is the integra a d-series engine? hydro? if so, then i would think so.... i put one from a 00 EX into a 95 Si, but then again they're pretty much identical (drivetrain-wise). There won't be much performance gain, but it does feel much better in my opinion. i wouldn't buy a $20 one off ebay, as most ppl would agree; you never get more than you pay for.
