Get ready for a wild ride with Mark Psaila's turbocharged HR Premier, a true automotive time capsule! In a world where nostalgia often takes a backseat to the latest trends, Mark's dedication to his 1966 Holden HR is a refreshing blast from the past.
For those who fondly recall the 1990s, a time when petrol prices were a distant memory, Mark's story is a testament to the enduring passion for classic cars. Despite the ever-changing automotive landscape, he's kept this HR Premier as his trusty companion for over 25 years, a true testament to his commitment.
First featured in the January 2026 issue of Street Machine, Mark's journey with this car is a tale of evolution and innovation. He began by keeping the HR stock, but his love for performance soon kicked in. From a hot 208ci red six to a Chevy 350 small-block, and then a massive 434ci small-block, the HR's engine bay has seen it all. But Mark wasn't done yet.
"I wanted to give the HR a new lease of life, so I decided to go for a bold look with big radials and a powerful turbocharged engine," Mark explains. "It was time to bring some serious attitude to the streets."
The transformation was extensive. Mark turned the four-door into a sleek two-seater, with a custom rear clip and an integrated roll cage for added rigidity. The body, now gun-barrel straight, was painted in the original Landale Gold, a color that harkens back to the HR's factory days, but with a modern twist - a black roof.
But the real star of the show is under the hood. Mark opted for a turbocharged 3.0-liter Toyota 2JZ six-cylinder engine, a decision that sparked controversy among car enthusiasts. "I wanted to do something different," Mark says. "The 2JZ is renowned for its power and torque, and I wanted to see what it could do in this classic Holden."
The DOHC JZ engine has a legendary reputation for its ability to produce massive power and torque. With an iron block, high compression, and sturdy factory components, these engines are built to last. Mark's 2JZ has been modified with a Yamaha-designed cylinder head, oversized valves, and upgraded cams, ensuring it's ready for the big power Mark plans to unleash.
A massive Garrett G42 turbo, a custom manifold, and a Haltech R5 Nexus ECU control the engine's performance. The intake and fuel system are designed to feed the thirsty 3.0-liter engine with E85, resulting in an impressive 529rwhp on just 21psi of boost. Mark's HR is a true force to be reckoned with.
"The power doesn't kick in until 5000rpm, but when it does, it's an exhilarating experience," Mark grins. "I can't wait to see what this car can do with the big motor I have planned."
Mark's HR Premier is a unique blend of classic style and modern performance. With the aim of running seven-second ETs and taking on the mighty GT-R Skylines at roll racing, Mark is pushing the boundaries of what a classic Holden can achieve.
So, what do you think? Is Mark's decision to go with a turbocharged 2JZ a stroke of genius or a controversial move? Let us know in the comments! We'd love to hear your thoughts on this wild HR Prem.
