Sorry guys I dont have anymore info on these pistons or whether you could use the same e15 rods. Its a shame I cant find a site to check these other dimensions to see if any e15 stuff can go into the a15.
Your right dd shorter rods would do the real trick but maybe theyll pop pistons out the bottom of the bores

If not it would be nice to lower the deck of the block about 2 cm!!! and make clearances for these shorter rods and pistons along with shorter pushrods and whatever else is needed. It would be nice to also adapt some kind of crank angle sensor get rid of the distributor, add electric fuel pump and then grind down the fuel pump, dizzy and power steering webbing safely to reduce a little engine weight without weakening it. The real thing Id love to see is a pic of 79mm bores to show how much meat is left in between the walls. Is it true the bores are offset to allow for this to be feasible after x-raying the block for clearances?? Feral any pics in your library of stuff?? has anyone ever contemplated or could it be possible to make a one piece sleeve kit grouping all four cylinders like that used on high hp alfa alloy motors instead of seperate sleeves to allow for an 82mm bore for the a15? or is it impossible? I think I better get off the turkish coffee and sweets and stop here too.
