So I'm building a F22, and when I've built F23 engines in the past I usually use the K20 pistons, but the F22 doesn't have the same wrist pin diameter stock. One option I was considering was getting forged F22 rods with floating wrist pins, where the pin bore diameter is 0.866."

When I try to look up the K20 wrist pin diameter all I can find is the aftermarket piston wrist pin diameter which is 0.866." What is an OEM K20 wrist pin diameter? Also what is a normal pin-bore clearance for floating piston pins (since if stock is 0.866" then that leaves 0 clearance)?

I would like to just use OEM K20 pistons since they are more than adequate for my goals. I figured I would just ask here since it's more of a K-series related question. Any help is appreciated.

I read in an RSX FSM the piston (wrist) pin has a diameter (new) of: 0.8646-0.8648. I don't know if this was for the A3 or A2, or are they both the same?
