by

The IS300 is a popular platform for enthusiasts looking to swap in the legendary 2JZ-GTE engine. This powerful engine, originally found in the Toyota Supra, offers incredible performance potential. However, to fully harness the capabilities of the 2JZ-GTE, several upgrades are essential. In this article, we will explore the top upgrades focusing on clutch, transmission, and cooling solutions.

Clutch Upgrades

A reliable clutch is crucial for handling the increased power and torque from the 2JZ-GTE. Here are some top clutch upgrades to consider:

  • Single Disc Clutch: A high-performance single disc clutch is often sufficient for moderate power levels and offers a balance of drivability and performance.
  • Multi-Disc Clutch: For those pushing serious horsepower, a multi-disc clutch can provide the necessary grip and heat dissipation.
  • Upgraded Flywheel: An aluminum or lightweight flywheel can reduce rotational mass, improving throttle response and acceleration.
  • Clutch Line Upgrade: Consider upgrading to a stainless steel clutch line to improve pedal feel and reduce flex.

Transmission Solutions

The transmission is another critical component in the IS300 2JZ-GTE swap. The right transmission can significantly enhance performance and reliability. Here are some recommended upgrades:

  • Getrag V160 Transmission: This transmission is a popular choice among 2JZ-GTE enthusiasts due to its strength and ability to handle high horsepower.
  • W58 Transmission: For a more budget-friendly option, the W58 can be used, but it may require frequent upgrades to handle increased power.
  • Short Shifter: An aftermarket short shifter can improve shifting speed and feel, enhancing overall driving experience.
  • Transmission Cooler: Adding a transmission cooler can help maintain optimal temperatures, especially during spirited driving or track use.

Cooling Solutions

Keeping the 2JZ-GTE cool is vital for performance and reliability. Here are some top cooling upgrades to consider:

  • Upgraded Radiator: A high-performance radiator can improve cooling efficiency, especially in high-temperature environments.
  • Intercooler Upgrade: An upgraded front-mount intercooler can significantly reduce intake temperatures, improving performance.
  • Oil Cooler: An oil cooler helps maintain optimal oil temperatures, which is essential for engine longevity.
  • Cooling Fan Upgrade: Consider installing high-flow electric fans to enhance airflow and cooling capacity.

Conclusion

Upgrading the clutch, transmission, and cooling systems in your IS300 2JZ-GTE swap is essential for maximizing performance and reliability. By investing in these critical components, you can ensure that your vehicle not only performs well but also stands the test of time. Whether you are a seasoned enthusiast or a newcomer to the world of performance upgrades, these enhancements will help you achieve your goals.
