Performance & Application
The G25-550 delivers up to 550HP from a small frame package, making it a strong candidate for builds where compact turbo sizing and high output must coexist. Its Ultra High Flow G-Series compressor wheel is paired with an evolutionary aero G-Series turbine wheel, giving this unit the aerodynamic pedigree Garrett’s G-Series is known for. The reverse rotation configuration and V-band turbine housing make this turbo well suited for installations requiring specific orientation and clamping solutions rather than traditional flanged housings. Its Mar-M alloy turbine wheel construction supports sustained high-heat operation for demanding performance applications.
