Hi i got my b20b from noyanusa.com for 950 after reading all these post on here im wondering what compression motor i have, heres my list
96 b20b
head-p75-8
block stamped-p3f
75 cams
pr3 cam gears
no knock sensor
has a 2 layer head gasket
and the tall manifold

what do u guys think could it b the 9.2 cr one? or a 8.8?

 

Take the head off and see if it has PHK pistions.

No knock sensor = low compression, I think.

 

in all likely hood if you have a 2 layer you have 9.2 cr. my old b20 had a 3 layer and was 8.8.

a good way to tell is to dyno it
