    can anyone tell me the bore size of the BJX, i have melted mine in a conversion :/

    BJX out of the polo 9n. Need new pistons with 8.5:1 compression. may consider either boring it out to 82mm or bore and sleeve the 81.5mm. im just guessing the sizes though :/

    I think you will find that they are 81mm standard.
