Honda Civic 1.4 D14Z6 Engine (Fuel Injection)
R12,500.00
The Honda D14 engine is a 1.4-litre (1,396 cc) inline four-cylinder petrol engine belonging to Honda’s highly reliable D-series family. Produced primarily throughout the 1990s and early 2000s for the European, Asian, and South African markets, it was designed as an economical power plant for everyday commuters like the Honda Civic and Honda Jazz/City.
Core Technical Specifications
-
- Configuration: Single Overhead Camshaft (SOHC), 16 valves (4 valves per cylinder).
- Bore & Stroke: 75 mm × 79 mm.
- Displacement: 1,396 cc.
- Power Output: Generally ranges from 75 hp to 90 hp (55 kW to 66 kW) depending on the variant and fuel setup.
- Torque: Typically between 112 Nm and 130 Nm.
- Fuel Delivery: Varies from early dual-carburettors to Honda’s PGM-FI multi-point electronic fuel injection.
Popular Engine Variants
The D14 went through several iterations, easily identifiable by the engine stamp located on the block:
-
- D14A1: An early version featuring a dual-carburettor setup, pushing roughly 90 hp. Commonly found in late ’80s and early ’90s European Civics.
- D14A3 / D14A4: Found heavily in the sixth-generation Civic (EJ9). The A3 variant was restricted to 75 hp via a small throttle body gasket for insurance/tax brackets in Europe, while the unrestricted A4 made 90 hp.
- D14Z1 / D14Z2: Later OBD-2 compliance versions used in facelifted Civic models, delivering improved emissions and smooth performance.
- D14Z6: Used in the seventh-generation Civic, producing 90 hp with a higher 10.4:1 compression ratio.
Tuning and Performance Modding
Because the D14 lacks Honda’s famous VTEC technology out of the box, standard performance is modest. However, the D-series ecosystem makes it popular for budget enthusiasts:
- The “Mini-Me” Swap: Tuners frequently bolt a VTEC cylinder head from a 1.6L engine (like the D16Z6 or D16Y8) onto the 1.4L D14 block. This adds the high-RPM VTEC engagement to the smaller displacement block.
- Intake Manifold Upgrades: Replacing the restrictive, top-mounted vertical throttle body on engines like the D14A3 with a horizontal intake manifold from a D16 engine is a simple way to free up airflow.
- Turbocharging: While stock internals are fragile, a low-boost turbo setup on a healthy D14 block can safely push output to roughly 140 hp.
