Garrett G25-550 Reverse Rotation Turbocharger (P/N 877895-5007S)Brand new genuine Garrett G Series G25-550 reverse rotation turbocharger. The G25 is Garrett's clean-sheet small-frame ball-bearing design — it supersedes the GTX2860R Gen II and flows roughly 10 lb/min more (about a 22% gain) from the same compact footprint. The reverse-rotation version is built for symmetrical twin-turbo setups and installs with tight routing constraints. Horsepower: supports up to 550 HP Compressor wheel: forged, fully-machined 48mm inducer / 60mm exducer with G Series aerodynamics and ported-shroud inlet for surge resistance Turbine: Mar-M alloy turbine wheel rated to 1050°C with stainless turbine housing Bearing system: ball-bearing cartridge Compressor housing: 3" inlet / 2" hose outlet with fully machined speed-sensor and pressure ports Rotation: reverse — pair with a standard-rotation G25 for a mirrored twin install Note from Garrett: maximum allowable shaft speed is 185k RPM — running beyond it risks damage and premature failure. A speed sensor (sold separately) can be installed in the compressor housing to monitor shaft speed.JDM Alliance is an authorized Garrett dealer — every unit is brand new and factory-sealed.
