1JZ Engines for sale

The Toyota 1JZ is a 2.5-liter, inline-six engine produced from 1990 to 2007, serving as the smaller sibling to the legendary 2JZ. Renowned for its smooth power delivery, high-revving character, and robust construction, it powered the Toyota Supra, Mark II, Chaser, Cresta, Soarer, and Crown.

The 1JZ-GTE features sequential twin turbochargers that provide responsive low-end torque. Its short-stroke design allows for a high 7,500 rpm redline, giving it a distinctly different character from the torque-focused 2JZ. Like its larger sibling, the 1JZ is over-engineered and capable of 500+ hp with modifications. While never officially sold in North America, it remains a beloved swap candidate and JDM icon for its durability, smoothness, and tuning potential.
