Holden Colorado RG, Colorado 7, Trailblazer | 2.8L Duramax | 2013 On
The Garrett Motion PowerMax GTB1752VKL is a direct bolt-on upgrade for the 2.8L Duramax in the 2013-on Holden Colorado RG, Colorado 7 and Trailblazer. It brings modern G-Series compressor wheel aerodynamics to a factory-fit package. No custom fabrication required.
Around 20% more flow than the OE turbo, with a wider compressor map for better performance across the rev range. It will run on the factory calibration, but a quality tune is what unlocks the gains.
Power and Boost
On a chassis dyno with a modified ECU and the OEM fuel system, this turbo supported around 160kW, up from the OE 147kW. Results vary with tuning and supporting mods.
- Forged, fully machined G-Series design compressor wheel for higher efficiency

Frequently Asked Questions
Do I need a tune?
Recommended. The turbo will bolt on and run on the OE calibration, but a quality ECU tune unlocks the flow and drivability gains.
What supporting mods help?
A healthy fuel system, clean intake and intercooler piping, good intercooler efficiency, and a free-flowing exhaust help realise the gains.
Is this truly bolt-on?
Yes. It is outline interchangeable with the OE turbo, so it fits the factory location and connections.
Will it affect towing temps?
With the right calibration and supporting cooling, expect improved response and efficiency, which can help manage EGTs.
