10:1 compression is standard Honda compression..there are a few engines that are 9.5:1 and a few that are 10.5:1 but its pretty standard compression and the H and F series (except S2k) are all 10:1 
that is not true
F23A1 or 4 - 9.3:1
F23A5 - 8.8:1
H23 - 9.8:1
JDM H22 - 10.6:1
USDM H22 - 10:1
JDM H22 Type-S - 11:1
F22 - 8.8:1
while the B18C5 (Integra Type-R) motor has 10.2:1 and the JDM Type-R motor has 10.6:1. just giving them for comparison. please dont ask about putting them in an Accord. its stupid
