Does the 1990 Ford Laser GL have same engine as 1992 GL?

Not necessarily. While both the 1990 and 1992 Ford Laser GLs likely shared some engine options, they weren't guaranteed to have the *same* engine. Ford may have made changes to engine offerings or specifications between model years. To know for sure, you'd need to check the specifications for each individual car (found in the owner's manual or perhaps a vehicle history report).
