Garret's New Expanded G-XRace Lineup - GXR45-76, GXR45-80, and GXR45-82

Garrett has expanded the G-XRace lineup with three new GXR45 turbos — the GXR45-76, GXR45-80, and GXR45-82. These models were built in direct response to racer demand for more flow, more boost capability, and higher peak power in a proven motorsport-sized package.
📈 All three new sizes use Garrett’s XBoost Technology, delivering up to +29% more compressor flow compared to similar G-Series turbos. That increased flow translates into cooler, denser air and higher efficiency at big power levels.
HORSEPOWER RATING:
● GXR45-76: Rated up to 1650 HP
● GXR45-80: Rated up to 1750 HP
● GXR45-82: Rated up to 1800 HP


The new G-XRace GXR45 76, 80, 82 has been tested by Dave "Duffy" Duffield's (@duffy_davee) ethanol powered 3.2L 2JZ. The purpose-built race machine serves as a real-world validation platform for Garrett Motion's turbochargers providing real dyno results and repeat 7-second runs, including a 7.345 @ 187.7 mph pass that earned #1 Qualifier and Limited Street Champion at WCF 2025. He tested each turbo on his setup, and in the testing, we saw the following: (See Dyno graphs in slides)
