Default What's considered good compression???????

I've looked on Google and can't find anything that directly answers the question. I have a 97 civic with a STOCK D16y8. I did a dry compression test on my car and all four where around 170psi.

Thanks in advance for you input and help!!!

You can't find anything that directly answers your question because it varies by elevation. As long as all 4 cyls are within 10% of each other, and above 150, you're fine.

Anything under 135 is poor. Some say 125psi.
