WARNING: Maximum allowable turbocharger speed is 125krpm. 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.

Compressor Map & Exhaust Flow Chart
Exhaust Flow Chart
G Series G40 is available in 2 compressor inducer sizes. G40-900 (62mm) and G40-1150 (71mm) You can click the hyperlinks to go directly to those product pages. Both G40 models are interchangeable meaning they are the same size and can be swapped out without having to reconfigure any other turbo kit parts.
G40 Turbine Housing Kits
G40 turbine housing kits are available in four A/R. 0.85 A/R | 0.95 A/R | 1.06 A/R | 1.19 A/R stainless steel housings with T4 divided inlet flange and V-Band Inlet. The largest 1.19 A/R T4 turbine housing flows 43 LBS/MIN of air which is a 16% increase over the GTX4088R turbine wheel.
Here’s how G40 G42 Compact and GTX4088R stack up against each other in size.
