Turbosmart Turbocharger Housing

Turbosmart Turbocharger Housings: Precision-Engineered for Maximum Flow

When it comes to turbine housings, few names carry the engineering credibility of Turbosmart. Founded in Australia in 1997 and now a globally recognized force in forced induction, Turbosmart has applied the same obsessive attention to materials science and aerodynamics to their turbocharger housings as they have to their legendary wastegates and blow-off valves. The result is a lineup of turbine housings that is purpose-built for both motorsport competitors and serious performance enthusiasts.

What Sets Turbosmart Turbine Housings Apart

The defining feature of every Turbosmart turbine housing is the material choice: 310s stainless steel investment castings. This grade of stainless is selected specifically for its ability to withstand extreme exhaust gas temperatures without warping or cracking — a critical consideration in high-boost applications where EGTs routinely push the limits of lesser materials. Investment casting also allows Turbosmart to achieve tighter dimensional tolerances than sand casting, which directly translates to more consistent flow characteristics from unit to unit.

Beyond raw material quality, each housing is developed using Computational Fluid Dynamics (CFD) simulation. This means the internal volute geometry — including the all-important tongue location and scroll cross-section — has been optimized mathematically for each specific A/R ratio before a single part is ever cast. The goal is to ensure that the housing feeds exhaust energy to the turbine wheel with minimal turbulence and pressure drop, maximizing both spool speed and peak flow.

TS-1 and TS-2 Series Compatibility

Turbosmart's turbine housings are engineered as genuine factory-specification components for their TS-1 (oil-cooled) and TS-2 (oil- and water-cooled) turbocharger families. Available in multiple flange configurations — including T3, T4, and V-Band inlet options — and across a range of A/R specifications, these housings allow builders to fine-tune spool characteristics and top-end flow for their specific power target and RPM range. Whether the application calls for aggressive low-end response on a circuit car or maximum top-end flow on a drag racing build, there is a Turbosmart housing sized for the job.

Because these are genuine Turbosmart components rather than aftermarket alternatives, each housing is dimensionally identical to what leaves the factory during hand assembly of a complete unit. This means a housing swap or upgrade involves no fitment surprises — bolt patterns, V-band interfaces, and turbine exducer clearances are all held to the same specification as a brand-new turbocharger.

Rebuild, Upgrade, or Start Fresh

Turbosmart positions these housings both as service/rebuild parts for existing TS-series turbochargers and as upgrade components for builders seeking a different A/R ratio without replacing an entire turbocharger assembly. This flexibility makes them an especially valuable part of any performance build where the power target may evolve over time. Changing from a tighter A/R for better low-RPM response to a larger A/R for higher peak flow is as straightforward as swapping the housing itself.

With 27 housing variants in stock spanning multiple frame sizes, flange types, and A/R ratios, the Turbosmart turbine housing lineup covers a wide range of applications under the same proven engineering philosophy: smaller, lighter, and faster — without ever compromising thermal durability or precision fit.
