Our market was a little different to overseas, for one we didn't get the 1.6lt versions, only 1.8lt and above. Our 316i badged e36's have a 1.8lt 8valve motor, early models ran the M40B18 with V belts and later models had the M43B18 with serpentine belts. The M40B18 was the last BMW motor to run a cam belt, they then changed to timing chains from then on.
Our early e36 318i ran the M42B18 with v belts and around 1994 changed to serpentine belts. Lastly our e36 318is ran the M44B19 with serpentine belts.
