1977 Holden Torana A9X
Created to dominate local touring car racing, the A9X came from Holden with a 400-odd horsepower 5L V8. The car was updated through homologation packages in 1978 and 1979 and famously won every bloody race it entered, killing Australian touring car racing for two years until new regulations banned the A9X package and forced drivers to race with the stock LX Torana Hatchback.
1978 Holden Torana A9X IMSA
In 1978, Bob Forbes, a Sydney based racing driver, started a campaign to build a twin-turbo A9X and, with a group 5 bodykit, race the car at LeMans, nowdays he thinks it was a stupid idea, but people got behind it and 13 lightweight A9X shells were produced before the project was canned, with the cars going to other A9X running teams.
My entry is a direct copy of the planned figures for the A9X IMSA project, with a 600hp Twin Turbo V8 and aluminium panels, if the car comes anything other than last, I will be highly suprised!
