Can you put a 1994 geo metro engine in 1992 metro?

While both are Geo Metros, a direct swap isn't guaranteed. You'll need to check the engine codes of both the donor (1994) and recipient (1992) engines. Even if they're the same displacement (like both being 1.0L or 1.3L), there might be subtle differences in mounting points, wiring harnesses, and ancillary components (like the alternator or power steering pump) that could prevent a bolt-on swap.

You'll need to compare these things:

* Engine Code: This is crucial. Look for a code stamped on the engine block itself. Identical codes significantly increase the likelihood of a successful swap.

* Mounting Points: Carefully compare the engine mounts on both engines and the chassis. Even slight differences can cause major headaches.

* Wiring Harness and Sensors: The wiring harness might need to be adapted or swapped entirely. Sensor locations and types could also differ.

* Ancillary Components: As mentioned, the alternator, power steering pump, and other components might not be interchangeable.

* Exhaust System: The exhaust manifold and piping might not line up perfectly.

* Transmission Compatibility: Make sure the transmission from the 1994 model is compatible with the 1992 model's transmission mounting points.

In short, it's *possible*, but not guaranteed to be a simple swap. It could be relatively straightforward if the engine codes are identical and the ancillary components match, but expect some challenges if they don't. A thorough comparison before attempting the swap is essential. You might need to fabricate parts or do some custom wiring.
