Features

  • 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.
  • 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)

Compressor Aero

  • 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

Speed Sensor

The compressor housing features a fully machined ported shroud to help reduce compressor surge. A fully machined speed sensor port provides enthusiasts the option to add the new G Series speed sensor to measure turbocharger shaft speed, a key factor in determining ideal operating conditions.

The new speed sensor is easy to install and does not need to be adjusted for length like previous sensors. Simply remove and plug, then insert the speed sensor and tighten the bolt. The new speed sensor is sold separately and is not compatible with GT and GTX sensors due to the new design and sizing. The addition of an o-ring between the compressor housing and backplate reduces the possibility of boost pressure leakage.

Center Housing

  • 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

Turbine Wheel Aero

  • 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

Turbine Housings

  • 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
Horsepower: 475 - 1200
Displacement: 2.0L - 7.0L
  • GARRETT® G SERIES COMPRESSOR AERODYNAMICS FOR MAXIMUM HORSEPOWER
