Compression

What is the stock compression on an 89 Civic Hatch 1.5 D15b2?
I need to find out whats wrong with my motor!!!

idk the stock compression, but have you done a compression test?

you talkin compression ratio or like psi per cylinder. because for a d series its about 9.2 to 1 as far as ratio and i woud lsay between 155 and 170 or somethign as far as psi. i msure im alittle off. but tis my best estimate for u.

my b16 runs 180 psi in each cylinder

Yea, they got it close. I don't know what the exact psi is, but 155 should be a minimum, its a sign its starting to need a rebuild but still running alright. If you end up with something around 100 or lower, you have bigger issues and at the point of needing a rebuild badly. If its like 25 or less, better check your valves because either 1> one is sticking on you, 2> one is bent, or what i ended up getting 3> broken valve which is usually a result in 0 compression.
