Garrett G Series G30-770 – Reverse Rotation
The Garrett G Series G30-770 Reverse Rotation Brings Big Power in a Small Frame
Garrett’s Reverse Rotation G30-770 is a mirror image of the all-new G30. A clean-slate ball bearing turbo with state-of-the-art G series aerodynamics, this turbo is compact yet outflows all comparable products on the market. It's also one of the best in the entire G Series lineup. Before you jump to the G30-900, make sure to check out the G30-770. Carrying nothing over from the old gen GT/GTX—the G-series 71mm exducer billet compressor wheel redefines what we thought was possible for a given airflow range—flowing +10 lbs/min (+22% gain) compared to the outgoing GTX3071R Gen II turbo it supersedes.
G30-770 max turbo speed is 150krpm and the max temp is 1050C/1922F. G30-770 Compressor housings use a traditional 3″ inlet and 2″ hose outlet with a fully machined Speed Sensor Port. The Improved ported shroud inlet design offers maximum surge resistance with huge flow rates in a compact outline. Available in standard rotation and reverse rotation options for enthusiasts that want the perfect twin turbo installation or a single reverse rotation turbo for applications with installation restrictions. This turbo is sold as a complete assembly with supercore and turbine housing

G30-770 and G30-990 Dyno Graphs
Below you’ll see a dyno graph comparing a Gen2 GTX3076R with a .83 a/r hot side VS G30-770 with a .83 a/r hot side, same car, same boost pressure. This is on a stock RB25 tuned with pump gas.
Understanding the Name
A new name designates a new generation of industry-leading technology and innovation. In G30-770 “G” designates 81 years of Garrett Turbo heritage, “30″ classifies the frame size. The remaining 3 digits identify the “max horsepower” rating at the flywheel of the turbocharger (ie 770).
Available in standard rotation and reverse rotation options for enthusiasts that want the perfect twin turbo installation or a single reverse rotation turbo for applications with installation restrictions. The CFD (computational fluid dynamics) engineered compressor wheel increases airflow up to 15% for 60mm with 79-80% efficiency (Compared to GTX GenII).
Dual Ball Bearing CHRA – Standard and Reverse Rotation
All G-series turbos utilize a v-band turbine housing to CHRA connection. This improves the ease of installation, clocking, and servicing of the turbo. Each turbocharger includes (1) -4AN oil restrictor fitting with a 1mm restriction orifice to provide the turbo with the recommended 40psi of oil pressure. Four large water jacket ports increase cooling capacity and allow enthusiasts to customize water line routing to help improve the installation process. The turbocharger comes with two -6AN water fittings and two plugs. Recommended to install waterlines on opposite sides of the housing.
G-Series Turbine Wheel and Housing
The G-series turbine wheels feature all-new aerodynamics to improve flow and boost response. The industry-leading design is made of Mar-M super alloy and is capable of handling exhaust gas temperatures up to 1050 degrees C. The new G25 turbine wheel flows 15-20% more than GTX and has a peak efficiency of 74%.

About Garrett G-Series Series Turbochargers
Garrett G-Series turbochargers are designed specifically for hard-core enthusiasts who want optimal performance. The forged fully-machined billet aluminum compressor wheels feature next-generation aerodynamics that provides a larger horsepower range and maximize boost response.
Ported shroud compressor housings increase surge resistance and provide reliable, continuous power throughout the power band. A dual ceramic ball bearing cartridge prolongs the lifespan and improves shaft balance. The watercooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Mar-M, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures.
