Garrett G25-550 turbocharger 0.72 A/R
The newest generation of Garrett turbocharger
A real evolution of the GTX turbos
Garrett now launches a new line of turbochargers that are close to the BorgWarner EFR turbochargers - the G25 series. The special features are:
- Forged and machined compressor wheel of the latest generation with up to 15% more flow (than the GTX series, Gen II series) on 60mm wheels and even 30% more flow on 67mm compressor wheels
- Highflow compressor housing with optional connection for the speed sensor
- Turbine wheel made of Mar-M (up to 1050° C resistant) with 15 to 20% more flow
- Stainless steel turbine housing resistant up to 1050° C
- Exhaust housings with V-band inlet and V-band outlet
- CHRA with V-band to be twisted individually
- Double ceramic ball bearings
- 4 water connection ports
- Double seal on the piston rings
- Right and left rotating turbochargers available.
Power range: Up to 550HP
Engine capacity: 1,4 up to 3,0l
Notice: Rotation is clockwise!
A/R Valuet: 0.70
A/R value: 0,72

The absolute novelty of the GTX Gen II turbocharger was naturally adopted in the Gen II series. The G-Turbos are also available as reverse rotating turbochargers.
GENERAL GARRETT G SERIES TURBOCHARGER DESCRIPTION
All G compressor wheels are CFD designed, forged and milled from special, high strength aluminum alloys. The new G-Series compressor wheels achieve 15% more airflow on 60mm wheels and 30% more on the 67mm wheels than the GTX Gen II compressor wheels.
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, 15-20% more exhaust gas flow was achieved with the same wheel dimensions compared to the GTX turbocharger.
The exhaust housings are cast from a special stainless steel alloy which also withstands up to 1050° C. Currently the turbine housings are only available with V-band flanges and without wastegate. In the future, all other flange patterns and internal wastegate options will also be available here.
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.
