What does the 1.00 A/R ratio mean for my engine?

The A/R ratio (Area/Radius) of a turbine housing affects how quickly the turbocharger spools up and the amount of boost it can produce. A 1.00 A/R is generally considered a larger housing that favors top-end power and may have a slightly higher boost threshold compared to smaller A/R ratios.

What type of exhaust connection does this housing use?

This turbine housing kit uses a T6 inlet flange for connecting to the exhaust manifold or header, and a V-band clamp system for the outlet, which connects to your downpipe.

Is this turbine housing compatible with all Garrett turbochargers?

No, this specific turbine housing is designed for the Garrett G55 series turbochargers. It is crucial to verify that your turbocharger model is compatible with this housing before purchase.

Product Details

Garrett is well-known for its high-performance turbochargers and components, trusted by racers and tuners worldwide. This G55 Turbine Housing Kit is designed to be a direct replacement or upgrade for specific Garrett turbocharger applications, allowing you to fine-tune your engine's power delivery. The 1.00 A/R ratio is a key specification that influences how the turbocharger responds at different engine speeds, affecting both boost threshold and peak power potential.

This kit features a T6 inlet flange and a V-band outlet, common connection types for high-flow exhaust systems. The cast iron construction is chosen for its durability and ability to withstand the high temperatures and pressures found in the exhaust stream of a turbocharged engine. Precise casting ensures a smooth internal surface for efficient exhaust gas flow, which is critical for turbocharger spool and overall performance. This housing is intended for use with the Garrett G55 series turbochargers, and it's important to confirm compatibility with your specific turbocharger model and engine build.

When installing this turbine housing, remember that it's a critical part of your exhaust and turbo system. Proper sealing at the V-band connection and secure mounting to the turbine wheel assembly are essential for reliable operation and to prevent exhaust leaks. Due to its performance-oriented design and materials, this component is not CARB approved and cannot be shipped to California.
