It seems there are different opinions regarding the possibility of boring the THS rod small end from 22mm to 23mm:

- Jim K. has told me that it could be honed, and as result the bronze thickness will be a layer of 0.5mm.

- THS people in UK said that to have a larger pin would require a new rod design to be made. they pointed that the minimum quantity for a new design is 5 sets.

I'm not so confident with a 0.5mm bronze layer on the rod small end, IMO is better to increase the rod housing for the bronze from 24mm to 25mm, this way the bronze thickness will continue being 1mm. Can somebody send me or post a sketch of one THS rod? I can model it and make a simulation of before-after modification of the pin diameter.

New rod design can be a good idea if more Alfa enthusiasts (at least 4 more) want to make this same engine modification, and this can be an oportunity to design the rod with all the features to match the selected piston.
