WARNING: Maximum allowable turbocharger speed is 102.5krpm. 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 can be installed into the compressor housing to monitor shaft speed. Sensors sold separately. (click here for details)

Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The horsepower numbers represented above are calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel horsepower.

Additional G45 Configurations

G Series G45 is available in 3 additional compressor inducer sizes. G45-1125 (67mm), G45-1350 (72mm), and G45-1500 (76mm) You can click the hyperlinks to go directly to those product pages. All G45 models are interchangeable meaning they are the same size and can be swapped out without having to reconfigure any other turbo kit parts.

 

G45 Turbine Housing Kits

G45 turbine housing kits are available in four A/R. 1.01 A/R | 1.15 A/R | 1.28 A/R | 1.44 A/R stainless steel housings with T4 divided inlet flange. Our 1.44 A/R T4 turbine housing flows 57 LBS/MIN of air which is a 14% increase over the GTX45 turbine wheel.
