I need to find a part # for what looks like a tooled steel chrome top ring for a 100mm piston.
I have found that 928-103-90622 (for 928)has been s/s to 944-103-90282(for 944/944s) these are cast rings and break under boost....ask me how I know
So I ordered a set of 951-103-90102 (for 951 turbo) they are better...have a chrome face but still look cast to me.

Can anybody help me find the rite part # for this complete chrome looking top ring so I don't have to go through this rebuild again.


Thanks Rob
