The A16LET engine is equipped with a K03 turbocharger which can provide adequate air mass for 34+ Kgm and 240+ Hp.
However the engine’s internal parts cannot withstand this level of stress.
In order to take advantage of the maximum reliable turbochargers air mass provision and to perform the maximum possible power it is essential to replace the engine’s internal parts to ensure the engine’s reliability.
Z16LET engine was throttled by the Euro 5 environmental requirements and was called A16LET, actually, this is the difference between A16LET and Z16LET, which comply with the Euro-4 requirements.
In 2012, Opel has replaced it with the A16XHT engine, very modern, more torque, and in general, a better engine.
