Features

• GARRETT G SERIES COMPRESSOR AERODYNAMICS FOR MAXIMUM HORSEPOWER
• 73mm TURBOCHARGER COMPRESSOR INDUCER
• COMPACT COMPRESSOR HOUSING SAVES SPACE
• FULLY MACHINED SPEED SENSOR AND PRESSURE PORTS
• NEW TURBINE WHEEL AERO FOR INCREASED EFFICIENCY AND FLOW
• STAINLESS STEEL TURBINE HOUSINGS IN V-BAND AND T4 CONNECTIONS
• WATER FITTINGS INCLUDED
• 1200 HORSEPOWER CAPABLE
• CFD (computational fluid dynamics) engineered compressor wheel
• Optimized blade contour with 10 blade count
• Forged and fully-machined compressor wheel
• More power and faster boost response
• Smaller wheel = lower inertia
• Garrett® G42-1200 available with compact housing and standard housing
• Garrett® G42-1450 available only with standard housing
• (A) Fully machined ported shroud to help reduce compressor surge.
• (B) A fully machined speed sensor port provides racers the option to add a speed sensor. Comparing shaft speed and boost levels on a compressor map will help determine ideal operating conditions to ensure peak power over a wider operating range.
• (C ) The fully machined pressure port.
• Sold separately, the Garrett ® G Series speed sensor kits have new part numbers and are not compatible with GT/GTX kits. Easier to install and will not need to be adjusted for length like previous sensors. Simply remove bolt that secures the plug, insert the speed sensor and re-tighten the bolt.
• Aluminum backplate for reduced weight (GTX42 Steel)
• Includes (2) -6AN water fittings
• Center housing to turbine housing Vband connection makes installation easy for installers. (Same Vband as GTX42 / GTX45)
• GTX and GT turbine housings are not interchangeable
• Full 360 degree orientation of compressor housing and non wastegated turbine housings
• An o-ring between the compressor housing and backplate reduces any boost pressure leakage
• Twin piston rings on both sides of the shaft reduce the likeliness of oil leakage from the center housing to the compressor or turbine stage.
• A new oil deflector redirects oil away from the compressor stage seals reducing possibility of oil leakage through the seals.
• 10mm ceramic dual ball bearing cartridge (Same as GTX42)
• The turbine wheel features all new aerodynamics to improve flow and boost response.
• Inconel super alloy construction for temperatures up to 950C
• New turbine wheel flows 10% more and has peak efficiency of 77% (Compared to GTX42 at 74% with 1.01A/R)
• 82mm inducer / 75mm exducer 84 Trim
• G42 turbine housings are made from stainless steel to provide ultimate durability and temperature capability up 950 deg C degrees | 1742 deg F
• B&C qualified
• GTX and GT housings not interchangeable.
• Turbine housings are available in V-band, open, free float configurations for launch
• V-band inlet is 3.6 inch / 92mm ( compared to GTX30/35 3 inch / 76mm
• V-band outlet is 4.3 inch / 109mm
