GARRETT 880547-5022S SUPER CORE G55-2900 106MM

G Series: A Turn Ahead Of The Competition

G Series G55 turbochargers feature the latest innovations in turbocharger technology. Advanced compressor and turbine aero offer a range of high horsepower performance boosting solutions for 3.0L – 12.0L engine platforms. 85mm, 88mm, 91mm, 94mm, 98mm, 102mm, 106mm compressor inducer sizes produce up to 2900 horsepower for today’s top drag race teams.

Center Housing:

One-piece aluminum center housing reduces supercore weight. The center housing is air cooled, features a 16mm ceramic dual ball bearing for premium rotor dynamics, and retains the oil inlet and outlet specifications from previous GTX designs.

Compressor Stage:

Garrett G55 compressor stages are offered in 85m, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm inducer sizes each with their own horsepower ratings indicated in the model name.

Ceramic Dual Ball Bearing

An oil restrictor is recommended for optimal performance with ball bearing turbochargers. G55 turbochargers utilize a massive 16mm dual ball bearing cartridge with steel cages. An oil pressure of 40 – 45 psi at maximum engine speed is recommended to prevent damage to the turbocharger’s internals. In order to achieve this pressure, a restrictor with a 0.040” orifice will normally suffice, but you should always verify the oil pressure entering the turbo after the restrictor in insure that the components are functioning properly. Recommended oil feed is -3AN or -4AN line or hose/tubing with a similar ID. As always, use an oil filter that meets or exceeds the OEM specifications.

WARNING: Dear customer - G series turbochargers are highly efficient units that don't require a high boost for reaching its limits.  Please pay attention that maximum allowable turbocharger speed is 165krpm ( G series ) . The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating a speed sensor, part numbers  781328-0004 (single speed sensor that should be connected) or GARRETT G-SMART MODULE ( Module | Harness | Flange Speed Sensor G-Series ) must be fitted and monitored during fine and tune as well as with use of the unit. Missing of the sensors or RPM data will void  warranty on product.
