Holden Commodore VL Turbo
The Holden Commodore VL Turbo, produced from 1986 to 1988, occupies a unique and significant place in Australian automotive history. When Holden needed to replace the aging six-cylinder engine in the Commodore, they made the unexpected decision to source a powerplant from Nissan. The result was the RB30ET, a turbocharged 3.0-liter inline-six that would become one of the most tunable and beloved engines in Australian performance car culture.
The RB30ET produced 204 horsepower in factory form, a significant step up from the naturally aspirated Holden six it replaced. More importantly, the turbocharged Nissan engine responded enthusiastically to modifications, with relatively simple bolt-on upgrades capable of pushing output well beyond 300 horsepower. This tunability made the VL Turbo enormously popular with the Australian aftermarket performance community.
In standard form, the VL Turbo was a genuinely quick car by the standards of the late 1980s. The combination of turbo torque and relatively light weight gave it impressive straight-line performance, while the rear-wheel-drive layout provided the classic muscle car driving experience that Australian buyers demanded. The four-speed automatic was the most common transmission, though the smooth power delivery of the turbo engine made it an acceptable match.
The VL Turbo's racing legacy cemented its iconic status. Tom Walkinshaw Racing campaigned VL Commodores in Group A touring car racing, achieving significant success at Bathurst and in the Australian Touring Car Championship. The racing versions used extensively modified versions of the RB30 engine, demonstrating the potential that enthusiasts would later unlock in their road cars.
The VL series also offered a naturally aspirated 5.0-liter V8 option (shared with the SS model), but it was the turbo six that captured the imagination of Australian enthusiasts. The combination of Japanese engineering precision with Australian muscle car attitude created a unique vehicle that defied easy categorization.
Today, the VL Turbo is one of the most sought-after Commodores among collectors and enthusiasts. Clean, unmolested examples command strong prices, while modified examples with significant power upgrades have their own devoted following. The VL Turbo represents a pivotal moment in Australian automotive history, when the country's car culture began to embrace forced induction and Japanese engine technology alongside the traditional V8 muscle car formula.
The RB30 engine's compatibility with later Nissan RB25 and RB26 turbo components has created an entire industry around VL Turbo modifications. Some of Australia's fastest street and drag cars use the VL Commodore as their platform, demonstrating the enduring potential of this remarkable combination of Australian body and Japanese engine.
Rust is the primary concern, particularly in the front rails, sills, and rear wheel arches. The RB30ET engine is robust if maintained but check turbo condition, oil system, and head gasket integrity. Many VL Turbos have been modified; ensure modifications are quality work. Unmodified, original-condition examples are the most valuable. Check for previous racing history or heavy modification that may have stressed the drivetrain. Calais VL Turbos are worth more due to higher spec. HSV Group A variants are extremely valuable.
The RB30ET engine was sourced from Nissan's Decherd, Tennessee plant and shipped to Holden's Elizabeth factory in South Australia. The decision to use a Nissan engine was controversial at the time but proved technically sound. VL production ran from 1986 to 1988. The Calais variant offered a higher trim level with the same mechanical package. HSV (Holden Special Vehicles) offered the Group A SV variant with enhanced performance.
