Turbine Housings for Supercars and Performance Cars

The turbine housing is the hot side casing that collects exhaust gas from the manifold and accelerates it onto the turbine wheel. Its internal volume relative to the radius, expressed as the A/R ratio, is what decides how quickly the turbo spools and how freely it breathes once it is up. A smaller housing gets the turbo moving early and gives strong response at the cost of restriction at the top. A larger one frees the engine higher up but asks you to wait for it. Housings also take the worst of the heat in the whole system, so cracking and warping are common on hard used cars. Supercar Store supplies turbine housings for supercars and performance cars, with delivery across Dubai and the UAE, to India, and worldwide.

What This Collection Covers

• Replacement turbine housings: factory specification castings to replace cracked, warped or eroded originals.
• Alternative A/R housings: the same frame in different ratios so you can tune spool against top end flow.
• Twin scroll housings: divided volutes that keep exhaust pulses separated for cleaner, earlier spool.
• Open and internally gated housings: castings with or without an integral wastegate port and flapper.
• Stainless and cast iron options: different materials for heat resistance, weight and crack tolerance.
• V band and flanged outlets: different discharge configurations to suit the downpipe you are running.
• Compressor housings: cold side castings and covers where a matching change is needed.
• Clamps, gaskets and hardware: V band clamps, flange gaskets, studs and lock plates for the install.

Why It Matters

Housing choice changes the personality of a turbo without touching the cartridge inside it. Move down an A/R step and the car feels sharper and more eager out of slow corners. Move up and it breathes better where it counts on a long straight. That single decision often does more for how a car feels than a larger turbo would. Replacement matters just as much, because a cracked housing leaks exhaust gas straight past the turbine, which costs boost, cooks nearby components and gets worse quickly. Twin scroll designs add another layer by keeping cylinder pulses from interfering with each other, which is why they show up on so many factory performance engines.

How to Choose the Right Turbine Housing

Start with the turbo frame, since housings are specific to it. Then choose the A/R by use. Road and street driving usually reward the smaller ratio for response in traffic and on part throttle. Track use with sustained high revs generally favours a larger ratio and a freer top end. Confirm whether you need an internally gated or open housing, because that decides how boost is controlled, and check the outlet configuration matches your downpipe so you are not fabricating on the day of the fit. Material choice is worth thinking about if the car sees repeated heat cycling. Fitment on supercars is car specific, so tell us the car, the year, the variant and the turbo part number.

Frequently Asked Questions

Which housing suits my turbo and car?
Housings are frame specific. Send us the turbo part number plus the car make, model, year, variant and how the car is used, and we will recommend the correct casting and A/R.

Do you ship housings to India and elsewhere?
Yes. We deliver across Dubai and the UAE, to India, and worldwide, with tracked shipping on every order.

Are housings in ready stock?
Some are. Specific ratios and twin scroll castings are commonly sourced to order and we confirm the lead time before you pay.

Are the castings genuine?
Yes. We supply genuine housings from established manufacturers, cast and machined to their own specification.

The A/R I want is not listed. Can you get it?
Very often, yes. Send us an inquiry with the turbo frame and the ratio you want and we will check availability.

If the housing or ratio you need is missing from this page, tell us. We can source almost any turbine housing or hot side part for your car. WhatsApp us on +971 50 308 5760 or send us an inquiry with the part and the car it is for, and we will come back with a price and a lead time.
