Get ready for a wild ride as we delve into the story of Mark Psaila's HR Premier, a true automotive time capsule. The 1990s may feel like a distant memory, but this car is a living testament to the era's spirit of customization and performance.
Mark, a true enthusiast, has been the proud owner of this 1966 Holden HR Premier for over 25 years. It's a journey that began in the late 90s when he acquired a stock two-owner car. But this wasn't just any old ride; Mark had big plans to transform it into a powerhouse.
Initially, he swapped in a fiery 208ci red six with triple carbs, setting the stage for a series of engine upgrades. From a mild Chevy 350 small-block to a mighty 434ci small-block from Trick & Mansweto, the HR's heart was constantly evolving. The result? A staggering 680hp on the dyno, and a jaw-dropping 1000hp with nitrous. But Mark wasn't done yet.
The HR wasn't just about brute force; it had style too. Mark gave it a custom paint job in House of Kolor Sunset Pearl orange, a true head-turner. However, life got in the way, and the car sat dormant for 15 years. But Mark's passion couldn't be contained, and he decided to bring the HR back to life with a new vision.
And here's where it gets controversial... Mark chose to go against the grain, opting for a turbocharged 3.0-litre Toyota 2JZ six-cylinder engine. A bold move, considering the HR's V8 heritage. But Mark, being the adventurous type, wanted to do something different. He explains, "I've done the V8 thing, and I like trying new things." A wise choice, as the DOHC JZ engine is renowned for its ability to deliver immense power and torque.
The engine's nickel-tough bottom end is a key part of its legendary status. With an iron block, boost-friendly compression, and beefy conrods, this engine can easily double its factory 280hp rating with a stock bottom end. Mark's engine, although stock for now, has been enhanced with a Yamaha-designed cylinder head, oversized Ferrea valves, and solid lifters, ensuring it's ready for a serious power upgrade in the future.
The hardware is impressive: a massive Garrett G42 turbo, a custom six-into-one Pro Mod-style manifold, a Plazmaman Pro Series intake, and a Haltech R5 Nexus ECU. All controlled by a Haltech PD16 PDM and tuned by Dale Heiler. Running on E85, the turbo 2J produces a mighty 529rwhp on just 21psi, spinning the tires at an incredible 7000rpm. Mark laughs, "Not much happens until 5000rpm with these cams and that turbo, but it's all there for when I put the big motor in."
Mark's vision for his HR is bold: he aims to run seven-second ETs and take on the mighty GT-R Skylines at roll racing. It's a testament to his passion and the enduring appeal of the Toyota 2JZ engine. So, what do you think? Is Mark's HR Premier a bold step forward, or a controversial departure from tradition? We'd love to hear your thoughts in the comments!
