The Garrett G30-900R is a G-Series turbo rated to 900hp. Garrett's G-Series uses a forged, fully machined compressor wheel and a Mar-M alloy turbine wheel rated to 1055°C, running on a dual ball bearing centre section that's both oil and water cooled. The result is quick spool, strong top-end flow and the durability Garrett is known for.

This listing is for the G30-900R supercore: the compressor housing, centre section and turbine wheel. Choose Supercore only if you already have a matching turbine housing. Or pick one of the Garrett G30 turbine housings and we'll supply it with the core. This is the reverse rotation version, built for twin-turbo setups running alongside a matching standard rotation turbo, so it must be used with a reverse rotation turbine housing.
