Housing, Turbine, TiAL P/N 006393, V-band inlet/outlet, GTX50R, 1.17 A/R

This TiAL stainless turbine housing is purpose-built for the Garrett GTX50R turbocharger, giving serious builders a dedicated V-band solution engineered for high-output applications. It’s the right choice for anyone running a GTX50R who wants a housing designed specifically for the platform rather than a generic fit. PT Turbo offers this as a new dedicated offering for the GTX50 series.

Specifications

• A/R Ratio: 1.17
• Inlet Type: V-band
• Outlet Type: V-band
• Material: Stainless (TiAL)
• Application: GTX50R
• Garrett P/N: 006393

Performance & Application

This housing is engineered specifically for the GTX50 series, giving GTX50R builds a purpose-matched turbine housing rather than a repurposed unit from another platform. It shares inlet and outlet manifold and downpipe flange compatibility with the TiAL housings used on the GT/GTX42 and GT/GTX45 series, simplifying sourcing for shops already running TiAL V-band hardware. Because the GTX50 turbine wheel bore is larger, the downpipe flange centering ring from the 42/45 series will not fit, so the correct larger-bore flange must be used for proper fitment. This makes it the correct housing choice specifically for GTX50R applications rather than a universal fit across the GT/GTX42-50 range.

Compatibility & Fitment

• Designed for Garrett GTX50R turbochargers
• Shares inlet and outlet (manifold and downpipe) flanges and clamps with TiAL housings used on GT/GTX42 and GT/GTX45 series
• Downpipe flange centering ring from GT/GTX42-45 does not fit due to the larger GTX50 turbine wheel bore, though the outer diameter fits the same
• Requires flange product code ATP-FLS-446 (larger bore with centering ring) for proper fitment to GT/GTX 47/50 series housing

Frequently Asked Questions

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

This TiAL turbine housing for the GTX50R has a 1.17 A/R ratio.

Does this housing use the same flanges as the GT/GTX42 and GT/GTX45 series?

Yes, the TiAL GTX50R 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.

Will the standard GT/GTX42-45 downpipe flange centering ring fit this housing?

No, the centering ring on the downpipe flange does not fit because the GTX50 turbine wheel bore is too large, although the outer diameter fits the same. You must order flange product code ATP-FLS-446, which has the larger bore and centering ring to fit the GT/GTX 47/50 series housing properly.

What inlet and outlet configuration does this housing use?

This housing features a V-band inlet and V-band outlet configuration.

For GTX50R builds demanding precise, purpose-matched hardware, this TiAL V-band turbine housing delivers the correct fitment and flange compatibility to get your setup right the first time.
