if i increase the rod length to 159mm...what else would that affect? the reason i ask is b/c if you increase it to 159mm, you succesfully change the rod ratio to a very nice 1.75303 ratio. would there be a problem with the rods hitting the cylander walls, or the piston being moved too much?
also, would the stroke change?

With a rod that long, you're going to run the pistons right up through the head. The pistons already come up to the top of the deck of the block. There isn't much valve/piston clearance. You might be able to increase the length of the rod by about 1mm, but I think that the deck of the block won't be high enough.
You could try getting custom pistons made, and move the wrist pin up, but again, you would only be able to move the wrist pin up only 5mm or so. Then you would have to get custom rods made as well.
Changing rod length and piston configuration won't affect stroke.
