Realistically, it might fit into other very small, lightweight cars from the same era, like some subcompacts or even some really tiny kei cars, but the effort involved would far outweigh the benefits. The engine's low power would leave the car underpowered and potentially dangerous.
You'd have to consider factors like:
* Engine bay dimensions: You need enough space for the engine, transmission, and associated components.
* Mounting points: You'd need to fabricate new mounting points.
* Drivetrain compatibility: The transmission needs to be compatible with the differential and axles of the recipient vehicle.
* Wiring harness and ECU: Adapting the electrical system would be a significant undertaking.
In short, while it *might* physically fit into some similarly tiny vehicles, it's generally not a worthwhile project. The tiny engine's weak power output would make it a frustrating and underpowered vehicle, and the modifications required would be complex and costly.
