I am posting this for a friend. He has a 93 eg hatch with a jdm h22 in it. He wants to have it rebuild and wanted to use type s pistons for it. He doesnt want to have it done if its going to make the compression to high for smog. If anyone knows what it would be on a untouched stock h22 he would like to know. Also if anyone knows what are all the things he needs to pass the Ca emissions and the refs visual. His appt. is on the 13th.
