Is the Lexus GS 300 a 2JZ?

Yes, the Lexus GS 300 is equipped with a 2JZ engine. The 2JZ is a legendary inline-six engine produced by Toyota that has become a popular choice for enthusiasts and tuners due to its reliability and tuning potential.


Detailed Explanation


The Lexus GS 300 is a luxury sedan that was produced by Toyota's premium brand, Lexus, from 1993 to 2005. During this time, the GS 300 was powered by Toyota's 2JZ-GE engine, a 3.0-liter inline-six cylinder engine that is renowned for its robust design and impressive performance capabilities.


The 2JZ engine was first introduced in the Toyota Supra in 1986 and quickly gained a reputation for its exceptional reliability and tuning potential. The 2JZ-GE variant found in the Lexus GS 300 was a naturally-aspirated version of the engine, producing around 220 horsepower and 210 lb-ft of torque.


While the 2JZ-GE in the GS 300 was not as powerful as the turbocharged 2JZ-GTE found in the Supra, it still offered a compelling blend of performance, refinement, and reliability that made the GS 300 a popular choice among luxury sedan buyers.


Tuning and Modifications


One of the key reasons the 2JZ engine has become so popular among enthusiasts is its exceptional tuning potential. With the right modifications, the 2JZ can be coaxed to produce significantly more power than its stock configuration, making it a favorite among the tuning community.



  • Common modifications include upgrading the turbocharger, improving the engine's cooling system, and installing high-performance engine management systems.

  • With the right upgrades, it's not uncommon for 2JZ-powered vehicles to produce over 500 horsepower, making them true performance powerhouses.

  • While the Lexus GS 300 was not typically the focus of extensive tuning efforts, the 2JZ engine's popularity has led some enthusiasts to modify their GS 300s to extract more performance from the iconic inline-six.


Overall, the Lexus GS 300's use of the legendary 2JZ engine is a key part of its appeal and legacy among enthusiasts and car enthusiasts alike.
