Understanding the 2JZ-GTE Engine

The 2JZ-GTE is a 3.0-liter inline-six engine that features a twin-turbo setup. It was originally designed for the Toyota Supra MK4 and has gained a legendary status in the automotive community. Its iron block and aluminum DOHC head provide a solid foundation for high horsepower builds.

Essential Upgrades for 700+ HP

1. Turbocharger Upgrade

To reach 700+ horsepower, upgrading the turbocharger is crucial. Consider these options:

  • Precision Turbo 6266
  • Garrett GTX3582R
  • HKS GT-RS

2. Fuel System Enhancements

A robust fuel system is essential for supporting high horsepower. Key upgrades include:

  • Upgraded fuel injectors (1000cc or larger)
  • High-flow fuel pump (e.g., Walbro 450)
  • Fuel pressure regulator

3. Engine Management System

A proper engine management system (EMS) allows for precise tuning. Popular options include:

  • AEM Infinity
  • Haltech Elite
  • MoTeC M1

4. Exhaust System Upgrade

An efficient exhaust system helps reduce back pressure and improve performance. Consider:

  • 3-inch stainless steel downpipe
  • High-flow catalytic converter
  • Cat-back exhaust system
