What cars have the jz engine and what is good about this voracious engine. What cars have the jz engine and what is good about this voracious motor 2jz gte vvti technical characteristics

Initially, the 2JZ-GTE engine is associated with the Toyota Supra, and the Supra, in turn, is a descendant of the Toyota Celica Supra. Initially, Toyota produced a car under the Celica Supra brand, and later the company divided into the Supra and Celica brands.

Starting from the 4th generation, Supras (MKIV) were equipped with a 2JZ-GTE producing 280 hp. , and for the American market (USDM) 330 hp. The engine was invented more than 25 years ago, why is it so popular?

1. We don’t kill him!

2JZ turbo— easily withstands critical loads under which other engines simply burst at the seams. 1000 horsepower is far from the limit for him. And to increase the power by 50% without investing fabulous money into it, what engine can boast of such a thing?

2. Get 700 hp. on 2JZ-GTE

The recipe is simple:

• Replacing the turbine and manifold with a more efficient one
• Replacing the fuel pump and injectors
• Front intercooler
• Replacing the Engine Control Unit (ECU)

That's all it takes. In this case, you do not need to get into the piston group. Everything there can easily withstand this power.

3. Get 2000 hp on 2JZ-GTE

In this case, everything is a little more complicated, but if desired, it is quite doable.

At a minimum you need:

• Replacing the turbine, manifold with something very large
• Replacing camshafts
• Forged pistons
• Reinforced, H-shaped, forged connecting rods
• Stroker kit 3.4 liters
• Refinement of the engine head
• Injectors that can provide the required amount of fuel

It is unlikely that any of you will come up with the idea of ​​removing 2000 hp, but if it does, it is possible!

4. Reliability of 2JZ-GTE

If you are not a fan of powerful engines, but just want to get around the city with a comfortable, powerful engine, then this Japanese engine will surprise you with its unpretentiousness. Almost nothing breaks in it, and for decades now it has been working, moving from car to car. Change the oil, filters and fill up with gasoline, have fun - that's all you need to do :)

5. 2JZ-GTE quality in detail

Japanese engineers made this engine with love, thinking through all the nuances. Just look at the oil nozzles, which lubricate the piston to prevent overheating at high speeds.

6. Engine balance 2JZ-GTE

This is an in-line six-cylinder unit (L6). The pistons move strictly vertically and synchronously, making it perfectly balanced. I think that you have more than once come across a video on the Internet where the owners of this engine place a coin edge-on on a running engine and it does not fall. Know that this is not a myth. This is the real work of a working 2JZ-GTE

7. Meeting of valves with pistons on 2JZ-GTE

If the timing belt breaks, the valves do not collide with the pistons, maintaining the serviceability of the engine. If it so happens that the belt breaks while the engine is running, then nothing bad will happen. It will be enough to set everything according to the marks and install a new belt.

8. Cost of spare parts for 2JZ-GTE

Firstly, I would like to note the abundance of spare parts for this engine. There will be no problems with searching even in the most remote regions. All spare parts are available to order and you won’t have to wait long for them. Secondly, the quality of spare parts - they simply do not break even if the load exceeds the factory parameters. Take the oil pump, for example. It can easily handle 1000 hp.

9. Sequential charging system 2JZ-GTE

There is an opinion that this system, innovative for its time, is very problematic - this is not so. Once you quickly familiarize yourself with the principle of operation, everything becomes clear. The 2JZ-GTE has 2 turbines that compress air in series. The turbines are small, which allows them to reach positive pressure at very early speeds. I will surprise you, but at 1800 rpm there is already a positive boost. When the tachometer needle approaches 3000 rpm, the pre-spin valve of the second turbine will open slightly. This was done by the smart Japanese so that there would be no shock loads on the impeller of the second turbine. At 3500-3700 rpm, the second turbine is ready to go into action. 4000 rpm and you feel a confident pick-up and the dynamics of the car change dramatically. In this mode, both turbines operate in parallel. In the city this is simply an irreplaceable system. With it you will forget what a “Turbo pit” is.

10. 2JZ-GTE is cool

This is a really cool engine, it impresses both people who do not understand engines and professional engineers. Just open the hood and you are guaranteed the attention of others.

Motors of the IZ series are today a legend in motorsport due to their endurance and durability. It’s not for nothing that professionals and speed enthusiasts still use motors created in the 80s and 90s. Find out what cars are equipped with the jz engine and why it is so popular.

The first copy of the 1JZ-GE series appeared in 1990. With a volume of 2.5 liters, it produced 180 horsepower and 235 Nm of torque, had a timing drive, an aluminum cylinder head and a cast iron block.

In 1995, the design was slightly improved. Compression increased, phase rotators were added, and the design of the cooling and ignition systems changed. Power began to reach 200 horses.

This is what the 1JZ-GE engine looks like

The engine, with minor modifications, was used in new civilian cars until 2007. It was valued for its great power and ease of use. It was widespread both in Japan and in America, where Toyota constantly supplied its cars.
In 1996, not only the aspirated engine was modernized, but also the supercharged engine.

The cylinder head has changed, stepless phase control has appeared, and instead of 2 small turbines, one large one has appeared. In 2000, both variants were modified by providing direct fuel injection. The engines have become more economical, but their power remains the same.

The engines have a long service life. With regular oil changes and engine maintenance, their service life is 300–350 thousand km, and full repairs are required after a mileage of 500 thousand km.

Reliable 2 JZ motor

The documents indicate that the legendary “jazettes” should operate on 95-octane gasoline, but Russian drivers easily use 92-octane gasoline in naturally aspirated engines. The engine can easily withstand low temperatures and long mileage, but it cannot be called economical with 100% certainty.

Even at calm riding less 10 – 11 liters per hundred Notit turns out. But turbanized optionand completely “gluttonous” - he leasily absorbs from 20 liters.

The 1JZ and 2JZ designs are in demand not only due to their characteristics. They make excellent bases for tuning projects. This is possible due to the large safety margin. The motors can be accelerated to 1000 hp, leaving some of the parts from the stock motors.

Engine from Toyota jz

1JZ and 2 JZ are similar in design, so tuning them is carried out according to the same principle. The two have more power, but the cost of the engine itself is higher, so most projects are carried out on the 1JZ engine - in terms of price-quality ratio, it turns out to be more economical.

Experienced specialists in this method of updating engines try to work mainly with the contract version of GTE.

Toyota Mark II TourerV

Are there any disadvantages?

Even such common motors have their disadvantages:

1. They do not have hydraulic compensators and have valves adjusted by washers. Adjustment is required every 80 - 100 thousand km. This does not affect the power, but maintenance becomes a little more difficult.
2. Weak timing belt tension. According to factory settings, its resource is 100 thousand km, but in practice the rupture may occur earlier.
3. The pump has a short resource according to engine parameters. The water pump can run 150 - 200 thousand km. In cars with "jazettes" it is the first to fail.
4. Low reliability of the viscous coupling. Because of this, the motor can overheat at high voltage.
5. Poor cooling of the 6th cylinder. This applies primarily to 1JZ. The engineers did not calculate the heat removal lines quite correctly.

List of cars on which the engine is installed

The main “carrier” of jz is the Toyota Mark II TourerV, widespread in all Russian regions, and most of all in the Far East and Krasnodar Territory.

5 years back price auto was V within 200 – 220 thousand. rub., Today or she Maybe reach before 400 thousand. rub.

The average mileage of this model in the secondary market exceeds 200 km, so this is a budget car. Drift lovers are especially favorable towards him. They revere the “Mark” in much the same way as the Nissan Silvia and Toyota Supra, equipped with the 2jz engine.

Soarer is a unique machine that will always be valuable

Jayzets were also installed on rear-wheel drive and all-wheel drive Toyota models: Crown, Cresta, Aristo, Lexus GS300, Progress, Soarer and Lexus SC 300.

Conclusion

The jz series engines were born at a convenient time when the automotive industry had reached a high level, as opposed to marketing. Therefore, they were created with conservatism, but at the same time using the latest technologies. This is how 4 cylinder valves, an electric injector, and phase rotators appeared.

The design was successful, with almost no engineering errors. It could have been developed further, but in the 2000s, preferences in the automotive industry changed. Modern cars are more environmentally friendly than cars with a jz engine, but their engines are unlikely to withstand the power of 1000 horses. People for whom this is important continue to drive Jayzettes.

At the end of the last century, Japanese automakers created many sports engines, which, due to their performance, potential and reliability, are considered to be the best to this day. Next, we consider one of them - 2JZ-GTE. Characteristics, design, operating and tuning features are described below.

Story

The JZ engine series replaced the M series in 1990. The power units in question went through two generations during production (in 1996). In 2007, they were replaced by the GR series with a V-shaped layout.

As for the 2JZ-GTE, it was produced from 1991 to 2002.

General Features

The JZ engine series developed by Toyota includes two lines: 1JZ and 2JZ. The main difference between them is the volume and design of the cylinder block. Both engine lines have a six-cylinder in-line configuration. Equipped with a DOCH gas distribution mechanism with 4 valves per cylinder. Designed for use with rear-wheel drive or all-wheel drive transmission and longitudinal arrangement.

The turbocharged version was developed as an analogue of the Nissan RB26DETT sports engine, which appeared two years earlier than the 2JZ-GTE. Its characteristics are very similar, the layout is the same.

Design

JZ engines have two camshafts, 4 valves per cylinder, timing belt drive, and an ACIS variable geometry intake manifold. There are no hydraulic compensators. The 2JZ differs from the 1JZ in its larger volume (3 liters instead of 2.5). Both variants have a cast iron cylinder block, but the 2JZ has a 14 mm higher one. In addition, for the engine in question, unlike the 1JZ, the cylinder diameter and piston stroke are equal and amount to 86 mm. Aluminum cylinder head.

After modernization, both lines of the JZ series were equipped with a VVT-i variable valve timing system.

The 2JZ line included three versions: GE, FSE, GTE. The first is the basic atmospheric option. The second differs from it by the presence of direct injection. The third modification is equipped with turbocharging.

The 2JZ-GTE is equipped with two Hitachi CT20A turbochargers and an intercooler. In addition, connecting rods from the GE version were used, pistons designed for a compression ratio of 8.5, with recesses and additional oil grooves. The camshaft lift is 7.8/8.4 mm, the phase is 224/236. Injectors - 430 cc.

Engines for the foreign market were equipped with CT12B turbines with stainless steel parts instead of ceramic ones, camshafts with a lift of 8.25/8.4 mm and a phase of 233/236, and 540 cc injectors.

The principle of supercharging operation is noteworthy, combining bi- and twin-turbo schemes: one turbine starts working at 1800 rpm, and the second is connected at 4000 rpm.

Performance

The most powerful version of the 2JZ, naturally, is the turbocharged version 2JZ-GTE. Its characteristics were initially 276 hp. With. power at 5600 rpm and 435 Nm of torque at 4000 rpm. This is due to legal requirements.

Due to the slightly modified design of the export versions of the 2JZ-GTE, their performance was higher. Power was 321 hp. With. at 5600 rpm, torque - 441 Nm at 4800 rpm.

During the modernization, as mentioned, the engine was equipped with a variable valve timing system. Thus the 2JZ-GTE VVTi was born. Its technical characteristics have increased compared to the original version. Thus, the torque increased to 451 Nm.

Application

The 2JZ-GTE was used on only two Toyota models. These are Aristo in both generations (JZS147 and JZS161) and Supra (JZA80). On the Aristo it was equipped exclusively with a 4-speed automatic. In addition to it, the Supra offered a 6-speed manual transmission.

Features of operation

The engine life is more than 500 thousand km. It is recommended to fill it with 95-octane gasoline and use 5W-30 oil. The engine holds 5.5 liters of it, consumption is up to 1000 g per 1000 km. The recommended replacement frequency is once every 10,000 km, although it is advisable to carry out this procedure twice as often. The operating temperature is 90 ° C. The service life of the timing belt is 100 thousand km. The valves are adjusted with washers at the same intervals.

Problems

The most problematic part of the engine is the variable valve timing system. Many malfunctions are related specifically to VVT-i: speed tripping and floating (valve), knocking (clutch). In addition, you need to be very careful when washing, since it is easy to fill the spark plugs, as a result of which the engine may not start and may stall. In addition, tripping can be caused by faulty coils. Unstable speed is caused by a clogged throttle valve and idle air sensor or valve. The main reason for increased fuel consumption is a faulty oxygen sensor, filters, or mass air flow sensor. Extraneous sounds (knocking) can be caused by unadjusted valves, connecting rod bearings, or the belt tensioner bearing of attachments. To get rid of excessive oil consumption, replace the valve stem seals and rings. The pump has a short service life.

The main problem parts are the timing tensioner bracket, crankshaft pulley, oil pump seal. In addition, poor cylinder head purging is noted. Possible boost failure.

Tuning

The engine in question has very great potential for tuning. Therefore, this is one of the most frequently modified engines. The high potential is explained primarily by the large safety margin of the 2JZ-GTE. Technical characteristics can be increased by one and a half times without loss of service life and without serious intervention in the design.

In addition, the engine itself is often an element of tuning: 2JZ-GTE is one of the most commonly used engines for swapping.

This engine was first installed in the 1986 Toyota Supra, and since the start of production of the fourth generation model at the end of 1992, the 2JZ-GTE has firmly established itself as the engine of Toyota's sports compacts. The reason for this is the fact that, thanks to its power, even 23 years after the start of production, the engine remains popular both among ordinary car enthusiasts and among racing teams. The volume still remains unchanged - 3.0 liters. With just a few modifications, the 2JZ will produce power that would make almost any production engine jealous.

Where can I find it?

The 2JZ-GTE first came to Japan under the hood of the 1991 Toyota Aristo, and then moved to the Japanese Supra models, and lived there until production of the model was discontinued in 2002.
The 2JZ-GTE has a more affordable brother called the 2JZ-GE. Their design is very similar, but the GE uses high-pressure pistons, and, according to the manufacturer, it only produces 230 hp. In short, you shouldn't be interested in this engine. Just don't think about it, and don't try to look under the hood of the non-turbocharged fourth-generation Supra. The same engine, by the way, is installed in the Lexus IS300, GS300 and SC300 models.

JDM Alternative

In the land of the rising sun you can often find a 2.5-liter 1JZ-GTE engine. Its later versions are distinguished by the presence of phasing of the intake camshaft and the presence of one turbine. By the way, the 2JZ-GTE engine was at one time adapted for the Japanese market by installing computerized valve timing control and a new turbine.

But you and I do not live in Japan or the USA, so we can only dream of a powerful three-liter engine. In any case, JDM engines are much easier to maintain, cheaper and, despite smaller injectors and camshafts, they make about the same power as their American counterparts.

It's all about the block

In developing its 2JZ engine, Toyota took cues from Nissan and their famous RB series of racing engines. Like the RB26DETT engine, the 2JZ uses an in-line design that is naturally perfectly balanced. Unlike V-twin engines, the pistons in the front three cylinders move in the opposite direction to the pistons in the rear three cylinders. Thanks to the polar operation of the pistons, the weight in V6 engines is distributed equally, but the 2JZ cannot boast of such a feature. But one thing about the Toyota engine is that you can rev it harder, longer, smoother and safer than any other engine.

The possibility of doubling engine power would surprise almost any car enthusiast, but in the case of the 2JZ it is possible. If you are looking for an engine that can reach 700 hp. without tearing off the bottom cover, then pay attention to this beauty from Toyota. A cast iron engine with a heavy-duty block cover that prevents any movement of the cylinders, a forged crankshaft, concave pistons and voila, the perfect engine. Seven bearing caps provide excellent support for the crankshaft, and oil sprayers mounted under the pistons keep moving parts cool at high speeds. In addition, the guys from Toyota did a great job with the square geometry of the engine, thanks to which the diameter of the cylinder bore is equal to the length of the piston stroke.

“Other than the timing belt tensioner, crankshaft pulley and oil pump gasket, the engine has virtually no weaknesses,” says one expert from southern California.

Pros and cons of 2JZ-GTE

Advantages:
- Ability to develop up to 2000 hp.
- Rigid in-line design
- Lack of access to the valve actuator
- Durable cast iron body
- Forged crankshaft
- Powerful root neck
- Oil sprayers under the pistons
- Square geometry
- Timing belt, oil pump and cooling system support up to 1000 hp. additional power

Flaws:
- Unreliability of the timing belt tensioning mechanism
- Oil often starts to ooze from the pump
- Unreliability of the crankshaft pulley
- Poor cylinder head design
- Unreliable turbine

How to easily accelerate to 750 hp.

If you believe the guys from FSR Motorsport Creations, then accelerating the engine power by more than 2 times is not so difficult. The first step is to replace the sequential turbo with a larger compressor. Look for a turbo in the 64-88mm range with a good boost pressure regulator and replace the side-mounted intercooler with a front-mounted one. GReddy and HKS make excellent engine modification kits that have all the necessary parts. Additionally, you will need a larger fuel pump, a larger pressure line, 1,000cc fuel injectors, and some good ECU like the AEM Infinity. And finally, a good camshaft from Brian Crower will allow you to squeeze the coveted 750 hp out of your engine.

Can you cope with such power?

The 2JZ-GTE engine has repeatedly proven that it is capable of squeezing out more than 2000 hp. This will require a turbine larger than 64mm, however, this is not as difficult as it might seem. Start with a 72mm turbo and consider installing forged pistons and connecting rods, as well as stronger main bearing caps. Wider head studs will prevent the cylinder head from lifting off the block. In addition, we advise you to pay attention to 2000cc injectors and a couple of fuel pumps. However, it all depends on how crazy your idea is.

About the limitations of Japanese 2JZ-GTE engines

The 2JZ-GTE engines installed in American cars have a power of 320 hp. and 427 Nm of torque. The reason for this modesty is that in 1989 the Japanese manufacturers decided to end the costly power war by limiting the power of production cars to 276 hp. At least it's documented. Since then, the agreement has been violated several times. In addition, the 2JZ-GTE engine had enormous power potential. For a country in which the maximum permitted speed is 100 km/h, this agreement was quite logical, but for American buyers it was wildness, because they were accustomed to the fact that their grandfather’s wreck goes faster than a good sports car from the 90s. Thus, the manufacturers made sure to squeeze 400 hp out of the 2JZ-GTE. was possible literally through the slightest modifications.

The Toyota 2JZ-GTE engine produces 320 hp. thanks to a pair of Hitachi turbines installed in series. Unlike a parallel twin-turbo design, where two identical turbines blow the same amount of air at the same time, the sequential design is designed so that only one turbine starts working, and then, at higher speeds, the second one takes over.

Typically this design uses two turbines of different sizes, but this engine uses two identical ones. The Toyota Supra was one of the first cars to prove that sequential turbocharging has a place in the tuning world. At 1800 rpm the first turbine turns on. Then, put the pedal to the metal, let the ECU and boost regulator do their work, and by 4000 rpm the second turbo will kick in.

A short tour of spare parts for 2JZ-GRE

Brian Crower camshaft

These camshafts will allow you to squeeze a lot more power out of your 2JZ-GTE. The company produces a wide range of camshafts, among which there are parts for both calm drivers and reckless racers.

AEM Infinity Custom ECU

The Supra's cast iron engine block is certainly quite strong, but without proper tuning it can simply explode and shatter into pieces. The AEM Infinity kit is designed specifically for the Supra engine and allows you to control everything that happens inside the engine.

Turbocharging GReddy

The stock 2JZ-GTE turbos are unlikely to suit you. If you want serious power, pay attention to the GReddy kits, which contain all the necessary parts, such as the pressure regulator, exhaust manifold and the turbine itself. This kit will seriously improve the performance of your car.

The 2JZ-FSE engine represents the latest link in the development line of JZ engines for Toyota cars. The model was taken as the basis for the design and development of this engine, but in addition, it combined the best qualities of other engines in the JZ series. The year 2000 can be considered the start date of active assembly of 2JZ-FSE engines and their installation on Toyota cars.

Features and positive qualities

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline!

It would be fair to say that this model is a modification. For example, from the engine called D4, the 2JZ-FSE inherited direct fuel injection, with an increased displacement and a significantly higher compression ratio, which in the new model was 11.3:1. As for power, it has increased significantly compared to the original 2JZ-GE engine. In addition, fuel consumption has significantly decreased, and the environmental friendliness of this model has also increased due to the fact that the amount of harmful emissions into the atmosphere has decreased. Regarding the harmful emissions of the 2JZ-FSE model, it is necessary to note the competent approach of the design engineers, who implemented this in innovative direct injection technology without loss of power, which was not the case in previous models. The high power of 217 hp undoubtedly allowed the consumer to experience real drive and an instant increase in speed, which is supported by a high torque of 294 Nm.

Disadvantages of the Toyota 2JZ-FSE engine

2JZ-FSE Toyota Crown

Unfortunately, nothing is perfect. The 2JZ-FSE engine model is no exception; problems were observed during its operation. Among the main problems observed were the following:

• Vibrations in the engine;
• After some time of operation, problems arose with “idling”;
• Gas delay, which is especially noticeable at start.

This is evidenced not only by the official recognition of the developers, but also by numerous reviews and complaints from consumers. Other shortcomings, according to consumers, include high gas consumption and slight jerking of the car at low speeds.

As for the shortcomings of this engine, the manufacturer corrected most of them, offering its customers free maintenance. The remaining shortcomings are either insignificant or can be easily resolved by the owner during operation.

Specifications

The manufacturer has officially announced the following technical characteristics of the 2JZ-FSE engine.

Design	6-cylinder engine. Its peculiarity is that all the cylinders are located in a row.
Volume	3 l. (2997)
Power	217 hp
Torque	294 N*m
Compression ratio	11.3:1
Valves	VVT-i, DOHC 24V
Injection system	Direct D-4
Ignition system	Distributor/DIS-3
Resource	designed for a mileage of 1 million km without major repairs

The VVT-i system is a custom development of Toyota, which is classified as an intelligent fuel injection system. The big advantage of this system is the high speed at low thrust. The internal valves are designed so that their opening/closing system is beneficial to the overall performance of the engine. The DOHC system allows the use of more valves per cylinder. In turn, this allows you to get an increase in speed and more power. The disadvantage of such a system is its high cost, which is caused by the large number of parts.
