Re: different Mazda/Ford Engines
in rangers and b series after 1994 they are all ford engines and Mazda transmissions. before 1994 in Mazda b series they are Mazda engines. and around 1990 ford switched from Mitsubishi transmissions to Mazda transmissions
while ford engines have always been in the ranger.
now if you are looking for reliability the rangers three engines are very reliable. the 3.0 is considered a roach. cant kill em. (after 95s better change cam syncro every 70,000 tho)
