You will need a lot of work on your car if your planning on running E85.
Ethanol biased fuels contain much more oxygen than petrol and burn "cleaner" emitting less CO2. But Ethanol is much less volatile than petrol and harder to ignite so your timing will need to be advanced by a considerable amount.
The injector's will need to be increased by a certain amount to add more fuel into the combustion chamber.
The reason Ethanol fuelled cars make more power is also due to the fact that ethanol contains more oxygen than petrol this means that you can cram more fuel in and thus make up for the reduced amount of energy per unit compared to petrol.
Other things to consider:
Ethanol is a very good cleanser and will wash all the carbon build up since you have been running petrol into your engine.
Ethanol can perish rubber and plastic parts such as certain lines in your engine.
Ethanol LOVES water it is impossible to separate all the water from ethanol fuels so a little will still remain in pump fuels. If you leave your car parked for a while there is a good chance you will get a layer of water in your fuel.
E85 cars do not like cold starts because ethanol will not vaporise easily.
Do some research on the internet and find out what others have had to do to run ethanol.
Im my opinion the B16B is a highly tuned engine Honda put a lot of development in designing an engine with maximum performance to be run on quality fuels you could find yourself in a world of pain if you start messing with alternative fuels.
Note: I am currently writing an essay for my uni course in chemistry on the use of ethanol as an alternative fuel so I have done a reasonable amount of research.

hey man thanks for the info...ill some more research...good luck in your essay

Cheers guys glad it helped wasn't the best write up ever but might aswell make some use of what i've lernt 
As Edu.T says Brazil is a big fan of ethanol and alot of cars sold there now are specifically designed to run on ethanol and petrol but converting a car can be tricky.

our H2 Honda Challenge car runs E85 and we had to up the injector size IIRC to 440cc.
It's been reliable and despite the caustic nature of the fuel, the fuel lines remain in good condition. One aspect we've seen fail stateside is when aftermarket fuel rails are used. It may be because the aluminum is not as high quality as OEM.
Our sponsored driver as also done a lot of research on this and another byproduct of using E85 is the lowered intake temps. It will run cooler and even in the blazing summer heat of Los Angeles, the car sometimes had problems engaging VTEC.
We later had to bypass this by having the Hondata ignore the IACV and other sensors - which caused another undesirable trait of an unstable idle.
