Performance & Application

This GT2871R configuration is designed to deliver strong power potential while retaining the responsive spool characteristics that make the GT28 series a favorite among performance builders. The dual ball bearing core reduces bearing friction for quicker spool and improved transient response compared to journal bearing designs. The anti-surge compressor housing helps maintain compressor efficiency and stability at higher boost levels and wider operating ranges. With its T3 undivided turbine housing and V-band outlet, this turbo is suited for builds targeting significant horsepower gains without giving up drivability.
