* 2.3L 4-cylinder: This was a very popular choice.
* 2.9L V6: A more powerful option than the 4-cylinder.
* 3.0L V6: A later addition to the lineup, so some 1992 Rangers might have had this, but it's less common than the 2.9L.
To know for sure which engine is in *a specific* 1992 Ford Ranger, you'll need to check the vehicle's documentation (owner's manual, vehicle identification number (VIN) decoder, etc.) or look for an engine identification plate on the engine itself.
