i just got done doing a compression test on my K20A2 motor...it ranged anywhere from 177 psi's to 189 psi's at WOT...cylinder one had 185 psi's...cylinder two had 181 psi's...cylinder three had 177 psi's...cylinder four had 189 psi's...

i've read before that good compression for this motor is at about 206 psi's (not sure if it was fact or someone heard it from someone else)...the problem with this, i have also read about someone taking their car into acura for a compression test and they got 185 psi's across all four cylinders and acura told them they had "good compression"...

So my question to you guys: What's good/average compression on the K20A2 motor? (if it matters...the motor has 5,600 miles on it...not sure if the rings have fully seated yet...maybe that's why number 3 is a little lower then the rest)...thanks

Edit: The Helm's manual doesn't say what good compression is...it just says it shouldn't be bellow 135 psi's and the maximum variance between all cylinders should not exceed 28 psi's...
