Compression Ratio of 1995 EX D16 vtec
9.2:1
Good for boost, leaves much to desire for all-motor duty.
Add some 1988-1989 Integra P29 pistons and have high CR for some serious all-motor power:

Your stock pistons have a dome of -10.1cc which means it has a dish rather than a real dome.
The piston pictured has a dome of +7.2cc which bumps CR way up and that means more whp and torque, but you'll need higher octane gas of course.
Play with these two sites for some neato results in CR for the SOHC:
