thanks and it looks like i found my block ... i am planning on building it up and tearing it down 2 or 3 times to upgrade it ($$ issues) this time i wanted to focus on the ka probs like the shitty rods that broke out in the first place and new pistons aswell i know i wana bore the holes out and get bigger ones to (i dont plan on cheaping out eaitherfor two reasons)i was looking at the bc sires forged steal pistons that look all cool and shiney witch is all good and well but honestly

i dont know that much about motors any info on the main parts what they do and how they effect the over all power of the motor would be great..
i know theres the cams pistons rods crank timing chain valve springs tentioners and pullies that could all be potentialy be upgraded(based on after market parts sites)

on my block i read that i could also improve on the ka's exaust ports ... something about there angle ide like to improve this but i dont know what they are refering to or how to modify correctly

as always help is appreciated
