General Motors-Holdens developed an overall of 74,627 LC Toranas. LJ In February 1972, the facelifted LJ Torana was introduced with the six-cylinder designs now aesthetically related to the bigger Holden HQ series. Keep Checking Back Here were shared with the LC, with the significant modifications limited to the option of engines.
The 2250 and 2850 engines rollovered into the revised six-cylinder Torana models, and the 3300 engine (called the 202 in the HQ variety) was adopted as the engine for the LJ Torana GTR sedan. Gearbox choices remained the exact same across the range. A race-bred variation of the 3300 engine was also fitted to the LJ Torana GTR XU-1, producing well over 200 brake horsepower.
75in CD triple carburettors, as well as a new close ratio M21 4-speed Australian made transmission, this offered the active XU-1 the power boost it required to seriously challenge the powerful Ford Falcon GTHO Phase III, which had won the 1971 Hardie-Ferodo 500 production vehicle endurance race held every year at Bathurst.
This would be the start of the 'Peter Perfect'/ Torana legend, and the very first of five Bathurst wins for the Torana in its colourful 10 year racing profession at Bathurst. Holden likewise developed a 308ci V8-powered variation of the GTR XU-1, often described as the GTR XU-2, however the car never ever made it past the prototype phase.
This was the result of a media frenzy that was reporting against these future released "bullets on wheels" available to the public. In effect, all 3 producers acquiesced this pressure, and Holden would delay its introduction of a V8 Torana for two years up until the release of the a little larger LH series Torana in 1974.
An overall of 81,813 LJ Toranas were developed by Holden in Australia, with some exported to New Zealand, but just in 6-cylinder kind, likely due to the comparable 4-cylinder Vauxhall Viva HC range being sold there also. The 2850SL model, with container seats and 4-speed flooring shift, or Trimatic three-speed automated was also shipped to New Zealand in CKD kit type for regional assembly from 1973, ending up being the very first Kiwi-built Torana.
