i'm going to change my nubira 1997 engine, i have some choices:
1- buying a nubira engine : 1600 - 1800 cc
2- buying a nubira engine : 2000cc
3- buying another motor brand ( Opel ), but i'm note sure what type or model will be fit to the nubira, the work shop told me about Opel Omega motor can be used in replacing the nubira motor, ( is it correct )
i need your Help
