A Turn Ahead Of The Competition G Series Performance Turbochargers

Garrett® G Series 42 turbochargers offer enthusiasts a new range of quick spooling, high horsepower solutions for 2.0 liter up to 8.0 liter engine platforms. The G42-1200 Compact, G42-1200, and G42-1450 turbochargers produce up to 1450 horsepower thanks to the ten blade, forged, fully-machined G Series compressor wheel with high flowing aero. These low inertia compressor wheels are smaller in size and weight resulting faster boost response. (compared to GTX42) Garrett® G42-1200 is available in standard V-band, and compact compressor housing options. The V-band compressor housing is outline interchangeable with GTX42 while the new Compact option is 4mm shorter axially and 29mm smaller radially (FigA). The G Series turbine wheel features all new aerodynamics to improve flow and boost response. New turbine aero wheel flows 10% more and has peak efficiency of 77% (Compared to GTX42 at 74% with 1.01A/R). Engineered with inconel super alloy to withstand operating temperatures up to 950C. Stainless steel turbine housings are available with V-band inlet and outlet connections in free float mono-scroll options. Divided, free float, T4 turbine housings will be available in 2019.

• To differentiate a new generation of turbochargers.
• Frame size is our most common identifier (GT30 | GT35 ect)
• Identify max power capability.
• Garrett® to be used before all turbo models (Garrett®G42-1200| Garrett® G42-1450)
• IP- model names and numbers are hard to protect.
• TM protects brands | ® protects the appearance, not the function
•  

• Internally nothing changes in 3D drive or to part numbers. Naming is an external facing change.

• -  9 assembly kit part numbers
• -  3 V-band turbine A/R
• -  1.01 | 1.15 | 1.28
• - Non-wastegated / free float
• -  Monoscroll / Open Volute
• - Standard rotation only

Technology and Features 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

 

 

---

 

Technology and Features Compressor Housing 

 

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. 

 

 

 

Speed Sensor Kits

G Series Street Kit: 781328-0003 (includes speed sensor, wire harness, gauge)

G Series Pro Kit: 781328-0004 (includes speed sensor, wire harness)

Technology and Features 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

 

 

---

 

Technology and Features Rotating Group

- 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)

Technology and Features G42 Turbine 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

Technology and Features G42 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

 

• T4 Divided turbine housing options coming Q1 2019.
