the rod length has no effect on displacement... thats stroke you're thinking of. Say you have a motor w/ 89mm stroke (like the LS) if you put 90mm rods, or 120mm rods, the displacement would still be the same, the piston would just be moving 30mm higher up
I personally have no idea what the gs-r/ls rod lenghts are though. :thinking:
