IT WOULDNT LET ME POST THIS IN THE FAQS AND HOW TO SECTION SO IM POSTING HERE LOOKING FOR HELP I have some 92mm je forged pistons i am trying to sell and have a potential buyer set up... they buyer wants to know specs on compression ratio, but i know nothing about them other than brand and bore size( got them with a parts car and dont have nothing to use them in), only two markings on them are 92m and je, is there any way to determine the compression ratio on them without having them installed in a engine? they potential buyer says je charges 75 dollars to identify pistons and i am hoping to get them figured out to make this sell, any help is greatly appreciated!!!!
