www.hmotorsonline.com is prolly your best bet

the engine bay for the prelude and accord gens for your car and the h22's years are nearly identical, so only minor mods are needed.

some say since the h22 weighs more the steering get a little messed with, but most ppl dont find it a problem. your accord will be jsut as fast as a prelude most likely but it's a definate step up from the f22 you have now.

think about things before you do them tho, the h22 has been called a clunker, and someimtes i wonder if the only reason it is popular is because the engine fits in so easily, i think we are all just envious that japan got accords with h22's from the get-go.

note: the increases are signifigant, but the prelude and accord are so much alike that it's not really a worthwhile transformation, it's like having a prelude that looks different, it still isnt meant to be a racecar, and you have to rev it so high to get it to the HP numbers that you'd see the increase in that it makes no sense (daily driven you'd rolly only rev past 5 or 6 once or wice every few weeks) and above 5k is where you'll notice it the most so it is your decision.
