Would the engine of a 93 ranger bolt behind a transmission manual shift of a 90 madza B2200 both having 4-cylinder engines?

NO!! The Mazda engine and Ford engine are totally different period.Mazda was still strickly Mazda until 1993. It was not until 1994 when Mazda and ford became the same on engine and tranmission similarities.You need a Mazda engine for your Mazda transmission.Note the 1986-1993 Mazda bseries trucks are all Mazda manufactured.Ford is not interchangeable with these models period.
