The Honda ET2 is a 1,196 cc, inline‑four petrol engine produced between 1983 and 1986. It features a single overhead camshaft (SOHC) with 2 valves per cylinder and Honda's twin — choke carburetion system. In standard form it delivered 60 PS, prioritizing simplicity and fuel economy for Honda's compact city cars.
Fitted to the second — generation Honda City, the ET2 was engineered for urban mobility and light commuting. Its character is defined by frugal fuel consumption an…
Production years 1983–1986 meet applicable Japanese emissions standards for its model year and market (Type Approval per Japanese Ministry of Transport 1982 Guidelines).
The Honda ET2 is a 1,196 cc inline‑four petrol engine engineered for compact city cars (1983-1986). It combines SOHC 8-valve architecture with a carburetor to deliver exceptional fuel economy and ultra-reliable, low-stress performance. Designed to meet 1980s Japanese emissions regulations, it prioritizes simplicity and cost-effectiveness.

The Honda ET2 was used exclusively in Honda's second-generation City platform with transverse mounting. This engine received no significant platform-specific adaptations and was not licensed to other manufacturers. All applications are documented in OEM parts catalogues.
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.
The ET2's primary characteristic is its exceptional reliability due to its low-stress, simple design. Honda's internal quality reports from the 1980s noted minimal warranty claims for this engine. Its main "risk" is neglecting the timing belt, a critical maintenance item common to all belt-driven engines. Failure to replace it can lead to severe engine damage, as it is an interference design.
Analysis derived from Honda technical bulletins (1982-1987) and general automotive engineering principles. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the ET2 is renowned for its exceptional long-term reliability. Its simple, low-power design creates minimal stress on components. With basic maintenance—especially timely timing belt changes—it can easily exceed 200,000 km. Its reputation is one of indestructibility for its era.
The most common issues are not failures but maintenance items: timing belt replacement, carburetor cleaning/rebuilding, and distributor/oil seal leaks. Cooling system hoses and the radiator can also fail with age. These are typical for carbureted engines of the 1980s, not unique flaws of the ET2.
The ET2 was used exclusively in the second-generation Honda City (AA chassis, 1983-1986). This was a compact city car designed for the Japanese domestic market, known for its innovative packaging and the ability to carry a Motocompo scooter in its trunk.
Limited potential. Basic maintenance and a clean carburetor will restore its original performance. Significant power increases are difficult due to its small displacement, two-valve head, and carbureted fuel system. It is not a common candidate for engine swaps or forced induction.
Excellent for its time. In a lightweight Honda City, real-world fuel economy often exceeded 40 mpg (UK) / 7.1 L/100km on the highway, with city figures around 30-35 mpg (UK) / 9.4-8.1 L/100km. Its design prioritized efficiency, making it one of the most economical engines of the early 1980s.
Yes. Like most Honda engines of this era, the ET2 is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing catastrophic engine damage. This makes adhering to the 80,000 km replacement interval absolutely critical.
Honda recommends a 10W-30 or 5W-30 mineral oil meeting API SF or SG specifications. Regular oil changes (every 5,000-10,000 km) are more important than using expensive synthetic oil for this engine's longevity.
