The Garrett G42-1450 Dual Ball Bearing Turbo Is a Beastly Mid-Frame Turbo
The largest mid-frame turbo in the G-series lineup, Garrett's all-new G42-1450 is a beast. It's designed to boost power well beyond the needs of many drivers, and that makes kit one of the most impressive options out there. It can help produce between 525hp and 1450hp in engines ranging in displacement from 2.0L to 8.0L. If your project doesn't quite call for a turbo with this output, then consider the G42-1200 as another option for big power.Â
Using an all-new 98mm compressor wheel aero to achieve a whopping 77% peak efficiency and +10% flow gains over GTX42 with no compromise. The improved ported shroud inlet design offers maximum surge resistance with huge flow rates in a compact outline. Flowing 136 lb/min with a Max turbo speed of 114krpm and max exhaust gas temp is 1050C/1922F. The G42 Compressor housings use a traditional 5" inlet and 3" outlet with a fully machined speed sensor port. Â

G42-1450 Turbine Flow
Dual Ball Bearing CHRA
All G-series turbos utilize a vband turbine housing to CHRA connection. This improves ease of installation, clocking and servicing 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. We recommend you 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 peak efficiency of 74%.

About Garrett G-Series Series Turbochargers
Garrett G-Series turbochargers are designed specifically for the hard-core enthusiast who wants optimal performance. The forged fully-machined billet aluminum compressor wheels feature next generation aerodynamics that provide 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 water cooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Inconel, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures.
