The Garrett G45-1600 is an 80mm super core assembly rated for 750 to 1600 horsepower on 2.0L to 8.0L engines. It pairs an 80mm 54-trim billet compressor wheel that flows up to 16 percent more than the GTX4508R with an Inconel 89mm G Series turbine wheel, carried on a ceramic dual ball-bearing cartridge with steel cages. This standard-rotation super core ships with the compressor housing, lightweight aluminum backplate, machined speed sensor and pressure ports, and water fittings; the turbine housing is sold separately.
