The Nissan E16S is a 1,597 cc, inline‑four naturally aspirated petrol engine produced between 1985 and 1990. It features a cast iron block, aluminum head, single overhead camshaft (SOHC), and electronic fuel injection (ECCS). This design prioritized improved emissions control and fuel efficiency over its carbureted predecessors, delivering outputs of 63–72 kW (86–98 PS).

Production years 1985–1990 meet applicable emissions standards for their respective model years and markets (VCA UK Type Approval data for relevant chassis codes).
The Nissan E16S is a 1,597 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (1985-1990). It combines a simple SOHC valvetrain with electronic fuel injection (ECCS) to deliver reliable, economical performance with improved emissions. Designed to meet the pre‑Euro emissions standards of its production era, it prioritizes durability and serviceability.

The Nissan E16S was used across Nissan's B12/N13 platforms with transverse mounting. This engine received minor ECU and emissions adaptations for different global markets. 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.
The E16S's primary reliability risk is ECCS ignition module failure, with elevated incidence in hot/humid climates or with poor electrical grounding. Nissan service data indicates ignition faults were a common cause for workshop visits, while UK DVSA records note fuel system issues in neglected vehicles. Ensuring a dry, clean ECU environment and solid electrical connections make regular inspection critical.
Analysis derived from Nissan technical bulletins (1985-1990) and UK DVSA failure statistics (historical data). 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 E16S is generally reliable long-term if basic maintenance is observed. Its simple SOHC design and non-interference layout are robust. Key to longevity is regular oil changes, timely valve adjustments, and addressing the known ECCS ignition module weakness. Many examples have surpassed 250,000 km with proper care.
The most common issues are ECCS ignition module failure causing no-start or misfires, throttle position sensor (TPS) malfunctions leading to drivability problems, valve clearance needing adjustment, and oil leaks from the valve cover gasket. These are well-documented in Nissan service manuals.
The E16S was primarily used in the Nissan Sunny (B12: 1985-1990) and Nissan Pulsar (N13: 1986-1990) across various global markets. It was typically fitted to higher-spec variants like the Super Saloon and Milano, replacing the carbureted E16 in these trims.
Modest power gains are possible. Common upgrades include a performance air filter, free-flow exhaust, and ensuring the ECCS system is in perfect working order. Significant power increases are limited by the SOHC 8-valve head design. Tuning is popular for its simplicity and low cost, focusing on drivability rather than high horsepower.
Fuel economy is very good for its era. In a Nissan Sunny B12, expect around 7.5–8.0 L/100km (35–38 mpg UK) combined in real-world driving. Highway cruising can yield figures closer to 6.0–6.5 L/100km (43–47 mpg UK), depending on condition and driving style.
No. The Nissan E16S is a non-interference engine. This means that if the timing chain were to break or jump, the pistons will not contact the valves. This design significantly reduces the risk of catastrophic engine damage from timing component failure.
Nissan recommends a high-quality mineral or semi-synthetic SAE 10W-40 engine oil. Regular oil and filter changes every 10,000 km (or 6 months) are crucial for engine longevity, especially to protect the timing chain tensioner system from sludge buildup.
