The G-Series G57-2750 102mm Turbocharger Is Here to Deliver Big Power

Capable of flowing up to 2750HP worth of air, the 102mm Garrett G57 turbocharger requires a LOT of fuel, but you'll get a lot of power too, so the trade-off is worth it. Designed specifically for massive displacement, high boost, and enormous power builds, this turbo will deliver everything you need and more. A part of the G57 lineup of the G-Series from Garrett, this turbo finds itself on the top end of the spectrum with only the G57-3000 putting out more power. If you don't quite need this much power, then we suggest checking out the G57-2550, G57-2350, or G57-2000

This turbo features a new high-flowing Inconel turbine wheel and lightweight one-piece aluminum CHRA are the two major features that differentiate the G57 from its GTX predecessor.

Turbine Stage

The newly engineered turbine wheel with optimized G Series aerodynamics increases flow by up to 28% (Compared to GTX Gen II, see graph below). The large 90 trim turbine stage measures 118mm at the inducer and 112mm at the exducer. G57 is offered with three stainless steel V-band turbine housings in 1.09 A/R, 1.25 A/R, and 1.41 A/R. Center Housing: One-piece aluminum center housing reduces supercore weight.

The center housing is air-cooled, features a 16mm dual ceramic ball bearing for premium rotor dynamics, and retains the oil inlet and outlet specifications from previous GTX designs. Compressor Stage: Garrett G57 compressor stages are offered in 88mm, 94mm, 98mm, 102mm, and 106mm inducer sizes each with its own horsepower ratings indicated in the model name.
