Ford Festiva B1 1138cc Engine Help me.

[cyptek]

Hello. I have a 1992 model Ford Festival car made in Japan. Its engine is Mazda B1 1138cc. I need technical information for engine maintenance. Parts of the 1300cc model are available everywhere. Since Kia Prides have 1300cc, their parts can also be used. Is the Cylinder head of the 1138cc and 1300cc engines the same? I think there are differences in engine block, piston diameter and crank. Can someone with detailed technical data of both engines help?

Sorry you haven't had any replies yet. I don't have the information but perhaps if you find heads for both on the Internet even if out of stock or discontinued you can compare part numbers and photos.
