    What kind of compression ratio will my car have with this setup? It is a 1994 usdm b16a3 with spoon head gasket and ctr pistons. Thanks Jeremy

    you must have used the cspeed comp calc which is wrong for that setup. they list the b16a/b blocks being the same, which they are not. i think he would be more around 11.7:1

    I talked to a shop today and they said that, "Your motor shoould have about 12.3 to 1 cr when it is done." I am really not sure he said something about my head about the valve chamber design I am not sure. Thanks Jeremy
