can a convert 1.6 N/A to Turbo?

Hi
Thanks for all the information. Without full knowledge of the three hole comment I think you are referring to the notches or holes that show how thick the head gasket, and you are recommending the thickest one to ensure the compression is lower.

Or are the three holes for something else that improved cooling or oil circulation between the head and block?
