Did you do the test hot or cold? and did you hold the pedal to the floor?

How old is the motor, and have you beat the crap out of it?

That number is not too far off from the rest, but 150 is kinda low for a b16. Consistency is key, numbers don't matter too much as long as they are around the same.

Always use the same number of cranks for all cylinders. (I use 5.)
Always hold the throttle wide open.
Disable the fuel and ignition.
If you get a low number, put a teaspoon of oil in the cylinder and do it again. If it goes up significantly, it's the rings.
