legally it is not possible. first of all honda ditched the h23 in 1996 and for your car to be legal it has to has a engine the same year with the car or newer. also if you decide to put it in you will need to adapt it from odb1 emissions to odb2, and no h23's were made odb2.
The tranny for the accord and the prelude have the same housing, and if u need to put a manual one, you might have to relocate the tranny mount on the right, next to the battery. Like blown teggy said you need axles for a manual tranny. the left one in an auto accord is 10cm longer than the manual accord. i do not know about the right one thou. the manual should be longer.
and i think that the reason he decided on the h23 is because h23 is not vtec and can properly run on an accord ecu. any complete h22 swap should come with complete engine and intake, manual tranny, original axles, a pair of extra axles, ecu and wireing harness.
