The Lexus 2GR — FSE is a 3,456 cc, V6 direct — injection petrol engine produced between 2007 and 2014. It features Toyota's D — 4S dual injection system combining port and direct fuel injection, along with dual overhead camshafts and variable valve timing (VVT — i). This architecture delivers strong mid — range torque for responsive acceleration while maintaining improved fuel efficiency over conventional port — injected designs.
Fitted to models including the IS 250, GS 2…
Production years 2007–2010 meet Euro 4 standards; 2011–2014 models may have Euro 5 compliance depending on market .
The Lexus 2GR-FSE is a 3,456 cc V6 naturally aspirated petrol engine engineered for mid-size luxury vehicles (2007-2014). It combines direct fuel injection with port fuel injection (D-4S) to deliver balanced power delivery and reduced intake valve deposits. Designed to meet Euro 4 and market-specific Euro 5 standards, it balances high-output performance with improved thermal efficiency.

The Lexus 2GR-FSE was used across Lexus's IS/GS/LS/RX platforms with longitudinal mounting and licensed to Toyota for transverse applications in European markets. This engine received platform-specific adaptations—revised intake runners in the IS 250 and enhanced cooling passages in the LS 460—and from 2011 the facelifted GS 250 adopted the 2GR-FSE with updated ECU calibration for Euro 5 compliance, creating interchange limits. Partnerships allowed Toyota's GR-FSE-based engines to leverage identical injection systems. 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
The 2GR-FSE is mechanically robust with strong internals, but early models (2007–2010) suffer from significant intake valve carbon buildup due to direct injection. Later revisions improved ECU strategies, and well-maintained examples with regular induction cleaning and synthetic 5W-30 oil can achieve high mileage reliably. Neglect increases risk of misfires and power loss.
The biggest issues are intake valve carbon buildup, VVT-i actuator failure, throttle body carbon accumulation, and crankshaft position sensor degradation. These are all documented in Lexus Technical Service Bulletins, particularly SIB 0128-11 for carbon management. Regular maintenance mitigates these risks significantly.
This 3.5L V6 was used in the Lexus IS 250 (2007–2013), GS 250 (2011–2014), LS 460 (2007–2012), and RX 350 (2007–2014). It was also licensed to Toyota for the Altezza AS300 (2007–2010). In Europe, these models met Euro 4 standards until 2011, with later versions upgraded to Euro 5.
Aftermarket ECU tuning is common on the 2GR-FSE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for its class. In the IS 250, expect 10.5–11.5 L/100km (city), 7.0–7.5 L/100km (highway), or roughly 35–40 mpg UK combined. Larger vehicles like the RX 350 consume closer to 12.0 L/100km city and 8.5 L/100km highway. Economy depends heavily on driving style and carbon buildup severity.
Yes. The 2GR-FSE is an interference engine. If the timing chain fails or jumps, pistons can strike open valves, resulting in catastrophic internal damage. Chain tensioner condition and regular inspections are critical for long-term reliability.
Lexus specifies Toyota Genuine Oil 5W-30 meeting API SN / ILSAC GF-5 standards. Change intervals should be every 10,000 km or annually, whichever comes first, to maintain lubrication integrity and minimize sludge formation that affects VVT-i and intake valve cleanliness.
