What does the A/R ratio mean for this turbine housing?

The A/R ratio, or Area/Radius, affects how the turbocharger performs. A 0.92 A/R generally allows the turbo to flow more exhaust gas at higher engine speeds, which can help achieve higher peak horsepower. It typically results in slightly slower initial spool compared to a smaller A/R.

What are the benefits of V-band connections?

V-band connections use a clamp to secure two flanged pieces together, creating a strong seal. They are often preferred for their ease of installation and removal, and they can provide a more consistent and leak-free seal compared to traditional bolted flanges, especially under high vibration and temperature conditions.

Is this turbine housing compatible with all Garrett G25 turbos?

This housing is specifically designed for the Garrett G25 series turbochargers. While it's part of the G25 line, it's always best to confirm the exact turbocharger model number you have or are planning to use to ensure full compatibility with this specific turbine housing.

Product Details

This is the Garrett G25 turbine housing, specifically the V-Band / V-Band 0.92 A/R model in stainless steel. It's a key component for building or upgrading a forced induction system, designed to work with Garrett's G25 turbocharger line. The turbine housing is where the hot exhaust gases from your engine enter and spin the turbocharger's turbine wheel, which in turn drives the compressor wheel to force more air into your engine. This particular housing features a 0.92 A/R (Area/Radius) ratio, which influences the turbo's spool characteristics and top-end power potential. A larger A/R like this one generally helps the turbo breathe better at higher RPMs, potentially leading to more peak horsepower, while a smaller A/R would typically improve low-end response.

Constructed from stainless steel, this housing is built to withstand the high temperatures and corrosive nature of exhaust gases. The V-band connections on both the inlet and outlet offer a secure and leak-free seal, and they also make installation and removal simpler compared to traditional flanged connections, especially in tight engine bays. This setup is often chosen by builders looking for a robust and reliable housing that can handle demanding conditions and help achieve specific performance goals. It's important to note that this part is not CARB approved and cannot be shipped to California.
