I have a Mazda b2200 4cyl which is locked up. The engine has a carburetor with 5 speed. I want to change the motor but 2200 engines are hard to find and when i did find them they are just too expensive. I was told that a ford ranger engine will fit the truck. Is this true? Will i have to exchange out anything else like transmission, or anything that will cost me more than just buying a mazda engine? Please help.
