The Toyota Supra, particularly its fourth generation, gained near mythical status among car enthusiasts, and much of its acclaim can be traced back to its extraordinary powerplant—the 2JZ engine. A paragon of performance, the 2JZ engine is revered for its capacity for horsepower and remarkable endurance. Its inline-six configuration, along with a robust iron block, provides a sturdy base for upgrades and modifications, consistently delivering performance that outstrips engines with a similar displacement.
Our experience with the 2JZ engine confirms its legendary status in the automotive world. Its design seems tailored for those who thirst for more power and torque. Seven main bearings with just two bolts each offer a surprisingly strong foundation, while the closed deck design of the iron block lends the engine exceptional rigidity. These characteristics are not just for boasting but are verified through decades of tuning and motorsport achievements.
Performance aficionados and professional tuners agree that the potential for significant horsepower gains without sacrificing reliability is what sets the 2JZ apart. From its stock form to highly modified examples, the 2JZ can handle substantial levels of boost with ease, a testament to Toyota’s engineering acumen. Whether for competitive racing or street performance, the 2JZ continues to be the choice for those who prioritize power and resilience.
