2JZ - the legendary Toyota engine

Toyota's subsidiary Tahara Plant produced the 2JZ engine for sixteen years ( 1991 - 2007 ). This three-liter inline-six was created for rear-wheel drive such as the Mark 2 , Crown and Aristo . Later, the internal combustion engine was modernized, equipped with VVT-i variable phases and DIS-3 ignition .

Fuel consumption

Let's consider how much gasoline a 2JZ engine consumes using the example of two cars of the same model, but of different generations.

Lexus GS300 1st generation

Lexus GS300 with a 4-speed automatic transmission and rear-wheel drive consumes per 100 km :

1. city ​​– 13.1 l ;
2. highway - 10.2 l ;
3. average - 11.8 l .

Lexus GS300 2nd generation
Rear-wheel drive Lexus GS300 of the second generation with 2JZ and 5 automatic transmission has fuel consumption:

1. urban cycle – 16,4;
2. suburban cycle – 8,8;
3. mixed – 11,6.

Motor modifications

Toyota 2JZ was produced in three variations .

• 2JZ-GE – the first base motor (1991—1997 G.). Aspirated has power 220—230 hp (depending on settings) at compression ratio 10,5. Upgraded version, which appeared at the end of the decade, equipped with VVT-i, three ignition coils, was different firmware and other little things. However, the power did not change after the update.

• 2JZ-GTE – tailored for a sporty driving style turbocharged modification. This engine was very different from the base 2JZ: pistons, designed for a low compression ratio, camshaftshaving rise 7.8 And 8,4 mm, other phase, and of course CT20 superchargers And intercooler. Thanks to the changes, the power has increased up to 280 horses, and the moment up to 432 Nm. Export motors were even more powerful were different from intra-Japanese to others turbines, big raising the camshafts, injectors And phase. They gave out 321 hp And 441 Nm. Later in 1997 this internal combustion engine too equipped with VVTi. Torque has risen up to 451 Nm, but the power remained the same.

three-liter JZ engine differs from the previously appeared 2.5-liter an increased piston stroke ; in addition, the cylinder block has grown by 14 mm . There were no other obvious differences.

2JZ-GE engine cylinder head

Above the six-cylinder block there is a cylinder head and 24 valves . There are no hydraulic compensators, timing drive is belt driven . Intake manifold 2JZ variable geometry.

Timing belt drive 2JZ-GE

Modernized in 1997. VVTi was installed at the intake, and the old distributor ignition was replaced by DIS-3.

Technical characteristics of the 2JZ-GE engine

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

• Altezza AS300, Lexus IS300;
• Aristo, Lexus GS300;
• Crown, Crown Majesta;
• Cresta;
• Chaser;
• Mark II Tourer V;
• Progress;
• Soarer, Lexus SC 300;
• Supra MK IV

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

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

Service

The 2JZ engine is enviably reliable. The manufacturer claims a resource of 300 thousand mileage. Often, with proper care and careful operation, the engine will last 500 thousand kilometers before major repairs.

Proper maintenance and compliance with 2JZ maintenance schedules are important for any engine. In this case, the list of routine maintenance:

• Changing the engine oil every 10 thousand km. When operating at high speeds or if the car spends most of its time in city traffic jams, you should not delay replacing it, or even better, do it earlier. The manufacturer recommends using only original oil from Toyota with viscosity 5w-30 or 5w-40. To replace you will need from four before five liters lubricants

  
  It is recommended to use original Toyota oil SAE 5w-30 or 5w-40

• The valves do not suffer due to a broken belt, but still drive The 2JZ timing belt needs to be monitored. Once 15-20 thousand km inspect visually for damage, change every 100 thousand.

• Simultaneously with replacing the belt, the 2JZ valves are adjusted. The gap is set using adjusting washers.

  
  Engine valves 2JZ-GE

• New antifreeze is added periodically 60,000 km or in three years, depends on which comes first. In this case it is necessary to check pipes, seals And pump for tightness.

• Fuel and air filters have the same replacement period of 40,000 km .

Disadvantages and weaknesses of the 2JZ engine

The 2JZ engine does not cause any major problems. In older internal combustion engines, excessive lubricant consumption . The reason for the oil leak is trivial - worn valve stem seals or rings .

VVT-i valve for 2JZ-GE engine

The VVTi phase regulator is the weak point of the design. Therefore, when buying a car with an engine manufactured after 1997 , you should carefully check the functionality of this system. Its service life is just over a hundred thousand kilometers .

The electronic components of the engine contain a bunch of sensors that from time to time refuse to work and require replacement.

Timing belt tensioner roller

Another disadvantage of the 2JZ is the short service life of the pump and timing belt tension pulley . The internal combustion engine is prone to flooding spark plugs . You must remember to adjust the valves and ensure that no water gets into the ignition system.

The 2JZ engine was produced in several modifications

• The 2JZ FSE series engine is an analogue of the previous 1JZ series engine. Produced from the beginning of the century until 2007. It has a power of 217 horses and a compression ratio of 11.3. Fuel is supplied to the cylinders by direct injection under pressure. This method of fuel supply practically does not improve technical characteristics, but has a positive effect on reducing fuel consumption and the content of harmful substances in the exhaust. The power of this modification is 217 horses. The 2JZ series engine was always equipped with an automatic transmission. It was installed on Toyota Brevis, Progres, Crown
• TOYOTA engine 2JZ GE series - the largest quantity of this modification was produced. It produces 220 horsepower at 6,000 rpm and 298 lb-ft of torque at 4,800 rpm. The injection of the fuel mixture is phased (sequential), that is, when the crankshaft is rotated 180°, a specific injector corresponding to the injection phase is activated. The classic order of operation of the TOYOTA engine cylinders of the 2JZ GE model is 1-4-3-2. The cylinder block is cast iron, the head is aluminum. At first, it was equipped with a standard DOHC timing system, with two camshafts and 4 valves per cylinder.

Subsequently, they began to install a system for regulating the gas distribution phases, DIS ignition, in which one ignition coil was intended for each pair of cylinders. This modification was designated 2JZ GTE VVTi.

Compared to 2JZ GE non VVT-i configurations, engines equipped with a variable valve timing system have improved traction performance at low speeds. The phases are controlled using a special clutch mounted on the camshaft.

As the engine speed of the 2JZ GTE increases, the VVT-i valve opens and the camshaft changes position in relation to the drive pulley and, accordingly, changing the position of the pushers, and they open the valves earlier and close later. The power of the 2JZ GE VVTi remains the same, but the torque increases as the speed increases.

The engine of the 2JZ GE model was equipped with TOYOTA Altezza, Aristo, Crown, MarkII, Chaser, Cresta, Progress, Soarer, SupraMKIV, Lexus 300 series IS, GS, SC cars. Currently, when converting cars, in some car service centers they install 2JZ on UAZ and GAZelle.

• The 2JZ engine of the GTE modification is perhaps the most advanced engine in the 2JZ line. In the nineties of the last century, TOYOTA Supra MK4 began to come off the assembly line, on which they began to install the 2JZ GTE engine with VVTi.

Tuning

The 2JZ engine has a large margin of safety. , more than 1000 horses can be removed from it . Although there is no point in tuning the basic 2 JZ-GE, it is easier to buy a car with a sports GTE . But nothing prevents you from removing 450 forces from it . You can do it like this :

• Buy and install turbo kit, which is based on 30th Garrett. The kit includes all the additional elements, but you will have to tinker with their installation.

  
  Garrett G30-770 G-Series 3071R Turbo

Install the piston group from the GTE . If this is not available or if you want to save money, you can increase the volume of the combustion chamber by installing a thick 3 mm gasket under the block head.

• Add to this an 80mm throttle body.
• Nozzles from 550 to 630 cc.
• Performance fuel pump, e.g. Walbro 255.

  
  Walbro fuel pump 255 l/h

• Tune your brains. There is firmware for this purpose Greddy E-Manage.

  
  Greddy E-manage Engine Control System

Of course, this tuning is not for budget-conscious people. The kit will not be cheap, and after modifications, fuel consumption will increase .

But the twin-turbo 2JZ-GTE is beloved by tuners. There are several options for increasing power. The simplest is to increase the boost pressure . Without changing the turbine, you can achieve 1.2-1.3 bar . In this case, elements of attached equipment . They do this:

• They install injectors that produce about 550 cc of performance.
• The fuel pump is capable of pumping from 250 liters of fuel per hour .
• Flashing the control unit.

This method can increase the power rating to 400 hp.

Turbocharging GReddy

To achieve the same power of 400 horses , but at the same time get a more even torque, install a turbo kit :

• Two small turbines are replaced with one large one from Garrett.
• In addition, injectors with a capacity of 1000 cc , another intercooler , two Walbro fuel pumps and a throttle with a diameter of 80 mm .
• In addition, camshafts with higher valve lift , wide valve timing, reinforced valve springs , an equal-length exhaust manifold, a 3-inch exhaust pipe and a tuned intake manifold can be supplied. And also change the control unit and configure it. When setting up, pay close attention to the ignition. Later will blow away the spark, and early will promote detonation.

Turbo Kit for 2JZ-GE Garrett G30-660 Turbo, 6 boost Manifold & 50mm Turbosmart GENV Wastegate
These changes remove up to 800 horses . Not enough for you? Then change the pistons to forged ones , the connecting rods to reinforced ones and modify the cylinder head . It’s not enough again and you want to squeeze more than 1000 horsepower ? In this case, change the compression ratio, install a lighter flywheel and switch the unit to gasoline with a higher octane rating.

Detailed description of 2JZGTE

The 2JZ GTE modification engine was received in 1997 by installing a turbocharger with a side intercooler on the GE version. The first units, after modernization, received a torque of 435 Nm. Then, another upgrade was made by installing dual turbochargers. The 2JZ GTE modification with Twin Turbo increased its torque to 451 Nm and power to 276 horses.

As a result, the 2JZ GTE has characteristics that vary between markets. In the USA and Europe, cars are supplied with power up to 320 hp, and for the Japanese domestic market the power was limited to 280 horses, in accordance with their legislation.

The 2JZ engine of the GTE VVTI modification is equipped with a sports manual six-speed gearbox V161 and V160 (Getrag engineers took part in the development), or a comfortable four-speed automatic A341E.

Basically, the 2JZ engine of the GTE VVTi model was installed in the TOYOTA Aristo and Supra.

The idea of ​​​​creating a three-liter engine was borrowed by Toyota from Nissan, with its RB series of engines. The in-line engine operates more balanced compared to its V-shaped counterparts, for example the same Toyota UZ FE.

In V-shaped engines, the pistons move in two planes located at an angle relative to each other, which is where imbalance occurs. These engines run longer, faster, and torque changes more smoothly.

As already mentioned, the power of the 2JZ engine of the GTE VVTi model can easily be increased almost three times without serious tuning, due to its thoughtfulness.

All the details that affect the operation of the engine under extreme loads are taken into account - effective lubrication, valve mechanism, cast iron cylinder block (instead of the common aluminum) everything was designed and created to withstand extreme operating conditions. One of the interesting and extraordinary design solutions is that the diameter of the piston has the same value as its stroke.

What cars was 2JZ installed on?

The list of cars with a 2JZ engine under the hood can be stretched over several pages. Here is a partial list of Toyota models with this unit:
