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 smile.gif just need some input befor i buy parts i dont need biggrin.gif thanks guys

Hum... I think you'll get too high CR with 4a piston and 7afe head to turbocharge it ...even with the 2 mm headgasket.

Claude

7afe head + 4agze pistons= 11.06cr
in NA form if you can get it to the low 10s should be fine
