Toyota 2UR-GSE and 2UR-FSE engines
Content
The 2UR-GSE engine took its place in the market in 2008. It was originally intended for powerful rear-wheel drive cars and jeeps. A Yamaha cylinder head is installed on a traditional aluminum block. Conventional metal valves have been replaced with titanium ones. The main changes compared to its predecessors will be discussed in more detail in this article.
The history of the appearance of the 2UR-GSE engine
The replacement of the UZ series engines, which were equipped with the top rear-wheel drive cars of the Japanese manufacturer, began in 2006 with the advent of the 1UR-FSE engine. The improvement of this model led to the "birth" of the 2UR-GSE power unit.
A powerful 5-liter gasoline engine was created for installation on Lexus cars of various modifications. The layout (V8), an aluminum alloy block and 32 valves in the cylinder head remained from its predecessors. The material of the valves and the developer of the cylinder head were reminded earlier.
It is necessary to focus on the main differences between the 2UR-GSE motor:
- the cylinder block is reinforced;
- combustion chambers got a new shape;
- received changes to the connecting rods and pistons;
- installed a more efficient oil pump;
- changes have been made to the fuel supply system.
With all this, the engine does not belong to the high-speed line. The 8-speed automatic transmission played the main role here.
For a number of objective reasons, the 2UR-FSE engine has become somewhat less widespread. Just from 2008 to the present, it has been installed on 2 car models - Lexus LS 600h and Lexus LS 600h L. Its main difference from 2UR-GSE is that it is additionally equipped with electric motors. This made it possible to significantly increase the power - up to 439 hp. Otherwise, it is similar in parameters to the 2UR-GSE. Table characteristics clearly show this.
Speaking about the creation of engines for these models, it must be emphasized that the 2UR-GSE engine has found wide application in the following vehicles:
- Lexus IS-F from 2008 to 2014;
- Lexus RG-F from 2014 to present;
- Lexus GS-F с 2015;
- Lexus LC 500 с 2016 г.
In other words, we can safely say that for almost 10 years this engine has been faithfully serving a person. According to many testers, the 2UR-GSE engine is the most powerful Lexus engine.

Concluding the review of the 2UR-GSE engine, it should be noted that most of the nodes have become new or have received changes during processing. These include:
- pistons and piston rings;
- crankshaft;
- connecting rods;
- valve stem seals;
- intake manifold and throttle body.
In addition to those listed, the engine has a number of upgraded elements.
Maintainability
Questions of the possibility of repair of our driver are concerned in the first place. Even when purchasing a completely new car, a question will be asked about its maintainability. And a specific clarification about the engine.
According to Japanese guidelines, the engine is disposable, that is, it cannot be overhauled. Considering that we live and use this motor outside of Japan, our craftsmen managed to prove the opposite.
The overhaul of the cylinder block and its cylinder head was successfully mastered. All attachments in the event of a malfunction are simply replaced with new ones. The block itself is restored by the cylinder sleeve method. This is preceded by a thorough diagnosis of the entire element. The condition of the crankshaft beds is checked, the development of all surfaces, especially those subject to friction, the absence of microcracks. And only after that a decision is made to sleeve or bore the block to the required repair size.
Cylinder head repair includes such operations as checking for microcracks, the absence of deformation due to overheating, grinding and pressure testing. At the same time, valve stem seals, all seals and gaskets are replaced. Each element of the cylinder head is carefully checked and, if necessary, replaced with a new one.
One conclusion can be drawn - all engines of the 2UR series are maintainable.
For your information. There is evidence that after a major overhaul, the engine calmly nurses 150-200 thousand km.
Engine Reliability
The 2UR-GSE engine, according to many owners, is worthy of all respect. Of particular admiration are a number of improvements that have significantly increased the reliability of the motor. First of all, a high-performance oil pump is mentioned with a kind word. Its flawless work is noted even with strong side rolls. The oil cooler did not go unnoticed. Now there are no issues with oil cooling.
All drivers pay attention to changes in the fuel supply system. In their opinion, she does not cause any complaints in her work.
Thus, according to all car owners, the 2UR-GSE engine has proven to be a fairly reliable unit with proper care for it.
Speaking of trouble-free operation, one cannot ignore the trouble that occurs in the engine. This is a problem with the cooling system. The pump is perhaps the only weak point of this motor. No, it does not break, but over time, its drive begins to leak. This picture is observed after 100 thousand km. car mileage. It is possible to determine the malfunction only by lowering the coolant level.
Extending engine life
The service life of the engine is extended in various ways. The main of them will still be timely, and most importantly, proper service. One of the components of the complex of these works is an oil change.
For the 2UR-GSE engine, the manufacturer recommends using genuine Lexus 5W-30 oil. As a replacement, you can use 10W-30. Why as a replacement? Pay attention to the plate. On the bottom line with numbers.
If the engine is operated in a region where winters are very warm, then there are no problems with the choice of oil.
Service times must be strictly adhered to. Moreover, they need to be reduced (within reasonable limits), taking into account the nuances of operating conditions. Replacing all filters and oils ahead of schedule significantly extends the life of the engine. Many car owners who follow these rules assure that there are no problems with the motor even during long-term operation.
Why do you need to know the engine number
After working out its resource, the engine requires a major overhaul. But in this case, the question often arises before the motorist - is it worth doing it? There can be no single answer here. It all depends on the investments that need to be made and the time to restore the unit.
Sometimes it is easier and cheaper to replace the engine with a contract one. When deciding on a replacement, one must not lose sight of such an important point as the mark on the replacement of the engine in the registration documents of the car. However, it is necessary to take into account two important nuances. If the unit is being replaced with a unit of the same type, for example, 2UR-GSE to 2UR-GSE, then it is not necessary to make a mark in the data sheet.
But if the engine models change during the repair, then such a mark is necessary. In the future, it will be needed when registering a car in the event of its sale and for the tax office. In any case, you will have to specify the engine number. Its location is different for each brand of the unit. In 2UR-GSE and 2Ur-FSE, the numbers are stamped on the cylinder block.
Replacement possibility
Many motorists light up with the idea to change the engine in their car. Some are more economical, while others are more powerful. The idea is not new. There are examples of such substitutions. But such intervention sometimes requires very costly material investments.
Therefore, before finally deciding whether to install 2UR-GSE instead of 1UR-FSE, you need to calculate more than once - is it worth doing this? It is quite possible that it may turn out that along with the engine you will have to change the automatic transmission, driveshaft, gearbox with drives, radiator panel, radiator, subframe and even the front suspension. Such cases have been observed in practice.
Therefore, the best thing that can be done if you want to change the engine is to get detailed advice on this issue from specialists from a specialized service station.
For information. With a high-quality swap, the characteristics of the motor can be significantly improved.
Owners about the motor
Positive feedback about the 2UR-GSE motor once again draws attention to the quality of Japanese engine building. Almost all engines of the Toyota Motor Corporation have proven themselves to be reliable and durable power units. With timely and proper maintenance, they do not bring grief to their owners.
Andrey. (About my Lexus) … There is nothing good in the car except for the engine and the music. It is really impossible to go faster than 160 km / h, although the power reserve is still huge ...
Nicole. …2UR-GSE is a real wolf in sheep’s clothing…
Anatoly. … “The 2UR-GSE is a cool engine, they even put it in all racing cars. A good option for a swap ... ".
Vlad. ... "... made a chip tuning to the engine. The power increased, it began to accelerate faster, and I began to go to the gas station less often ... And most importantly, all this without disassembling the engine itself.
Having considered the 2UR-GSE engine, only one conclusion can be drawn - this is a thing! Power and reliability all rolled into one make it desirable on any make of car. And if you add maintainability here, then it will be quite difficult to find equal to this sample.
