i think 210 is about right... and if its across all 4, that should be a good indication.

you might as well just hit some nos on it, my friend had the same kind of compression on his gsr, shitty, so we hit a 100 shot on it and ended its life. Hey K20 its me enrique, i heard you broke the 13's

It should be higher than that. My 99 B18b1 w/55k hit 205 on all 4 cylinders.

The Helms says that the nominal range for a B18C is 270. Considering the age and mileage of you motor, I would say you should be around 220 in all 4 if you took care of it. What year/mileage are we talking here?

how do you check the compression?

To check your compression remove all spark plugs, grab a rubber balloon and insert into the spark plug hole making sure air doesnt leak out the balloon, crank the car a couple of times over with your foot at WOT, the balloon will then fill with air, once the balloon stops getting larger tie a knot and measure the diameter of the balloon. Compression is calculated by the diameter of the baloon X number of cranks .

These Pics demostrate everything:
