70mpg is alot more then i ever got .
with a 1987 ford escort pony with a 2.3L 5 speed swap
I got 47mpg
and with a 1978 ford fiesta 1.6L I got 65mpg but this one of the smallest cars ford ever made .
now its a different story with the ford tempo its big and heavy but that 1.9L will be the best swap I could do to it I have a 2.3L/2.5L but that is modded to be in a race car not good for a eco modder. it has too much lift and duration and the cpmpresion is 240psi
so the 1.9L is the best . I keep you posted this is a on going project it will not be done in a week.
