Been doing some digging and looks like some years ago, people were entertaining the idea of using Integra LS connecting rods in the a20.
From what I've found, a20 rods are 137mm in length.
Those are 137mm in length.
Now I know the wristpin is a different size, a20 being 19mm if I remember correctly, but you could easily have a machine shop bore the pistons out to 21mm and even then get upgraded pins which is win win. Or have pistons made with that spec.
Thoughts? Cause that's not a bad price for forged H-beam rods if they could work.
