I'm putting a turbo that can push up to 16psi in my 1991 323 1.6l 8 valve... I was wondering if putting 2 head gasket instead of 1 would be enough to lower the compression?? Any help would be good thanks

Later

 

I doubt that using 2 headgaskets would work for long. You'd probably be better off having the pistons machined slightly, or opening up the combustion chamber. Another option might be to get a thicker headgasket, if you can find one.

 

Thanks for the feedback man. I have a new question now...
Would anyone know how much it costs to get the pistons machined or opening up the combustion chamber?

 

Thats cool then, How much boost will I be able to put without blowing my engine?
