Modifications

In 2011, the manufacturer released an updated version of the 2UZ-FE engine, equipped with an electric throttle valve and a VVT-i variable valve timing system. This made it possible to achieve a power of 288 liters. sec., which is 50 units more than in the old version, and increase the torque to 477 N * m.

2UZ-FE problems

The device has no significant drawbacks, with timely maintenance of the car and the use of high-quality consumables 2UZ-FE does not bring problems to the car enthusiast. However, the engine still has weak points. It:

• tall fuel consumption;
• the need for constant regulation of the thermal clearances of the valves;
• the risk of breakage of the hydraulic tensioner during belt replacement;
• small resource of the water pump and timing belt (needs to be changed every 80 - 000 km).

Where is the engine number

The device number is located at the front, in the collapse of the block.

Tuning 2UZ-FE

One of the easiest methods to increase the power of a 2UZ-FE is to buy and install a compressor from TRD. This will increase the power to 350 hp.

Another way is to use a Walbro pump, forged pistons, new injectors, ARP studs and a 3-inch exhaust. This approach will help develop power up to 400 liters. from.

What models was installed

The 2UZ-FE motor is installed on such car brands as:

• Lexus GX 470;
• Lexus LX 470;
