Here are some numbers, can yo tell me if this thing is healthy? I'm a little worried about cylinder #2! Here are the #'s 240......221......235......236 They dont seem to bad to me but i just wanna run it by you guys just incase. Thnx

 

oh yea this is a gsr

 

stock GSR? if it is, nothing to worry about. My recent compression test looked like this:

210...210...206...150

yeah that is a bit on the high side, maybe carbon buildup? you should be ok though cuz they are within 20psi of each other.
my gsr came out 210 212 220 212

what are good compression numbers for a 96 ls...i'll be doing one this weekend....

 

Your cyl. reading 150psi should worry you (50+ psi diff. from rest.) But, neogenesis2004, your #s look fine.

B18B1's should produce roughly 200 psi of compression per cylinder. (Although yours is a 96, which may show slightly lower numbers.) Anything above 130 psi is fine, provided that the variation between cylinders is not excessive.

 

It does...I'm thinking bad exhaust seat or something because the car is not running horribly bad. At any rate, enginge gets rebuilt in April...

hah I beat you... 185, 180, 155, 160 something in my car is hosed heh also for a stock GSR (well, it has a CAI that's it)

 

can you do these tests yourself or do you have to take them to a shop?

 

You can do them yourself. Go to Kragen and pick up a compression test gauge for about $30.

EDIT: In fact, it's so easy that I tested 2 cars at our last Nothern California Integra Meet. Did it right in the parking lot. Probably took about 5 minutes per car.

is there a web page that shows how to do a compression test?
