Toyota 3UR-FE and 3UR-FBE engines
Content
The 3UR-FE engine began to be installed on cars in 2007. It has significant differences from its counterparts (increased volume, difference in the material of manufacture, the presence of 3 catalysts for exhaust purification, etc.). It is produced in two versions - with and without turbocharging. It is currently considered the largest gasoline engine and is produced for installation in heavy jeeps and trucks. Since 2009, the 3UR-FBE engine has been installed on some car models. The most noticeable difference from its counterpart is that, in addition to gasoline, it can run on biofuels, for example, on E85 ethanol.
History of the engine
A weighty alternative to the UZ series engines in 2006 was the UR series of motors. V-shaped aluminum blocks with 8 cylinders opened a new stage in the development of Japanese engine building. A significant increase in power was given to 3UR motors not only by the cylinders, but also by equipping them with new systems for ensuring operability. The timing belt was replaced by a chain.
The stainless steel exhaust manifold allows you to safely install a turbocharger on the engine. By the way, a special division of the automaker performs tuning of many elements of cars (Lexus, Toyota), including their engines.
Thus, the 3UR-FE swap is possible and successfully applied in practice. In 2007, the installation of supercharged engines began on the Toyota Tundra, and in 2008 on the Toyota Sequoia.
Since 2007, 3UR-FE has been installed on Toyota Tundra cars, since 2008 on Toyota Sequoia, Toyota Land Cruiser 200 (USA), Lexus LX 570. Since 2011, it has been registered on Toyota Land Cruiser 200 (Middle East).
Version 3UR-FBE from 2009 to 2014 installed on Toyota Tundra & Sequoia.
Interesting to know. When installing an engine with a supercharger by official dealers, the 3UR-FE swap has a warranty.

The 3UR-FE engine, at the request of the car owner, can be switched to gas. In practice, there is a positive experience of installing HBO of the 4th generation. The 3UR-FBE motor is also capable of running on gas.
Maintainability
It should be noted right away that the 3UR-FE engine cannot be overhauled, that is, it is disposable. But where can you see our car enthusiast who will believe what is said? And he will do it right. Non-repairable engines (at least for us) do not exist. At many specialized service stations, engine overhaul is included in the list of services provided.
Engine repair is not very difficult when attachments (starter, generator, water or fuel pumps ...) fail. All these elements are replaced by workers relatively easily. Big problems arise when it is necessary to repair the cylinder-piston group (CPG).
During long-term operation in motors, natural wear of rubbing parts occurs. First of all, the oil scraper rings of the pistons suffer from this. The result of their wear and coking is increased oil consumption. In this case, disassembling the engine to restore it becomes inevitable.
If the Japanese stop repairing at this stage, or rather, before reaching this stage, then our craftsmen are just starting to restore the engine from it. The block is carefully defective, if necessary, reamed to the required repair dimensions and sleeved. After diagnosing the crankshaft, the block is assembled.
The next stage of the engine overhaul is the restoration of the cylinder heads (cylinder head). In case of overheating, it must be polished. After checking for the absence of microcracks and bending, the cylinder head is assembled and installed on the cylinder block. During assembly, all defective and consumable parts are replaced with new ones.
A few words about reliability
The 3UR-FE engine with a volume of 5,7 liters, subject to the operating rules, has proven itself to be a reliable and durable unit. Direct proof is his resource of work. According to available data, it exceeds 1,3 million km. car mileage.
A special nuance of this motor is its love for "native" oil. And to its quantity. Structurally, the engine is designed so that the oil pump is most distant from the 8th cylinder. In the event of a lack of oil in the lubrication system, oil starvation of the engine occurs. First of all, this is felt by the connecting rod bearing of the crankshaft journal of cylinder 8.
This "pleasure" is easy to avoid if you constantly keep the oil level in the engine lubrication system under control.
Thus, we come to the final conclusion that the 3UR-FE motor is a fairly reliable unit, if you take care of it in a timely manner.
What kind of oil "loves" the engine
For many motorists, the choice of oil is not such an easy task. Synthetic or mineral water? Answering this question unequivocally is not an easy task. It all depends on the operating conditions, including driving style. The manufacturer recommends using synthetic.
Of course, this oil is not cheap. But there will always be confidence in the performance of the engine. Practice shows that experiments with oil do not always end in success. According to the recall of such an "experimenter", he disabled the engine by pouring the recommended 5W-40, but not Toyota, but LIQUI MOLY. At high engine speeds, according to his observation, "... this oil foams ...".
Thus, making the final conclusion about the brand used in the 3UR-FE engine, it is necessary to understand that the oil recommended by the manufacturer should be poured into the lubrication system. And this is Touota 0W-20 or 0W-30. Cost-saving replacements can result in significant costs.
Two important closing points
Along with the issue of overhauling the engine, some car owners are faced with the question of replacing it with another model. With a constructive tolerance for such an operation, this possibility can be realized. Indeed, sometimes, for various reasons, the installation of a contract ICE is much cheaper than a major overhaul.
But in this case, the engine must be registered. Of course, if you plan to use the machine by one owner, then such an operation can be excluded. But in the case of re-registration of the car to a new owner, the documents will have to indicate the number of the installed engine. Its location on all models of Toyota engines is different.
In addition, it must be taken into account that the installation of an engine of greater or lesser power and volume causes a change in the tax rate. Replacing a motor of the same type does not require registration.
One of the necessary operations when repairing an engine is the installation of a timing chain drive. Over time, the chains simply stretch and significant deviations appear in the operation of the motor. Some motorists are trying to replace the timing chain drive on their own.
Replacing a chain drive is not an easy job. But, knowing the order of its execution and at the same time being able to handle the tool, there are no big problems. The main thing is not to rush and do not forget to align the timing marks after replacing the chain. The coincidence of the marks indicates the correct adjustment of the entire mechanism. At the same time, it must be remembered that not only a notch (as in the photo), but also a small protrusion (tide) can be a fixed mark.
Relation to the engine
The 3UR-FE engine evokes positive emotions among the owners. This is eloquently evidenced by their feedback on his work. And they are all positive. Of course, not everyone's engine works flawlessly, but in such cases, motorists do not blame the engine, but their sloppiness (... tried to fill in another oil ..., ... added oil at the wrong time ...).
Real reviews look like this in most cases.
Michael. “... Good motor! On Lexus LX 570 on a run of 728 thousand km. removed the catalysts. The car quietly develops 220 km / h. Mileage is rapidly approaching 900 thousand ... ".
Sergey. "... About the motor - power, reliability, stability, confidence ...".
M. from Vladivostok. “... gorgeous motor! ... ".
G. from Barnaul. “... the most powerful motor! 8 cylinders, 5,7 liters volume, 385 hp (at the moment more - chip tuning has been carried out) ... ".
Making a general conclusion on the 3UR-FE engine, it should be noted that this is one of the most successful options for Japanese engine building. Reliable, with a high operational resource, powerful enough, with the possibility of increasing power by tuning ... The advantages can be listed for a long time. This engine is in high demand among owners of heavy vehicles.

Hi, can you install the 3UR engine on the Mazda van?
