Housing, Turbine, TiAL P/N 008559, V-band inlet/outlet, for G SERIES G50 TURBO, 1.45 A/R

This TiAL stainless turbine housing is purpose-built for the Garrett G-Series G50 turbocharger, giving serious builders a precision-matched V-band housing solution engineered specifically around the G50’s turbine wheel geometry. It’s the right call for anyone running a G-Series G50 GTX50 setup who needs a housing that pairs correctly with TiAL’s V-band ecosystem while respecting the G50’s larger turbine bore. Choose this housing when you want a proven TiAL fitment path without guessing on flange compatibility.

Specifications

• Housing Type: Turbine Housing
• Material: Stainless
• A/R Ratio: 1.45
• Inlet/Outlet Design: V-band Inlet/Outlet
• Application: G SERIES G50 TURBO
• Garrett P/N: TiAL P/N 008559

Performance & Application

This housing is designed specifically as a new offering for the G-Series G50 platform. It shares the same inlet and outlet manifold and downpipe flanges and clamps used on TiAL housings for the GT/GTX42 and GT/GTX45 Series, simplifying parts sourcing for builders already familiar with that flange family. However, the G50’s turbine wheel bore is larger, so the standard centering ring on the downpipe flange will not fit even though the outer diameter matches. This makes it critical to source the correct larger-bore flange to ensure proper centering and sealing on the downpipe side.

Compatibility & Fitment

• Garrett G-Series G50 Turbo
• G-Series G50 GTX50 housing configuration
• Shares inlet/outlet flanges and clamps with TiAL GT/GTX42 Series housings
• Shares inlet/outlet flanges and clamps with TiAL GT/GTX45 Series housings

Frequently Asked Questions

What is the A/R ratio of this turbine housing?

This TiAL turbine housing for the G-Series G50 has a 1.45 A/R ratio.

Does this housing use the same flanges as other TiAL housings?

Yes, the TiAL G-Series G50 stainless turbine housing uses the same inlet and outlet manifold and downpipe flanges and clamps as the TiAL housings for the GT/GTX42 and GT/GTX45 Series.

Can I use the standard downpipe centering ring with this housing?

No, the centering ring on the downpipe flange does not fit because the G50 turbine wheel bore is too large, although the outer diameter fits the same. You must order the flange product code with the larger bore and centering ring designed to fit the G-Series G50 GTX50 housing properly.

What inlet and outlet flanges and clamps are required for this housing?

The V-Band Inlet Flange for the turbo manifold uses product code ATP-FLS-095 with clamp product code CLC-CLA-027, and the V-Band Outlet Flange for the downpipe uses product code ATP-FLS-446 with clamp product code CLC-CLA-028.

For G-Series G50 GTX50 builds demanding correct, verified TiAL V-band fitment, this housing delivers the precision and compatibility serious builders require — provided the correct larger-bore ATP-FLS-446 downpipe flange is used to match the G50’s turbine bore.
