Turbo? if so, how much boost?

Non turbo? why would you use 110 octane?

Well, as far as advancing your timing goes on an N/A motor, I would assume that you would want to at least upgrade the coils and plug wires before you run an octane rating that high. I've ran 100 in mine when my plug wires were stock, but it did fine. I'm not sure on the 110, so don't take my word for it.

Running anything over 87 Octane in an NA is detrimental to performance. 87 Octane is the optimal fuel for an NA engine.
