i just did a compression check to see check out things and the results were

4 3 2 1
180 175 175 175


keep in mind this is a 9:1 block with a gsr head . which i believe would get me around a 9.3:1 total compression . not sure though

let me know what you think about the #'s

 

if its a jdm b20 then its 8:8:1 comp, the usa b20 is 9:2:1 and with a gsr head its the same, good numbers tho.

 

its a built block with j.e. 9:1 pistons

 

sounds about right........my 9:1 B20 pumps out about the same........

 

thanks guys
