Built with nearly indestructible internals, this twin-turbo inline-six from Toyota offers endless modification potential. Tuners love the 2JZ TT engine because it responds exceptionally well to upgrades—whether through larger turbochargers, upgraded fuel systems, or advanced engine management. Capable of handling over 1,000 horsepower on stock internals, it’s often used in professional drag and drift cars. The 2JZ TT engine also has vast aftermarket support, making parts and tuning options readily available. Its deep, aggressive exhaust note and linear powerband give it a driving feel that’s both raw and refined. Whether in a Supra or a custom swap project, the 2JZ TT engine remains the ultimate foundation for creating high-performance machines that never compromise on reliability.
