Engine 2JZ-GE

Engine 2JZ-GE Today, Toyota is one of the ten largest and most famous automakers in the world, providing its customers with exceptionally high-quality cars. The heart of any car is the engine, since it is its characteristics that largely reflect the indicators of speed and power, so the study of any model begins with the engine. One of the latest developments of Japanese engineers was the 2JZ-GE engine, the latest model of which allowed the company to reach a qualitatively new stage in its development, providing its owners with almost unlimited opportunities.

History of occurrence

The JZ series automobile engines appeared in the early 90s, when Japanese designers decided to make a number of improvements, resulting in a distributor ignition system, distributed fuel injection, and 6 longitudinal cylinders. One of the main achievements that was achieved was an increased engine power of 200 hp, despite the fact that the engine capacity was 2492 cm2 (2,5 liters).

Engine Specifications 2JZ-GE

Engines of the 2JZ-GE series are installed on Toyota cars of the following brands:

  • Height AS300, Lexus IS300;
  • Aristotle, Lexus GS300;
  • Crown, Crown Majesta;
  • Crest;
  • Chaser;
  • Mark II Tourer V;
  • Progress;
  • Soarer, Lexus SC 300;
  • Supra MK IV

Regardless of the brand of car, all the characteristics of the 2JZ-GE can be represented as follows:

Volume3 l. (2997 cc)
Power max.225 HP (at 6000 rpm)
Maximum torque298 Nm at 4800 rpm
DesignSix-cylinder in-line engine
Compression ratio10.6
Bore86 mm
Piston stroke86 mm



In general, it should be noted that the Toyota 2JZ-GE has a fairly high reliability, since the distributor installation was replaced by the DIS system with a coil for two cylinders. In addition, after additional equipment of the engine with VVT-i valve timing, the car became more economical in terms of fuel consumption.

No matter how thoughtful the engine is, each of them has its own specific disadvantages, which usually appear after the start of active operation of the car. As many motorists note, one of the most common problems is a malfunction of the one-way valve, which, due to a loose fit, leads to the passage of crankcase gases into the intake manifold. The result of this is not only a decrease in vehicle power by up to 20%, but also rapid wear of the seals. At the same time, the operational repair of the 2JZ-GE in this respect comes down to replacing the PCV valve with a later modification, due to which the performance and power of the car are restored.

Summing up all of the above, it should be said that today the most modern and thoughtful engine is the 2JZ-GE vvt-i, which has an additional electronic engine monitoring system. In general, the GE series engines have proven themselves very well, as evidenced by the numerous reviews of car owners about the operation of the motor.
