ranger 2.3 to 2.5 engine swap

[bob]

Can anyone tell me what the difference is between a 1995 2.3 and a 1998 2.5? The wrecking yard says they are not interchangeable. Can anyone tell me what the difference may be, and if it's possible to make the switch? Will I have to change the computer and the wiring harness? Any help would be appreciated

Your 1995 would be OBD 1 and the 98 would be OBD 2... BIG change in wiring and sensors and what not... Technically though, the 2.5 is just a stroked 2.3... Both are great engines if you ask me...
