I have a d15b vtec that has 9.3:1 compression. What is the thinnest head gasket I can buy, and what would that raise my ratio to? I tried going here: http://www.knology.net/~jediklc/D.htm but I have no idea what some of the specs are or even where to find them.

 

bumP for me too...

 

OEM and remove the middle layer. or if u wanna go really extreme u could always try running 1 layer. but id stick with removing the middle layer

 

it'll bump it maybe .1-.3
