The Toyota 1NR — FE is a 1,329 cc, inline‑four, naturally aspirated petrol engine produced between 2008 and 2020. It features an aluminium block and head with dual overhead camshafts (DOHC) and 16 valves, designed for fuel efficiency and low emissions in compact vehicles. In standard form, it delivered approximately 74 kW (100 PS), with torque figures around 132 Nm, prioritising urban drivability and refinement over high performance.
Fitted primarily to the XP90/XP130…

Production years 2008–2010 meet Euro 4 standards; 2011–2020 models comply with Euro 5 depending on market .
The Toyota 1NR-FE is a 1,329 cc inline‑four DOHC petrol engine engineered for compact hatchbacks and sedans (2008-2020). It combines VVT-i technology with a lightweight aluminium construction to deliver responsive, economical urban performance. Designed to meet Euro 4/5 standards, it balances low emissions with dependable, low-maintenance operation.

The Toyota 1NR-FE was used across Toyota's XP90/XP130 platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Yaris and Vitz-and from 2012 the critical piston and ring revision, creating a major service parting line. 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 1NR-FE is generally very reliable long-term, especially post-2012 models with the revised pistons. Its simple, chain-driven design with VVT-i has few major failure points. With regular oil changes using the correct specification and timely cooling system maintenance, these engines can easily surpass 250,000 km. Pre-2012 engines may require the piston upgrade to address oil consumption.
The most frequent issue for pre-2012 engines is excessive oil consumption due to piston ring wear. Other common problems include VVT-i actuator rattle, timing chain tensioner wear, and cooling system leaks (water pump, thermostat housing). These are well-documented in Toyota service manuals and bulletins.
The 1NR-FE was used in the Toyota Yaris (XP90, XP130), Vitz (XP100), and Etios (XP150) from 2008 to 2020. It was the standard 1.3L petrol engine for these global compact models, known for its fuel efficiency and low emissions.
Tuning potential is very limited due to its small displacement and high compression ratio. Basic modifications like a cold air intake or free-flow exhaust may yield minor gains. Significant power increases would require forced induction, which is complex and not cost-effective for this engine. It is best suited to its stock, economical configuration.
Fuel economy is excellent. Expect around 5.5-6.5 L/100km (43-51 mpg UK) in mixed driving for a Yaris. Highway cruising can yield 4.5-5.5 L/100km (51-62 mpg UK), making it a very economical choice for city and commuting use. Economy is heavily dependent on driving style and vehicle condition.
Yes. The Toyota 1NR-FE is an interference engine. This means if the timing chain were to fail or jump, the pistons and valves would collide, causing catastrophic internal damage. This makes regular oil changes critical to maintain chain tensioner function.
Toyota specifies SAE 5W-30 oil meeting API SM/SL or ILSAC GF-4/GF-5 standards. For modern use, a high-quality synthetic or semi-synthetic oil meeting API SN or SP standards is recommended to provide optimal protection for the VVT-i system and timing chain, especially under varied driving conditions.
