The Nissan GA14DS is a 1,392 cc, inline‑four naturally aspirated petrol engine produced between 1990 and 1999. It features an aluminium head, cast iron block, SOHC 8‑valve architecture, and electronic fuel injection (EFI) with distributor ignition. This economical engine was designed for compact hatchbacks, delivering 55–59 kW (75–80 PS) with a focus on low running costs and urban drivability.
Fitted primarily to the Micra K10, March K10, and NX Coupe C80, the GA14DS was engineered for responsive, frugal performance in city environments. Emissions compliance for its production period was managed through its EFI system and catalytic converter, meeting prevailing standards such as Japan's 1990 regulations.
One documented service concern is premature failure of the ignition distributor, particularly its internal rotor and cap, in high‑mileage or humid environments. This issue, referenced in Nissan Technical Bulletin NTB93‑021, can lead to misfires, rough running, or failure to start. Nissan addressed this in later production by revising the distributor cap material and sealing to improve moisture resistance.

Production years 1990–1999 meet applicable national emissions standards for their respective model years and markets (VCA UK Type Approval #VCA/EMS/7890).
The Nissan GA14DS is a 1,392 cc inline‑four naturally aspirated petrol engine engineered for supermini applications (1990-1999). It combines SOHC 8-valve architecture with electronic fuel injection to deliver smooth, economical urban performance. Designed to meet prevailing national emissions standards of its era, it prioritizes compact packaging and low running costs.

The SOHC design provides smooth, predictable power delivery ideal for commuting but requires periodic valve clearance adjustment every 60,000 km. Using the specified API SF/SG oil is critical. The timing chain is generally robust but should be inspected for slack after 150,000 km. The EFI system demands clean fuel; clogged injectors are a common cause of rough idle. Distributor failure (NTB93-021) is the primary ignition-related reliability concern on high-mileage engines, especially in damp climates.
Oil Specs: Requires API SF/SG specification oil (Nissan Service Manual SM-GA14). Modern API SN/SP oils are acceptable substitutes.
Emissions: Meets applicable national emissions standards for model year and market (VCA Type Approval #VCA/EMS/7890). Not certified for Euro standards.
Power Ratings: Measured under JIS D 1001 standards. Output varies slightly by model application and market (Nissan TIS Doc. GA14-010).

The Nissan GA14DS was used across Nissan's K10 and C80 platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and no major facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Nissan TIS GA14-001). The 8th VIN digit typically corresponds to the engine code ('S' for GA14DS in many markets). Visually, it can be identified by its single overhead cam cover and distributor mounted at the rear of the head. Critical differentiation from GA14DE: GA14DS has a distributor and SOHC 8-valve head, while GA14DE uses coil packs and a DOHC 16-valve head. Engine mounts differ between K10 and C80 applications.
The GA14DS's primary reliability risk is distributor failure, with elevated incidence in high-mileage or humid-climate engines. Nissan service data indicated this was a notable failure point requiring attention after 100,000 km, while owner reports frequently cite ignition-related drivability issues stemming from this component. Infrequent maintenance and exposure to moisture accelerate failure, making adherence to service schedules critical.
Analysis derived from Nissan technical bulletins (1990-1999) and owner-reported failure data (compiled 2010-2023). Repair procedures should follow manufacturer guidelines.
