Garrett G42-1200 Turbocharger

Turbo Features

• Garrett G Series compressor aerodynamics for maximum bhp.
• 73mm turbocharger compressor wheel.
• Fully machined ported shroud to help reduce compressor surge.
• Stainless steel turbine housings in T4 and V-Band connections.
• New turbine aero provides higher flow and efficiency.
• Water fittings included.
• Fully machined speed sensor and pressure ports.


2.0L - 7.0L

The G-Series G42-1200 turbocharger is compatible with 2.0L to 7.0L engine displacements and capable of producing up to 1200 horsepower.

New compressor and turbine aero combined with high-temperature resistant materials allowed engineers to push the limits of performance.

• 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 with the option to add the new G Series speed sensor to measure turbocharger shaft speed, a key factor in determining ideal operating conditions.

Oil Passage
• Twin-piston rings on both sides of the shaft reduce the likeliness of oil leakage from the centre housing to the compressor or turbine stage.
• A new oil deflector redirects oil away from the compressor stage seals reducing the possibility of oil leakage through the seals.
• 10mm ceramic dual ball bearing cartridge (Same as GTX42).

Turbine Wheel
• 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 a peak efficiency of 77%.
• 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 / 1742 deg F.
• 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.
