This Holden Colorado was built by Harrop Engineering in Preston, Victoria, Australia. The company worked close with Killa Conversions & Performance to offer their own LSx powered Colorado called the Superado. They started by replacing the factory 2.8 L Duramax LWN turbo diesel inline-four and 6L50E six-speed automatic with a 6.2 L LSA V8 with and 6L80E six-speed automatic. The upgraded TVS2650 supercharger helps the engine make 516 horsepower and 589 lb-ft of torque to the hubs. The new transmission mates to the factory 4WD transfer case. If you are interested in owing your own LSx-powered Colorado, conversions start at $37K for the base LS3 and climb to $44K for the LSA with TVS2650 supercharger. You can read more about the packages offered here or in the video below.
