by

The Toyota IS300 is a beloved platform among car enthusiasts, especially when it comes to swapping in the legendary 2JZ-GTE engine. This powerhouse is known for its incredible performance potential, but to truly unleash its capabilities, you’ll need to consider several supporting modifications. In this article, we will explore the ultimate support mods for the IS300 2JZ-GTE swap, focusing on boost, internals, and suspension.

Boost Mods for the 2JZ-GTE Swap

Boost modifications are crucial for maximizing the performance of your 2JZ-GTE engine. Here are some essential components to consider:

  • Turbocharger Upgrade: Upgrading to a larger turbo can significantly increase horsepower. Popular choices include the Garrett GTX series or the Precision Turbo options.
  • Intercooler: A high-quality intercooler will help reduce intake air temperatures, improving efficiency and power. Look for options like the Mishimoto or Greddy intercoolers.
  • Boost Controller: An electronic boost controller allows for precise tuning of boost levels. Brands like AEM and HKS offer reliable options.
  • Exhaust System: A free-flowing exhaust system will reduce back pressure and improve turbo spool. Consider a full turbo-back system from brands like Tomei or HKS.
  • Fuel System Upgrade: Upgrading fuel injectors and the fuel pump is necessary to support higher horsepower levels. Look for injectors from Injector Dynamics and pumps from Walbro.

Internal Mods for the 2JZ-GTE Swap

To handle increased power and boost, internal modifications are essential. Here are some recommended upgrades:

  • Pistons: Forged pistons can withstand higher power levels and boost. Brands like Wiseco and CP offer great options for the 2JZ-GTE.
  • Connecting Rods: Upgrading to forged connecting rods will provide added strength. Look for brands like Eagle or Carrillo.
  • Head Gasket: A thicker head gasket can help prevent blown gaskets under high boost. Consider using a Cometic or ARP head gasket for reliability.
  • Valve Springs: Upgrading valve springs will help prevent valve float at high RPMs. Brands like BC Racing and HKS have solid options.
  • Cams: Performance camshafts can enhance airflow and power. Brands like Brian Crower and HKS offer camshaft kits tailored for the 2JZ-GTE.

Suspension Mods for the 2JZ-GTE Swap

With increased power comes the need for improved handling. Upgrading your suspension will ensure that your IS300 can handle the added performance. Here are some essential suspension modifications:

  • Coilovers: High-quality coilovers allow for adjustable ride height and damping. Brands like BC Racing and Fortune Auto are popular choices.
  • Sway Bars: Upgrading sway bars can reduce body roll and improve cornering. Look for options from Whiteline or Eibach.
  • Control Arms: Adjustable control arms can help fine-tune alignment settings for better handling. Brands like SPC and Megan Racing offer great options.
  • Strut Braces: A front and rear strut brace can increase chassis rigidity, improving handling response.
  • Tires: Don’t forget about tires! High-performance tires will provide the grip needed to handle increased power. Consider brands like Michelin or Bridgestone.

Conclusion

The IS300 2JZ-GTE swap is an exciting project that can yield incredible performance gains. By focusing on boost, internals, and suspension modifications, you can create a well-rounded vehicle that excels on the street and track. Remember to plan your build carefully and choose quality components to ensure reliability and performance.
