Opel X14XE

Opel X14XEThe Opel X14XE is a 1.4 l (1,389 cc, 84.76 cu-in) straight-four 4-stroke natural aspirated gasoline small-displacement engine developed by Opel, at the time a subsidiary of General Motors. The engine was manufactured from 1994 to 2000.

The X14XE uses a cast-iron engine block with a cast-iron crankshaft and aluminum head with dual belt-driven overhead camshafts (DOHC) and four valves per cylinder (16 valves in total). The engine is equipped with Multec-S ECU (Euro II).

Bore and stroke are 77.6 mm (3.06 in) and 73.4 mm (2.89 in), respectively. The compression ratio rating is 10.5:1. The X14XE engine produces 90 PS (66 kW; 88 HP) at 6,000 rpm of maximum horsepower and 125 N·m (12.7 kg·m, 92.1 ft·lb) at 4,000 rpm of peak torque.

The breakdown of the engine code is as follows:

  • X – Euro 2 engine
  • 14 – 1.4 Liter displacement
  • X – Comression ratio from 10 to 11.5:1
  • E – Multi Point Fuel Injection system

  1. This information is misleading as most if not all info relates to the later generation z14xe which is chain driven and x14xe being belt driven.

    • The z14xe engine, as well as the x14xe, has a timing belt. Apparently, you mean z14xep, it has a chain drive. The z14xe and x14xe engines basically are the same engine.

      • Hello there, your opening segment says X14XE :
        “The X14XE uses a cast-iron engine block with a cast-iron crankshaft and aluminum head with dual chain-driven overhead camshafts (DOHC) and four” etc….
        Then at Cylinder head it says :
        “The cylinder head is made of an aluminum alloy. The X14XE engine has belt-driven dual overhead camshafts”.
        Is there a belt and chains on my Astra G 1.4 16 valve manual petrol (KG03AFA)?
        Is it an interference engine please?
        Regards and thanks, Tony.
