Just Autos Package 3 Overview

  • 🚀 The Just Autos Package 3 is designed to be the benchmark in performance for the 70 Series, focusing on both maximum power and reliability.
  • 🎯 This top-tier package transforms a typical 70 Series from approximately 145 horsepower and 350Nm to around 300 horsepower and 950-1000Nm.
  • ✅ It ensures the vehicle pulls hard, holds gears on the highway, and maintains reliability and optimal temperatures for towing and touring.

Key Performance Upgrades

  • ⚡ The core of the package is the JA300 turbo upgrade, a genuine brand new Garrett Turbo, which makes around 300 horsepower at 28-31 pounds of boost.
  • ⚙️ A 1600Nm clutch is critical to handle the increased torque, preventing clutch slip when carrying loads.
  • 💨 The system includes a 4-inch intake pipe with a true 3-inch down to the turbo, designed to work with the JA300, and a 4-inch exhaust from Fat Pipes for improved sound and aesthetics.

Enhanced Cooling and Airflow

  • 🌬️ The Just Autos airbox is a full aluminum design, utilizing the factory filter, with a huge inlet for stainless steel and Safari snorkels, ensuring a proper seal.
  • ❄️ A Just Autos fan kit is installed on top of the factory cooler to reduce intake temperatures, leading to lower turbo speeds, better density, more power, and improved fuel consumption.
  • 🇦🇺 Both the airbox and fan kit are 100% Australian made, with the fan kit featuring high-quality special fans, Deutsch connectors, and solid-state relays.

Advanced Tuning and Reliability

  • 🧠 The package incorporates multi-mapping capabilities, offering various modes like a flat map (stock), towing (optimized for long trips), power (most common for maximum power and drivability), and Cal Plus (with launch control and lumpy auto).
  • 🛠️ The JA300 turbo is a re-engineered Garrett unit, with replaced and balanced compressor and turbine wheels and a 36-degree bearing, ensuring superior performance and reliability.
  • 🛣️ This package is specifically designed for tours and agricultural use, catering to those who need significant power while maintaining critical reliability for long-distance work.
  • 🇦🇺 Package 3 is available through Just Autos and their distributor network across Australia.
