Engine 2TR-FE
Domestic motorists know the 2TR-FE engine mainly from the Toyota Prado SUV, under the hood of which it has been installed since 2006. On some other models, such as Hilux, the engine has been installed since 2004.
Description
The 2TR-FE is Toyota's largest four-cylinder engine. The exact volume is 2693 cubes, but the row "four" is indicated as 2.7. Unlike the 3RZ-FE engine of the same size, the engine is equipped with a Toyota variable valve timing system, which, in the case of the Land Cruiser Prado 120 and Prado 150, allows you to get 163 hp at the output. at 5200 rpm crankshaft.
The Toyota 2TR-FE engine is equipped with four valves per cylinder, which improves combustion chamber scavenging and works to increase power, because the air flow constantly moves in one direction - from the intake valves to the exhaust. The legendary Toyota reliability is also facilitated by the timing chain drive. 2TR-FE vvt-i is equipped with a distributor injection system.
Geometry and characteristics
Like many other Toyota engines, the diameter of the motor cylinders is equal to the piston stroke. Both parameters in 2TR-FE are 95 mm. The maximum power transmitted to the wheels, depending on the model, varies from 151 to 163 horsepower. The highest output power is obtained from the Prado, whose torque is 246 N.M. The specific power of the 2TR-FE installed on the Land Cruiser Prado 120 is 10.98 kg per 1 horsepower. The compression ratio of the engine is 9.6: 1, these compression ratios make it possible to use 92nd gasoline, but it is better to fill in 95th.

The power characteristics of the 2TR-FE give even a heavy SUV enough agility in city traffic, but on the highway, when you need to overtake from a speed of 120 km, the power may not be enough. Timely oil change is extremely important for any internal combustion engine. The 2TR-FE engine is designed for 5w30 synthetic oil, which should be changed every 10 km. For 2TR-FE, an oil consumption of 300 ml per 1 km is considered the norm. At high engine speeds, the oil goes to waste. The thermal gap in the engine is 000 mm.
With proper operation, the engine resource before boring is about 500 - 600 thousand km, but with a run of 250 km, replacement of the rings will already be required. That is, by the time the cylinders are bored to the first repair size, the rings are replaced at least once.
On many cars, with a run of 120 km, the front crankshaft oil seal begins to leak. The engine block is cast from cast iron and does not have a nickel coating, which increases the resource and trouble-free operation of this engine.
The 2TR-FE engine was installed on such models as:
- Land Cruiser Prado 120, 150;
- Tacoma;
- Fortuners;
- Hilux, Hilux Surf;
- 4-Runner;
- Innova;
- Hi-Ace.
Engine tuning
Tuning SUVs, namely the installation of larger wheels on them, as well as equipment that increases the weight of the car, makes it difficult for the 2TR-FE engine to pull all this mass. Some of the owners install mechanical superchargers (compressors) on the unit, which increase power and torque. Due to the initially low compression ratio, the installation of the compressor will not require intervention in the block and cylinder head 2TR-FE.
The bottom of the 2TR-FE piston is not flat, it has valve grooves, which also reduce the risk of the valve meeting the piston, even if the chain breaks, but with proper operation, the timing chain on the motor serves until the engine is overhauled.
