In Australia, new ProCharger kits for popular V8s typically run about AUD 8,000–15,000 for the hardware before installation.
Drive‑away installed pricing usually lands around AUD 12,000–20,000 depending on intercooler size, fuel system bits, and tuner wizardry.
Used head units or second‑hand kits tend to float between AUD 2,000–6,000, plus whatever brackets, belts, and a fresh tune you’ll inevitably need.
Budget another AUD 1,000–2,500 for dyno time and tuning, and consider clutch or transmission cooling if you enjoy torque the way Aussies enjoy a long weekend.
Factor in GST, shipping, and any engineering/emissions approvals, because paperwork loves boosted engines almost as much as you do.
