I think I'd like to make an 87x92mm engine and go up a racing class. I have a set of 87mm (with 23mm pin) pistons, designed to suit a 158mm rod and 92mm crank. The pistons aren't rod centred and thus if I need to buy rods, I may as well make them crank centred. I've searched, but can't find any data on the XUD11 conrod width. A look on the ACL site suggests they take the same bearing as the XU10J4TE. I know that doesn't necessarily mean the big ends are the same width. Can anyone confirm the big end width of either the XU10J4TE and/or XUD11J4ATE conrods?
