None of the forged pistons I've found run a wrist pin offset. K20 pistons are the same 30mm comp height, and same wrist pin as F23's. Even the rods have nearly identical specs, except they're 2mm shorter. I was certain F23's use floating 22mm wrist pins just like the K20, am I incorrect??
Well, I have a box of stock pistons and rods that I just pulled out in the garage, and I should have a set of stock K20 pistons and rods somewhere around here too. Shouldn't they both come out just by heating the piston in hot water and slipping the pin out? I guess that'll be my little experiment this afternoon.
