipped to California. Always refer to your turbocharger manufacturer's specifications and your engine tuner's recommendations to confirm this housing's suitability for your specific build.
