Holden Commodore VL Turbo

Holden Commodore VL Turbo

The Holden Commodore VL Turbo is one of the most culturally significant and technically interesting Australian cars of the 1980s, born from an unlikely marriage between General Motors-Holden and Nissan that initially outraged Holden purists but ultimately created an enduring legend. When Holden's own inline-six engine could not meet forthcoming emissions regulations, the company made the controversial decision to source a replacement from Nissan — the RB30E and its turbocharged sibling, the RB30ET. The result was a car that would fundamentally reshape Australian performance car culture.

The RB30ET engine that powered the VL Turbo produced 204 horsepower in factory trim, a figure that was competitive but not extraordinary for 1986. What made the engine special was its construction. The iron block was massively over-engineered, with main bearing caps held by six bolts rather than the usual four, and the bottom end could reliably handle power outputs far beyond the factory specification. Australian tuners quickly discovered that with a larger turbocharger, upgraded fuel system, and a boost controller, the RB30ET could produce 300, 400, even 500 horsepower while retaining factory-like reliability. This tuneability transformed the VL Turbo from a fast family sedan into the foundation of Australia's turbocharged street car scene.

The transmission options reflected the car's dual personality. The four-speed Jatco automatic was smooth and suited the car's grand touring character, while the five-speed manual (available only in the Turbo model) appealed to enthusiasts who wanted to exploit the engine's wide power band. Both transmissions drove the rear wheels through a solid differential — an arrangement that made the VL Turbo a devastating drag strip performer and an entertaining sideways companion for those who understood rear-wheel-drive dynamics.

The VL's chassis was conservative but effective. MacPherson struts up front and a live axle at the rear were hardly cutting-edge, but Holden's engineers had decades of experience tuning this layout for Australian conditions. The Turbo variant received firmer spring and damper rates, a thicker front anti-roll bar, and four-wheel disc brakes — a significant upgrade over the drum rear brakes of lesser VL models. The result was a car that handled its power with reasonable composure, although the live rear axle could be caught out by mid-corner bumps.

The VL Turbo's legacy in Australian automotive culture cannot be overstated. It spawned the legendary Walkinshaw Group A SV, a homologation special that became one of the most valuable Australian cars ever produced. The aftermarket scene that grew around the VL Turbo was enormous, with companies like Turbonetics, HKS, and local Australian firms developing complete performance packages. The RB30ET's compatibility with parts from the later RB25DET and RB26DETT engines from Nissan Skyline GT-Rs created a tuning ecosystem that persists to this day.

In terms of collectibility, the VL Turbo market has exploded in recent years. What were once considered outdated family sedans are now recognized as the cars that defined a generation of Australian performance enthusiasts. Factory-original, low-kilometer examples command premium prices, particularly manual transmission cars in desirable colours. The Calais Turbo, with its more luxurious trim level, is also highly sought after. For many Australians of a certain age, the VL Turbo was the car on their bedroom wall — and that emotional connection drives values ever higher.
