The G Series from Garrett represents the latest in both turbine and compressor technology in the mid-frame market. The GT57 1950 88mm delivers an impressive 195+#/Min of airflow, making it capable of 1900+ HP in a single turbo configuration. The proven Garrett GEN II GTX compressor wheel is paired with an all new 118mm G-Series turbine wheel that delivers 28% more turbine flow than the previous GTX/GT55 platform. The bearing housing is an all new, manufactured from lightweight aluminum for weight savings and features Garrett's proven 16mm dual ceramic ball bearing cartridge for un-matched durability. The new G57 is a direct fit for the previous GTX GEN II unit, meaning you can drop it in and go racing without any down time for fabrication. Turbocharger is available with your choice of Garrett's stainless steel v-band turbine housing in 1.09, 1.25 or 1.41 A/R. Need help deciding which is right for you?
