ok im pretty sure i do have the obd1 vtec zc in my 91 si hatch....

and i just bought some Y.C.P high comp pistons. which are suppose to be the same as the pistons that came in the old d16a1's.

im just wondering what my comp. ratio would be.

thanks for all the help before hand:goodjob:

depends on head and head work done , but you can look up that part number you bought and it will give you more in details of your compression
