My car is a 96 LS Sedan Automatic, the motor in it now is Bottom half 99, top half I think 94(it has a 93 stamp on it, so I figured it was made in 93, but its from a 94 integra, the guy at the junk yard told me it would work fine with the bottom as I bought the whole 99 engine from him). . . Long story, but the 99 head was sent out for work and never came back, so got the 94/93 to get the car running again. . . you think this would cause a problem? ? ?
