All G compressor wheels are CFD designed, forged and milled from special, high strength aluminum alloys. The new G-Series compressor wheels achieve up to 30% more flow than the GTX Gen II compressor wheels.

Compressor housing:
The new aero-optimized high-flow compressor housings with integrated mounting for optional speed measuring sensors are adapted to the new G-series compressor wheels. The generation I improved recirculation systems have been adopted in the G-Series and significantly extend the operating range of the compressor by shifting the surge line.

All Garrett G CHRA’s are equipped with 4-port water cooling. So 2 connections can be selected on each side. This considerably facilitates the installation of the water pipes and hoses. And of course the G-Series comes with a double ceramic ball bearing like the Gen II. New is the double piston ring seal on both sides.

The new tubrine wheels are made of the high-performance material Mar-M. This material withstands exhaust gas temperatures up to 1050° C. Here too 75% more exhaust gas flow was achieved with the same wheel dimensions compared to the GTX turbocharger.

Turbine housing:
The exhaust housings are cast from a special stainless steel alloy which also withstands up to 1050° C.

If this turbocharger is not marked as stocked, it may still be the case that we have the individual components in stock and can assemble the turbocharger for you. Please call us or send an email to check if the turbocharger may be available from stock. You can also ask if alternatively shorter delivery times than specified are possible, as this often depends on the right time of the order.
