In this post, we will explore the top performance upgrades that can unleash the full power and versatility of the Toyota 300 Series Land Cruiser, transforming it into a true off-road powerhouse. Whether you crave adrenaline-pumping adventures or are simply looking for an elevated driving experience, the team at Just Autos have got you covered. Read on to learn more!

Why You Should Upgrade Your 300 Series

Toyota vehicles have undoubtedly earned a reputation for being some of the most capable and reliable machines on the road. Yet, while Toyota’s diesel engines boast reliability, some enthusiasts crave an extra punch of power. Fortunately, with the right modifications and adjustments, these engines have the potential to unleash a level of power and torque that is genuinely impressive.

Exhaust Upgrades

Put simply, performance exhaust upgrades refer to the process of upgrading all or part of your vehicle’s stock exhaust system. The exhaust system of your 300 series plays a crucial role in the overall performance and efficiency of the vehicle and is responsible for guiding the exhaust gases away from the engine. This offers a number of benefits including:

  • Enhanced Sound And Feel
  • Improved Airflow For a Boost in Power and Performance
  • Improved Fuel Efficiency For longer Adventures
  • Reduced Weight
  • Better Vehicle Aesthetics

Airbox Upgrades

Looking to give your LC300 a performance boost? An aftermarket airbox is the ideal solution for quick and effortless improvement. Upgrade to an aftermarket airbox assembly for your Toyota 300 Series Land Cruiser, and you’ll see a significant enhancement in airflow compared to the factory airbox, especially when tuning your engine.

By opting for an aftermarket airbox, you not only boost airflow but also address a common issue with Toyota’s airboxes – the seal. Toyota’s airboxes, including those in the VDJ200 of the 200 Series Land Cruiser, are notorious for lacking a robust seal. This deficiency leads to a phenomenon called ‘dusting’, where dust and harmful pollutants infiltrate the airbox and wreak havoc on your vehicle’s internal components. By opting for an aftermarket airbox, you ensure a better seal, safeguarding your engine from potential damage caused by dust and debris.

Heat Exchanger Upgrade

While the factory-standard intercooler and cooling systems in the Toyota 300 Series Land Cruiser serve their purpose, demanding circumstances can push the engine to high temperatures. As a result, the factory ECU resorts to under-fuelling the engine to protect itself, leading to decreased power and torque at the wheels.

Fortunately, heat exchanger upgrades can easily mitigate this issue. This upgrade seamlessly complements the existing cooling components and provides additional water-to-air cooling capabilities. The results are impressive, as the cooling capacity of your existing components significantly increases.

  • Tow Loads with Ease
  • Effectively Regulate Engine Temperatures
  • Integrates Seamlessly With Upgraded & Factory vehicles
  • Maintains Torque Outputs

Custom ECU Remapping

At Just Autos, we pride ourselves on being at the forefront of innovation and performance enhancements. Prior to the release of the 300 series, we had the privilege of gaining access to the 300 series ECU, offering unparalleled insights into its capabilities.

During our extensive testing, we discovered that the 300 series comes significantly under-tuned from the factory. That is why, when you are looking to upgrade the performance of your Toyota, ECU remapping is one of the best solutions.
