Engine Opel Z10XEP

The 1.0-liter Opel Z10XEP or LJ4 engine was produced from 2003 to 2009 in Austria and was installed only on the third and fourth generations of the Corsa model or the very first Agila. The motor was distinguished by the presence of a proprietary system for changing the geometry of the Twinport intake tract.

The Z10 series also includes engines: Z10XE, Z12XE, Z12XEP, Z14XE and Z14XEP.

Differs in the presence of a proprietary system for changing the geometry of the intake tract Twinport, which closes half of the intake valves, which is why the engine pulls better at the bottom. At high rpm, the flaps open and the motor runs at full speed. Controls the motor of the Bosch ME7.6.1 / Bosch ME7.6.2 ECU.

The engine was installed on:

  • Opel Agila A (H00) in 2003 – 2007;
  • Opel Corsa C (X01) in 2003 – 2006;
  • Opel Corsa D (S07) in 2006 – 2009.
