ok i have read that the 4age head gasket fits a 7afe so i would like to know if i use a set of 4agze pistons with a 2mm head gasket will i be ok for 10-12psi of boost or will the gze pistons raise the compression to much even with the 2mm steel gasket just need some input befor i buy parts i dont need thanks guys

lagos you do realize stock compression is like 9.5 on a 7afe i think
or its in the 9s...all that is required stock is 83 octane...
an Emanage with 94 octane @ a 10:1 CR should be obtainable with minor implications.
and actually those hondaz are on pump gas
**** add some H2o injection for knock control

@ .9bar doggy was making 206whp on an unopened motor
increasing the CR and tuned @ the same .9 bar it could probably see in the 220s
and some water injection maybe 230s

do we really know? no
is a higher then stock compression build possible? yes
will it take research and some trial & error? yes
does this mean we shouldn't try? no

I'll even donate the motor for 40$ to do it with

doggy DID NOT make 206whp
206HP.
10:1 compression ratio in a 7a, without a standalone, = boom.
