Differences Between 1JZ and 2JZ?

[LeHarley]

The main differences between the two are the number of turbos and the displacement. The 1JZ is a single-turbo 2.5-liter engine, while the 2JZ is a twin-turbo 3.0-liter engine. The 1JZ has a displacement of 2.5L, and the 2JZ has a displacement of 3.0L. 1JZ and 2JZ are two engine codes developed by Toyota, named 1JZ-GTE VVT-i and 2JZ-GTE, respectively. The 1JZ was introduced by Toyota in 1990, weighing 207 kg. It features an inline 6-cylinder, 2.5-liter displacement, with a compression ratio reduced to 9:1. It delivers a maximum horsepower of 280 hp and a maximum torque of 362 N·m. The 2JZ was introduced as early as 1991 and, besides the "Supra," was used in many Toyota models as a powertrain. It weighs 230 kg and features an inline 6-cylinder, 3.0-liter displacement, with a compression ratio of 8.5:1. In terms of power, it further improves upon the 1JZ, delivering a maximum horsepower of 280 hp and a maximum torque of 433 N·m in stock condition. As engines with immense modification potential, the 1JZ and 2JZ have long been favorites among car modification enthusiasts. The 1JZ can handle up to 700 hp in stock condition, while the 2JZ can handle up to 800 hp. However, due to environmental and policy reasons, both the 1JZ and 2JZ have been discontinued.
