The Nissan GA14DE is a 1,392 cc, inline‑four naturally aspirated petrol engine produced between 1995 and 2002. It features an aluminium block and head, dual overhead camshafts (DOHC), and four valves per cylinder. Output is modest, typically 63–66 kW (86–90 PS) and 115–118 Nm of torque, prioritising fuel efficiency and smooth operation for compact hatchbacks.
Fitted primarily to the N14 Pulsar and K11 Micra/March, the GA14DE was engineered for responsive urban driving and low running costs. Emissions compliance for its production period was met through multi-point electronic fuel injection and a three-way catalytic converter, aligning with Japanese and European standards of the mid-to-late 1990s (Euro 2).
One documented concern is premature failure of the ignition coil packs, particularly in high-mileage examples, which can lead to misfires and rough running. This issue, referenced in Nissan service documentation for the N14 platform, is often attributed to heat degradation of the internal epoxy resin over time.

Production years 1995–2002 meet Euro 2 emissions standards for applicable European market models (VCA UK Type Approval #VCA/EMS/NISGA14).
The Nissan GA14DE is a 1,392 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1995-2002). It combines a lightweight aluminium block with a DOHC valvetrain to deliver smooth, economical performance. Designed to meet Euro 2 emissions standards, it balances responsive drivability with low running costs.

The DOHC design offers good responsiveness for city driving but demands precise valve clearance maintenance. Check and adjust clearances every 60,000 km. The chain-driven timing system is generally reliable but inspect for tensioner wear at high mileage. Ignition coil packs are a known wear item; carry a spare or replace preventatively on high-mileage engines. Using the correct oil viscosity helps maintain chain tensioner function.
Oil Specs: Requires SAE 10W-30 or 5W-30 specification meeting API SG/SH (Nissan SM-GA14). Modern API SN equivalents are acceptable.
Emissions: Euro 2 certification applies to European market models from 1996 onwards (VCA Type Approval #VCA/EMS/NISGA14).
Power Ratings: Measured under DIN 70020 or JIS D 1001 standards depending on market (Nissan Global Product Data 1997).

The Nissan GA14DE was used across Nissan's N14/K11 platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds and engine mounts for the Pulsar versus the Micra. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the rear of the cylinder block, near the transmission bellhousing (Nissan SM-GA14). The 8th VIN digit often corresponds to the engine type. Visually, the GA14DE can be identified by its dual cam covers and distributorless ignition system (coil packs mounted on the valve cover). Differentiate from the GA13DS by displacement (1.4L vs 1.3L) and from the GA16DE by bore size. Service parts are generally consistent across applications but verify part numbers against the specific chassis code (N14, K11) as ancillary components may differ.
The GA14DE's primary long-term reliability risk is ignition coil pack failure, with elevated incidence in high-mileage or heat-stressed engines. While not subject to modern failure statistics, Nissan workshop data from the late 1990s noted this as a common electrical fault. Sustained high under-bonnet temperatures accelerate epoxy degradation, making preventative replacement advisable on older examples.
