The Lexus 2UR — GSE is a 4,969 cc, naturally aspirated V8 petrol engine produced between 2007 and 2020. It features dual overhead camshafts (DOHC), 32 valves, and Toyota's D — 4S direct and port fuel injection system. This architecture delivers a broad powerband, with outputs ranging from 351 kW (477 PS) to 389 kW (530 PS) and torque figures between 510–553 Nm.
Fitted to flagship models such as the IS F, RC F, and GS F, the 2UR — GSE was engineered for high — revving performance and l…
Production years 2007–2010 meet Euro 4 standards; 2011–2020 models meet Euro 5 compliance depending on market .
The Lexus 2UR-GSE is a 4,969 cc V8 naturally aspirated petrol engine engineered for high-performance sedans and coupes (2007-2020). It combines D-4S direct and port injection with dual VVT-i to deliver a linear, high-revving powerband. Designed to meet Euro 4 and Euro 5 standards, it balances exhilarating performance with refined operation.

The Lexus 2UR-GSE was used across Lexus's flagship performance platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the IS F and unique exhaust manifolds for the RC F-and from 2014 the GS F adopted a higher-output variant with forged internals, creating subtle performance differences. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the 2UR-GSE is widely regarded as an exceptionally reliable and robust engine. Its over-engineered design and use of high-quality materials allow it to easily surpass 300,000 km with proper maintenance. The primary concerns are ancillary components like the water pump or alternator, not the core engine itself.
The most common issues are ancillary: water pump leaks, alternator failure, and for very early IS F models, valvetrain noise. Oil consumption can become noticeable at very high mileages. Carbon buildup is minimal thanks to the D-4S injection system, unlike many direct-injection engines.
The 2UR-GSE powered Lexus's 'F' performance models: the IS F (2007-2014), the RC F (2014-2020), and the GS F (2015-2020). It was not used in any Toyota-badged vehicles for the consumer market, remaining exclusive to Lexus F performance cars.
Yes, it has good tuning potential. Simple ECU remaps can yield 20-30 kW gains. More extensive modifications like headers, high-flow cats, and pulleys can push outputs over 440 kW. The bottom end is very strong, but forced induction requires significant internal upgrades and is not common for this engine.
Fuel economy is typical for a large, naturally aspirated V8. Expect 14-16 L/100km in combined driving for the IS F, and 13-15 L/100km for the more aerodynamic RC F and GS F. Highway cruising can see figures around 10-11 L/100km, while city driving will be significantly higher.
Yes. Like virtually all modern DOHC engines, the 2UR-GSE is an interference design. If the timing chain were to fail (an extremely rare event), the pistons would collide with the valves, causing catastrophic engine damage. Regular oil changes are the best preventative maintenance.
Lexus/Toyota recommends 5W-40 synthetic oil meeting API SN or ILSAC GF-5 specifications. Using a high-quality 5W-40 oil and changing it every 10,000 km (or annually) is crucial for maintaining the engine's health, especially for the valvetrain and turbocharger (if applicable).
