A comprehensive makeover for the VK Black engine was completely dropped in favour of an imported 3.0 litre RB30E straight-six unit designed and manufactured by Nissan in Japan. This featured an overhead camshaft (OHC) and an alloy cylinder head. The reason for the Nissan-Holden combination was because all cars manufactured in Australia from 1 January 1986 had to run on unleaded 91 octane fuel. The previous six-cylinder Black motor was unable to do this, as was the V8, hence the later release date of this engine. As the tooling for the Holden straight-six engine had become worn by this stage, it also was not considered cost-effective to adapt the design to unleaded petrol. The new engines included features such as an Electronic Combustion Control System (ECCS) and a ram-tuned intake manifold.

Six months into its release a 150 kilowatts (200 hp) turbocharged RB30ET version of the Nissan engine was released. The Garrett turbo unit was fitted inside a water-cooled housing to ensure longevity. The engine received new pistons which lowered the compression ratio, while an updated camshaft was used to reduce overlap. The allure of the Commodore was quickly established particularly when the top speed was 200 kilometres per hour (124 mph) and then extended to 220 kilometres per hour (137 mph) with the addition of the Garrett turbocharger.

In addition stopping power for the turbo models was upgraded to larger brakes and Girlock finned alloy front calipers. The Australian Police commissioned the turbocharged models as their "interceptor" Highway Pursuit cars of choice. These interceptors were denoted by "BT1" in the model code on the Body & Option plate attached to the firewall.

GM also sourced a Jatco electronic four-speed automatic. Those that opted for a manual received 5-speed Nissan gearboxes. The turbo and non-turbo variants designated MX7 and MF5 respectively.

Irrespective of transmission, Power was sent to the rear wheels through a Borgwarner 28-Spline (Turbo variants)/25-spline open center (non-turbo variant) with a 3.45 or 3.23 Final Drive ratio with a Limited-Slip version available as an option. This was taller than the ratio offered in the Nissan Skyline(3.70 Manual, 3.889 Auto) which utilised the same power plant. (Source: Wikipedia)
