Is the k series engine in a 1991 1.1s with carburetor be the same block and head as a 1997 1.1 injection model?

The K series engine in a 1991 1.1S with a carburetor and the 1997 1.1 injection model may share the same basic block design, but there are likely differences in the head, fuel delivery system, and other components due to the transition from carburetion to fuel injection. The injection model may have modifications to accommodate the fuel injection system, such as different intake and exhaust configurations. Therefore, while they may be similar, they are not necessarily interchangeable without modifications. Always consult specific service manuals or engine specifications for precise compatibility information.
