Hi guys, so my F20c had dropped a valve and looked like ISIS went there and had a party...
So i bought a second hand f20c from a member of the s2000 community in New Zealand (we don't have an easy access to any parts here).

It had a rebuild with resleeving, honing new top end blah blah. But it has rod knock.

I took it into a reconditioner and they showed me that the knocking was from the pistons rubbing against the walls... so they said I would need oversized pistons (something about +20?)

Would aftermarket be good or does Honda have a size that fits this?


Thanks!
