context_page_description: The Holden straight-six motor is a series of straight-six engine that were produced by General Motors–Holden's in Australia between 1948 and 1986. The initial Grey motor was so dubbed because of the colour of the cylinder block, later motors came in the form of a Red, Blue, Black, and the four-cylinder Starfire engine. These engines were fitted to all Australian designed Holdens of the same years, and the four-cylinder Starfire notably also found its way into the Toyota Corona. The Grey motor is a different engine from the others, while the Red, Blue, Black, and even the Starfire are all inter-related with many common parts and castings.
context_section_description: This 1.9-litre (1,892 cc) powerplant, known as the Starfire engine, was effectively Holden's existing 2.85-litre 173 cu in straight-six with two cylinders removed. Designed and built in Australia to satisfy local content rules, it first appeared in 1978 during the UC Sunbird's production run, replacing the Opel 1.9-litre cam-in-head unit used in LH, LX and earlier UC Torana/Sunbird 4-cylinder models.
  Peak power output for the Starfire was 58 kW (78 hp), with a 17.5 second acceleration time from 0–100 kilometres (0–62 mi) in the VC Commodore. This variant's performance meant the need to push the engine hard leading to fuel consumption similar to the straight-sixes. Due to this, it was often nicknamed as Misfire or Backfire. This engine was replaced in the Australian market by the Camira's OHC Camtech unit, however, it continued to be used until 1986 in New Zealand, where it was used to power four-cylinder versions of the VK Commodore.
  This engine was also used by Toyota Australia to meet local parts content regulations for the Corona XT130. Engines installed in Toyotas received some slight differences in the form of a unique camshaft, manifold, and carburettor. Toyota called the engine the "1X" and it had a slightly different power curve: 58 kW (78 hp) at 4800 rpm and 136 N⋅m (100 lb⋅ft) at 2400 rpm.
