Second letter or two letters- just the designation of the family. That is, conditional identification principle device motors. By the way, two-digit families of motors appeared in 1987. At first, these were only six-cylinder engines, although subsequently two letters became very common for four-cylinder engines, such as the 2ZZ series.
The so-called suffix designations, that is, those letters that come after the dash, are symbols of the characteristics of the motor, namely the power system, the number of camshafts, the presence of turbocharging, etc.
Z- The presence of a compressor
T- The presence of a turbine
E- Availability of electronic fuel injection system
F- The type of device is a two-shaft cylinder head with a small angle between the intake and exhaust valves. Such motors are more economical, but less powerful.
G- Antipode of the previous letter. In the cylinder head of engines with this letter, the angle of the intake and exhaust valves much bigger. Moreover, such cylinder heads are equipped with systems such as VVTi or VVTLi (variable valve timing and valve lift).
4E-FTE
Toyota Starlet GT
To get started, deciphering the designations: four-cylinder engine fourth generation family E with a volume of 1.3 liters with a slight "collapse" of valves (25 degrees), the presence of a turbine and an electronic fuel injection system. Despite the fact that this engine is installed only on the Starlet - Glanza model, almost all owners of microlighters (Tercel, Paseo) are in love with it. It should be added that there are practically no tuned and reinforced parts for this motor in wide sale now, so those who decide to swap such an engine should be ready for experiments in their garage. But thanks to the presence of supercharging, the first and simplest turbo method of increasing power, namely the boostup, becomes more relevant than ever. With virtually no harm to the engine, you can raise the boost pressure from the standard 0.68 bar to 0.9 using a boost controller, or replace the intake - exhaust, ECU and turbine actuator and enjoy 160-170 forces!
4A-GE
Toyota Corolla Levin
Next we have a four-cylinder twin-shaft naturally aspirated engine with a volume of 1.6 liters. It is probably not an exaggeration to say that it is the most popular of all Toyota engines due to its reliability and high power. The most interesting in terms of modifications is the 4A-GE Black Top, equipped with variable valve timing with four-throttle intake and five valves per cylinder from the Toyota Levin BZR in last body AE 111. Although previous generation Levin in the body of AE 101, this motor had another letter Z in the name, which means the presence of a mechanical supercharger. Despite this, both engines produced approximately the same power (162hp aspirated and 165hp with a compressor). A proven and reliable fact is that the block of this motor is able to withstand 350 horses in a supercharged version at about 8000 rpm and up to 250 in atmospheric, but already at an exorbitant 10,000 rpm. With the search for tuning parts for this engine, there will be absolutely no problems.
2ZZ-GE
Toyota Celica
Perhaps the most controversial motor currently in the Toyota range and controversial, primarily because of the issue of reliability. The point is that this high speed engine with a volume of 1.8 liters with a system of variable valve timing and valve lift built on an aluminum block. As a result, the main advantages of such a motor are low weight and high power (193hp at 8200rpm). At the same time, many owners of the Selick in the back of the ST231 believe that nothing can be done with it in terms of increasing power. However, Greddy has a slightly different view of the potential of the motor. The fact is that the most common way to increase power is to install mechanical compressor low pressure. A kit with everything necessary for installation will cost 90-100k rubles, and self-installation It will take, according to the manual, no more than a couple of days. Moreover, do not forget that it is such a motor that fits quite easily instead of its less powerful twin, under the hood of the Toyota MRS. And because of its affordability (can be purchased for about 100k rubles), this first-level swap is a very common occurrence among American and domestic owners Mrs.
3S-GTE
Toyota Celica GT-Four, Caldina GT-T
2 liter, turbo, 255 hp stock. Basically, that says it all. One of the few turbo engines available from Toyota, the price of which can vary from 50 to 130k rubles. And not only the owners of atmospheric front-wheel drive Selik use this, but everyone and sundry! There are plenty of branded parts at Japanese and American auctions, starting from equal length exhaust manifolds and dynepipes and ending with stroker kits and turbines. Moreover, the standard piston group quite calmly withstands an increase in pressure up to 1.2 bar, which equates to 320-330 forces. Subject to minimal modifications to the intake - exhaust - non-pump - injectors. But it’s very difficult to say about the limits of the motor, the 500 strong line has been crossed for a long time ...
2JZ-GTE
Toyota Supra, Aristo
Everything fades in front of this engine. Reliable, powerful, six-cylinder engine turbocharged. By the number of cars in which they tried to install it, it beats all records. From Toyota Altezza and Honda S2000 to Mazda RX-7 and Nissan 350Z. By the way, for some of these cars, ready-made swap kits are sold, including adapted subframes, gearbox adapters and cardan shafts. Concerning circuit diagram improvements, the process begins with the rejection of two turbines in the standard in favor of one. This step is primarily due to the lack of ready-made proposals and the relatively low potential of the scheme (up to 450-500 forces). But the program of improvements 2JZ with one turbine offered just a huge amount. Only the Americans from SP Engeneering offer several stages of engine modifications from 400 to 1200 horses. We still do not take into account such tuning giants as TMS, JUN, Top Secret, HKS, where you can collect reliable motor almost one and a half thousand forces. The most interesting thing is that the connecting rod and piston group of this engine is so strong that it can withstand without special problems up to 600hp!
1UZ-FE
Toyota Celsior, Crown, Majesta, Aristo
You're probably wondering what a naturally aspirated V8 has to do with the most tuned engines. Everything is simple. This four-liter engine has been where others never dreamed of. Let's go in order. Because of the relatively light aluminum block the weight of such a motor is a stretch, of course, but comparable to 4A-GE !!! This fact is confirmed by some Australian drifter, who competes on AE86, for the 2008 season, he replaced his 4A-GE with a stock 1UZ, adding only a multi-throttle power system. Moreover, Toyota itself, namely its subsidiary S.A.R.D. (Sigma Advanced Research Developments), manufactured based on the Toyota MR2 and this engine car, better known as SARD MC8-R
debuted at the 24 Hours of Le Mans in 1995. Well, in the end, the most reckless project based on 1UZ-FE! HKS DRAG SUPRA
. Six-second dragster with a capacity of 1479 horses. In this project, the motor was equipped with two HKS GT 3540 turbines and at the same time left the standard valves! Here is such an amazing and little-known 1UZ-FE. According to Maxi-Tuning magazine and the ubiquitous Google
If it is interesting, I will continue to write about other well-known engines!
I hope you enjoyed it =)
PS. If "Toyota" made girls, they wouldn't break either =).
Expression " Japanese quality» often evokes associations with cars concern Toyota, including with their power plants. In fairness, it should be noted that not all units produced by this company have successfully established themselves among Russian motorists.
This remark does not apply to motors of the UZ FE series in any way. It does not hurt to recall what domestic drivers liked one of them - the engine of the 1UZ FE model.
"Big Eight"
The first engines of the highest UZ series rolled off the assembly line of the Tahara plant engine building company in 1989. They have been designed specifically to complete heavy models of sports and premium segment. The firstborn of the series - the 1UZ engine - registered under the hood of a new Toyota sedan Celsior. For American and European markets the car received the sonorous name Lexus LS 400.
Subsequently, Toyota put the 1UZ engine on their models for domestic market: Crown, Aristo, Soarer and on 2 Lexus models - SC 400 / GS 400. How to decipher the designation 1UZ FE, which the ancestor had new series? The abbreviation 1UZ with the letters FE means:
- 1 - unit number within the series;
- U- symbol rulers;
- Z - type of fuel - gasoline;
- F - standard power range;
- E- distributed injection with electronic control.
The configuration of the internal combustion engine is dictated by the power required for heavy-duty vehicles. For its implementation, an FE engine with a displacement of 4 liters was required. Large displacement is provided by 8 cylinders arranged in a V-shape with a camber angle of 90 °.
The unit with this configuration turned out to be relatively compact. 5-pin crankshaft with double connecting rod journals is driven by aluminum-silicon pistons having a ratio geometric dimensions close to a square.
The use of aluminum as a material for the cylinder block (BC) made it possible to reduce the mass of the drive to 220 kg. The power of the unit is about 260 horsepower.
Automatic only
The design contains two 16-valve heads with DOHC gas distribution mechanisms, each containing two camshafts with a distributor and an ignition coil on each of them. Timing drive - belt, and only on the intake, and the exhaust shafts are driven from the intake through gears. In the event of a belt break, the phase is lost, but the valves do not suffer, which is a significant advantage.
In 1995, a small modernization was carried out, associated with lightening the ShPG and increasing compression. As a result, some improvement specifications. In addition, instead of distributors, they used completely electronic system ignition with individual coil for each cylinder.
In 1997, the VVT-i system was introduced on the 1UZ FE V8 engine - variable valve timing. From that moment on, 2 versions of the power unit were produced: 1UZ motor drive with VVT-i system and drive 1UZ FE of non VVT-i version, and all of them were aggregated only with automatic transmissions, 5-speed for VVT-i and 4-speed for non VVT-i. Below are some of the passport data of 3 modifications:
Advantages and disadvantages
Few drives can boast such an impeccable reputation as the 1UZ engine. All those almost 20 years that he rolled off the assembly line, the 1UZ motor was produced in the FE version, without undergoing significant changes. Over time, he was replaced by more voluminous UZ engines: 2UZ-FE (4.7 l) and 3UZ-FE (4.3 l).
It should be noted that fuel consumption is within reasonable limits. For mixed cycle it is about 12 liters per hundred, which is comparable to the appetite of the Volga GAZ-31105, which is a representative of approximately the same class as Toyota and Lexus, with significantly less power power unit.
The main advantage of "Uzet" is a huge resource, reaching half a million or more kilometers.
Description of the shortcomings will not take up much space:
- Poor location of the water pump, which makes it difficult to maintain and leads to an increase in the load on the toothed belt, which is also the timing drive. As a result of a broken belt on modifications with VVT (VVT), the valves bend.
- Difficult access to candles.
- The first engines were difficult to maintain distributor ignition.
- It is easy to damage the automatic timing belt tensioner when replacing the belt.
Service
Despite the legendary durability of the unit, it is necessary to monitor it technical condition and timely comply with all regulatory procedures:
- Claimed durability toothed belt is 100 thousand km. In fact, for safety reasons, it is better to replace a little earlier. When installing, pay attention to the coincidence of control marks with reference points.
Before installing the automatic tensioner, it is necessary to check its performance. The pusher should protrude approximately 11 mm (10.5–11.5) beyond the edge of the body.
- Engine oil needs to be changed every 10 thousand kilometers, not forgetting to change oil filter. When choosing a lubricant, follow the recommendations in the service manual vehicle and take into account the degree of engine wear.
- Candles require special attention. Platinum NGK BKR6EP-11 is suitable for a regular UZ, and for UZ FE VVT-i it is advisable to use products with iridium tips, for example, DENSO SK-20R11.
To whom - tuning, and to whom - swap
Thrill-seekers do not always have the power of stock motors. 1UZ engine provides wide opportunities for forcing:
- The most affordable and common option is to install the Eaton M90 compressor as part of a kit. If you add here the "pants" 4-2-1, supplemented by a direct-flow exhaust, with a boost of 0.4 bar, you can remove 330 hp. With.
- 4 hundreds of “horses” will be provided by the installation of a SHPG with forged pistons, injectors from 2JZ-GTE, a 3-inch exhaust, an intercooler and a VEMS control unit. The pressure should be raised to 0.7 bar.
- A higher power increase will be provided by using a Garrett GT40-based turbo kit instead of a compressor, or a self-selected kit, including blow-off, boost controller and VEMS processor. At the output of 1UZ turbo, it is possible to get 450 hp. With.
- Two Garrett VNT25 units form 1UZ twin turbo with a capacity of about 500 "horses".
Many use the 1UZ swap for various domestic cars: Volga, UAZ, Gazelle, GAZ-66 and a number of others. Even the owners Japanese cars such as Toyota Altezza, Toyota Chaser, "Toyota Mark 2", Mitsubishi Pajero install this unit. In addition, it is used on small river boats, makeshift airboats. No wonder the Americans in 1997 developed and certified on the basis of this motor aircraft engine FV2400-2TC for private light aircraft.
Probably no Japanese power unit did not receive such recognition automotive world, like Toyota's Uzet.
Due to its reliable design, unpretentiousness in maintenance, this motor is still in demand by numerous enthusiasts, as well as in various types transport technology, not only automobile, but also air or water.

Reliability, problems and engine repair Toyota 1UZ 4.0 l.
The ancestor of the Toyota UZ family (which later included 2UZ and 3UZ), the 1UZ engine, appeared in 1989 and was intended for top models Toyota and Lexus. This 4-liter engine was intended to replace the old 5V engine and successfully coped with its task, along the way gaining a reputation as one of the most resourceful and reliable Toyota engines.
Cylinder block 1UZ-FE aluminum, camber angle 90°, with pressed-in thin cast iron sleeves. On top are two aluminum cylinder heads, two camshafts each and 4 valves per cylinder. There are no hydraulic lifters, so 1UZ requires periodic valve adjustment.
Since 1995, the engine has been slightly updated, light connecting rods were used (there were 628 grams, now 581 grams) and pistons for a compression ratio of 10.4, and power increased to 260 hp.
Since 1997, 1UZ-FE has received VVTi system on the intake shaft, the intake channels have changed, the diameters of the intake and exhaust valves have increased, the cylinder head gasket, a long two-stage intake manifold ACIS, improved ignition system. Also, the 1UZ-FE VVTi uses new pistons for a compression ratio increased to 10.5, as well as an electronic throttle.
A belt was used in the timing drive, its service life is 100 thousand km. On versions without a variable valve timing system VVTi, when the timing belt breaks, the valves do not bend. Versions with VVTi cannot boast of this.
The release of this power unit continued until 2002, when it was superseded by the 4.3 liter 3UZ-FE.
Problems and disadvantages of Toyota 1UZ 4.0 l engines.
Engine 1 will recognize the case when you have to look for flaws with a magnifying glass. 1UZ-FE does not have any design miscalculations, shortcomings and diseases. All faults found on these power plants associated most often with age, manner of exploitation or irregular maintenance. From low-quality gasoline spark plugs can die quickly, and replacing them is fraught with some difficulties. By itself, 1UZ-FE is extremely reliable and is often called a millionaire by the people. This engine is capable of traveling 500,000 km or more.
Tuning engine Toyota 1UZ-FE
Compressor
The first step towards increasing the power of 1UZ could be to buy a kit compressor based on the Eaton M90. Such options have an intake manifold included, and you also need to buy a fuel regulator. To this, it is desirable to purchase a direct-flow exhaust and 4-2-1 manifolds. At a pressure of 0.4 bar, the 1UZ motor can develop up to 330 hp. It is the most reliable and popular tuning for US.
To get more more power, you need to buy forged pistons for a compression ratio of 8.5, connecting rods, ARP studs, intercooler, injectors from 2JZ-GTE, Walbro 255 lph, 3″ exhaust, VEMS brain and inflate 0.7 bar. This will be enough to get over 400 hp.
1UZ turbo
On the forged pistons of the above configuration, instead of a compressor, you can assemble a turbo knot using a turbo kit based on one Garrett GT40. Or buy the turbine itself, intercooler, weld the manifold. You will also need a wastegate, blow-off, boost controller, oil drain, oil supply, thermal insulation, pipes, clamps, VEMS brains. As a result, 1UZ will show more than 450 hp.
1UZ twin turbo
Something similar can be done on the basis of two Garrett VNT25 turbines. Similar whales are sold and easily installed on a forged piston. This can provide over 500 hp.
In any of these cases, you can use more powerful superchargers, seriously approach the refinement of the engine, increase the boost pressure and remove the maximum possible power.
The extremely reliable “millionaire” from Toyota with the 1UZ-FE marking is not officially one, but it can easily overcome 500 thousand. And car owners often do tuning 1UZ-FE, on which a compressor kit (using the Eaton M90), a turbo kit (Garrett GT40 or two Garrett VNT25 turbines) is installed. Thus, the power of the car can be raised from the standard 256-300 "horses" to 500 and above.
It is no coincidence that this 4-liter engine is installed on top cars Toyota (Crown, Aristo, Celsior, Soarer) and Lexus 400 (GS, LS and SC). Having become the ancestor of a whole family of engines, 1UZ is recognized as one of the most reliable and resource-intensive Toyota power units.
Specifications 1UZ-FE
The engine replaced the old 5V in 1989 and was successfully produced until 2002. It is an 8-cylinder aluminum injector with 4 valves per cylinder, a camber angle of 90 degrees and a compression ratio of up to 10.5. The motor is equipped with a pair of aluminum heads, each with 2 camshafts. Since there are no hydraulic lifters, periodic adjustment of the valves will be required.
In 1995-97, the engine withstands several updates. Up to 581 grams, the weight of the connecting rods is reduced, the pistons are lightened, and the power is increased. The unit receives intake system VVTi, valve diameters have increased, ignition has been improved, an ACIS manifold has been installed, an electronic throttle has been installed.
On the 1UZ-FE power unit, the timing belt is used as a timing drive. Standard term its service is 100 thousand mileage. Interestingly, earlier versions have no special consequences when the belt breaks. Valves bend only in engine versions with installed system VVTi.
Possible problems
This is the case when you can safely buy a 1UZ FE engine without fear for quality. There are no design flaws or flaws in the manufacture. All possible faults can be classified like this:
- motor age;
- service irregularity;
- manner of operation;
- fuel quality (“dead” candles are difficult to replace).
Otherwise, the motor is trouble-free and lasts a long time, so the 1UZ FE used engine (especially a contract one, without internal mileage) is an excellent purchase.
