like the title says does anybody know the compression ratio of a sohc zc (the engine was made in 1991 if that matters) because i have seen 9.1:1 and 9.6:1 but am unsure of what it really is. By the way i checked the compression and it was at 180psi in all cylinders does anybody know what that equates out to?

 

there has to be somebody that knows this.

 

9.1


9.6 is for the dohc zc
