you can't tell from the cylinder bore. from the outside they all look the same. from what i remember, if the head is black=corsa, if the head is silver=contessa.

Never buy a bore kit second hand, if you can't afford speed then stay away from it

polini kits are 47mm, whats this 48?

I have a scratched used polini bore (which I sneakingly think is a contessa) and was wondering if I could overbore (I'm not sure honing will take out the scratch) to 48mm. I wasn't able to find a 48mm piston so I kinda gave up on it.

I would think being from Hawaii, I'd say the probability is >95% that its for a DIO. We throw away AF05s.
