thanks jersey
I was hoping to get a definitive answer & not pull apart my R8 & k3 to check if the rods are interchangeable.
I remember vaguely reading that all Argus 21 engine connecting rods are interchangeable but not sure if that’s accurate.
I’m aware of the K3 being somewhat identical with the D3 but not sure if the D3 rod alone can be replaced and still keep the k3 P/S.
I’ll do some more searching and send Lutz a msg for some guidance.
your help is much appreciated, thank you
