QuestionHave a 94 Mazda B300 4X4 with a 3.0 want to know if a 91 roed ranger 3.0 will fit
Answer It's the same engine, but in 94 they changed the software and operating system due to changes in the laws governing such things. You can probably make it work, but you will need to swap most of the sensors and electronics from the 94 to the new engine.
