91 octane
New answer:
I don't know about the newer ones, but 88-91 prelude 2.0SI's only need 87 octane, as per manufacturer specification. The compression ratio is 9:1, so 87 is fine. The only reason you would want to use a higher octane than specified is if you have altered the engine in a way that causes higher combustion temperature, i.e raised compression.

What is high octane fuel?
Regular unleaded fuel is 87 octane. High octane fuel is any fuel higher than regular. 89 and 91 octane being the most common the consumer can buy. High octane fuel is not needed in most cars and is a waste of money if your car does not need it. It provides no benefit whatsoever in a vehicle designed to run on Regular. Octane is only a measure of how well the fuel prevents pre-detonation in a high compression engine.

because the high octane fuel prevents the igniting of fuel before the starting of engine
Can you run high octaine fuel?
It depends on the type of engine and how high of octane you are running. Octane slows the burning of fuel, so if it is too high of octane for the engine, you will end up burning out your exhaust valves because burning fuel is being pushed out of them. 92 or 93 octane that is available at fuel pumps as "premium" fuel is ok for most engines. I wouldn't run anything over about 100 octane.

It runs. High octane is what is required by high compression engines in order to prevent pinging. Unless you put the hi octane fuel in the oil filler. Then it will only briefly run before it explodes.
