Yep the d15b7 has 9.2:1 compression, but the d16 has 9.5:1 compression.

Within 10% of eachother. not sure what it would read on a compression test

yep that is what i was referring to in my original post, not the D16Y motor which i believe has 9.5:1 C/R. all the D16Z6 motors had 9.2:1 C/R just like the D15B7.

i don't do compression tests normally cause i don't have the gauge setup yet, but when people post up their cylinder psi readings they're normally in the 180-200 range. but of course some are higher/lower depending if they're stock or not, if the C/R was increased or decreased etc. some readings may be well above the 200 range, and some below 170-180 range too.
