This engine is used in performance-oriented Lexus models that focus on handling and agility, such as the Lexus GS F and the Lexus NX F Sport.

Specifications and maintenance of Lexus V8 engines

The specifications of Lexus V8 engines differ depending on their coding. For instance, the 2UR-GSE has a DOHC (Dual Overhead Camshaft) design with aluminum alloy cylinder heads and a bore and stroke measuring 3.5 inches (89 mm) and 3.3 inches (83 mm), respectively. This engine also has a compression ratio of 12.0:1, making it suitable for high-performance vehicles. It features a dual VVT-i (Variable Valve Timing-intelligent) system, allowing for optimal timing of the intake and exhaust valves, resulting in improved efficiency and performance. The 2UR-GSE has a dry sump lubrication system, which is crucial for high-performance engines as it ensures consistent lubrication even under extreme conditions and high G-forces.

On the other hand, the 1LR-GUE engine has an aluminum alloy cylinder block and a bore and stroke measuring 3.54 inches (90 mm) and 3.54 inches (87 mm), respectively. It also has a higher compression ratio of 11.5:1 compared to the 2UR-GSE engine. Additionally, the 1LR-GUE engine features a VVT-iE (Variable Valve Timing-intelligent Electric) system, enhancing the variable valve timing system by utilizing electric actuators for more precise control.

Regardless of the differences in specifications, maintaining the engines is crucial. Here are some maintenance tips:

• Follow the maintenance schedule in the vehicle's manual.
• Use genuine Lexus parts when doing repairs or replacements.
