Don't look at peak numbers. It doesn't tell the whole story.

The B20A started out in 1988, in the 3rd Gen Prelude. Then with the release of the H-series motors, the B20 went into retirement.

In 97, when the CR-V came into being and Honda needed a relatively torquey 4-banger...the B20A came out of hiding, got a new set of squeaky clean cams engineered for healthier low-end torque and went back into service as the B20B.

Then in 1999, if memory serves, the compression ratio was raised significantly to create the B20Z,. Again their intent was to provide their mini-ute with a wide torque curve to get the damn thing off the line. h:
