You can Turbo just about any motor if setup right including lowering the compression.
When the VH Commodore was on the market ther were Ads everywhere regarding turbos to suit.
One guy had developed a kit specifically for the Torana Hatch. I can't recall if he was selling complete cars or just fitting the turbo. All I can recall is that he stated the 186 red motor was the best to use and with the base kit (low boost) the Torana would do 0 - 100Km/h in 8.0seconds.
Definately see an expert first though ( he or she will tell you to replace the gearbox as it can only just withstand the standard output).
