Is the processor on the piggyback board socketed or not? If it is I w you could replace it with......

Yes, the CPU is socketed. I don't think there is much more performance to get, regardless of the CPU - this is because of the 8 bit bus on the IBM motherboard.

I largely agree, though if you could use something with more internal cache that whatever the current CPU has, it could make up for the bus at least a little....... if it works with that board.... and the board supports whatever voltage it needs.... I doubt that this will make much difference though.

Looks like you already understand the above issue. If I changed the DMA controller and other support chips on the IBM 5160 mainboard, I could likely get the ISA bust to at least 8MHz. I did so on my

Oh seems your last sentence was cut off :(

Upgrading all the chips on your 5160 sounds like quite the commitment! Are they mostly socketed or are we talking desoldering with a re-work soldering station here.
