The JZ series among Japanese motors became famous for its not fully disclosed capabilities. For tuners, such engines are a godsend. The 1JZ GTE is a turbo version of the classic 1JZ GE. It operates on two turbines, developed jointly with Yamaha.
Description of the engine 1JZ GTE
Most powerful Jayzet motor. The 1JZ GTE is a turbocharged version that develops 280-320 hp.
The engine was first released in 1990. Since 1996, they began to refine the cylinder head, new intelligent systems for switching the phases of the gas distribution station and cooling appeared. In 2003, the "six" 1JZ GTE was replaced by an aluminum and more modern 4GR-FSE.
The 1JZ GTE engine is a turbo version that inflates 0.7 bar. On this motor, the piston group was replaced, and the cylinder head was developed jointly with the Yamaha company. The motor was fitted with standard camshafts. In 1996, a modification was carried out, as a result of which two turbines were replaced by one. The VVTi system appeared for a smoother increase in revs, and the compression ratio was increased to 9. The power of the power unit after restyling did not change - 280 hp. from. However, the potential made it possible to increase the indicator to 320 liters. from. without a full-fledged chip.
The first generation of the engine used two turbines with parallel compressors (twin-turbo). The intercooler was under the wing of the car, from where it was connected to the motor. The second generation used one larger CT 15B turbo. Notably, the latest universal coated valve gaskets are now available. It was titanium nitride, which reduces the friction of the camshaft lugs.
The 1JZ GTE engine has 4 valves per cylinder, the timing drive is of a belt type. A broken belt does not bend the valve (except for the FSE version), which makes the 1JZ GTE a motor with a long service life. There are no hydraulic lifters on the engine.
Service regulations
- Change the oil in the engine every 5-10 thousand kilometers. Fill in 4.5-5.4 liters of oil, depending on the drive of the car. It is recommended to decide in advance which oil to pour. The characteristics of the lubricant should be within 0W-30 / 10W-30;
- Replace the timing belt at least every 100 thousand kilometers;
- It is imperative to adjust the valves every 100 thousand km manually, using dummy washers.
- belt tension;
- ignition timing;
- cylinder head condition;
- the state of the turbocharging system;
- eFI fuel injection system;
- electrical equipment.
Fault overview 1JZ GTE
Learn more about problems and solutions:
- If Dzhizet's "six" does not start, you must first check the candles. They can be filled in, then you need to unscrew the elements and dry. In general, this turbo version is afraid of cold weather and moisture, so washing must be done carefully;
- If the engine is troit, then the main reason for the restyled version is related to the ignition coils. In addition, on engines with a new Toyota gas distribution system, the reason may be hidden in the valve;
- If the speed is floating, it is necessary to check the valve of the gas distribution system, the XX sensor or the throttle valve. In most cases, the motor again functions like a clock after flushing the clogged elements;
- If the engine consumes a lot of fuel, the cause must be looked for in the oxygen sensor. It is also recommended to check the quality of the filters;
- If the internal combustion engine knocks, then this is more often caused by a failure of the gas distribution clutch. Unfortunately, its resource is small. Valves requiring manual adjustment can also knock. Excessive sounds are also created by worn connecting rod bearings, as well as a problematic belt tensioner bearing;
- If there is a high oil consumption, then this is due to mileage. This problem is standard on 1JZ GTE, associated with wear on the valve stem seals and rings. Although it would be more correct not to do major repairs at very high mileage, but replace it with a contract one.
One of the problematic parts of the 1JZ GTE is the water pump. On jayzets, the pump does not last long, as does the viscous coupling. Another problem is the position of the second generation engine spark plugs. Each of the sparking elements is endowed with an individual coil. This causes the valve cover to overheat while the motor is running.
The engine oil pump is also considered a problematic part that needs to be replaced ahead of schedule. The reason for this is poor quality oil
Tuning options for the 1JZ GTE engine
The turbo version is rarely modified, since the potential of the engine as a whole is revealed. As for converting 1JZ GTE into 2JZ, the game is not worth the trouble. First of all, the height of the block will not allow this - the size differs by 14 mm, which will force the connecting rods to be shortened. For an internal combustion engine of this type, this is unacceptable, because the load on the piston group will increase and there will be a tendency to oil consumption.
Putting on the Valbro 255 pump, removing the catalyst and building the exhaust on 3-inch pipes, it will be an effective tuning for the turbo unit. The exhaust system should not have any constrictions, you will also need to take care of the cold air intake and increase the boost from 0.7 to 0.9 bar. Further modernization implies already new brains, a special bus controller and an intercooler. The boost will increase to 1.2 bar and the engine power will increase by an extra 100 hp. from.
The Walbro fuel pump is capable of pumping up to 255 liters of fuel per hour. This is a powerful unit that is often used in the tuning process.
The next stage of tuning, which will significantly reduce engine life, is working with a Garrett turbine. Paired with it, you need a regular three-row radiator and a separate oil radiator. You also need to take care of the cold air intake, 80 mm damper and reinforced fuel hoses. The injector should produce 800 cc and the exhaust should be built on 3.5-inch pipes. Thus, it will be possible to increase the power of the internal combustion engine to 1000 liters. from.

List of modifications of the 1JZ series ICE
Consider the engine versions of this series, in addition to the 1JZ GTE:
- 1JZ-FSE D4 is a power unit with a direct injection system. The compression ratio of the engine is 11, the power is 200 liters. from. The modification was produced in the period 2000-2007;
- 1JZ-GE is the basic atmospheric version of the series. Two generations of this ICE were produced. First with a capacity of 180 liters. from. and a compression ratio of 10. The second generation came with VVTi, modified connecting rods and a different cylinder head. The compression ratio was increased to 10.5. The distributor was replaced with ignition coils. As a result, the aspirated power increased to 200 liters. from.

The 1JZ-GE engine can be safely called a legend created by the designers of the Japanese company Toyota. Why a legend? The 1JZ-GE was the first engine in the new JZ line, created in 1990. Now engines of this line are actively used in motorsport and in ordinary cars. 1JZ-GE became the embodiment of the latest technologies of that time, which are still relevant today. The engine has established itself as a reliable, easy-to-operate and relatively powerful unit.

First and second generation
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
As you can see, the toyota 1JZ-GE is not turbocharged and the first generation had a distributor ignition. The second generation was equipped with coil ignition, 1 coil was installed for 2 candles, and a VVT-i valve timing system.
1JZ-GE in Toyota Chaser
1JZ-GE vvti - the second generation with variable valve timing. The variable phases allowed to increase the power by 20 horsepower, smooth the torque curve, and reduce the amount of exhaust gases. The mechanism works quite simply, at low speeds the intake valves open later and there is no valve overlap, the engine runs smoothly and quietly. At medium revs, valve overlap is used to reduce fuel consumption without losing power. At high revs, the VVT-i provides maximum cylinder filling for increased power.
The first generation engines were produced from 1990 to 1996, the second generation from 1996 to 2007, all of them were equipped with four and five-speed automatic transmissions. Installed on:
- Mark II Blit;
- Chaser;
- Cresta;
- Progres;
- Crown.
Maintenance and repair
JZ series engines run normally on 92 and 95 gasoline. On 98th, he is worse to start, but has high productivity. There are two. The crankshaft position sensor is located inside the distributor, there is no starting nozzle. Platinum spark plugs need to be replaced every 100,000 kilometers, but to replace them, you will have to remove the top of the intake manifold. The volume of the engine oil is about five liters, the volume of the coolant is about eight liters. Vacuum air flow meter. The one located near the exhaust manifold can be reached from the engine compartment. The radiator is cooled as standard by a fan attached to the water pump shaft.
Overhaul of 1JZ-GE may be needed after 300 - 350 thousand kilometers. Naturally standard maintenance and replacement of consumables. Probably the sore spot of the engines is the timing belt tensioner, which is only one and often breaks. Problems can also arise with the oil pump, if it's simple, then it is similar to the VAZ one. Fuel consumption with moderate driving from 11 liters per hundred kilometers.
1JZ-GE in JDM culture
JDM stands for Japanese Domestic Market or Japanese Domestic Market. This abbreviation formed the basis of the world movement, which began with the JZ series engines. In our time, probably, most of the engines of the 90s are installed in drift cars, since they have a huge power reserve, are easy to tune, simple and reliable. This is confirmation that 1jz-ge is a really good engine, for which you can safely pay money and are not afraid that you will stop at the side of the road on a long journey ...
