According to this post I got from another site they are. how much you want for one with shipping.
Well, since I started this a while back in another thread I figured it was about time to finish what I started and make a definitive answer thread for anyone looking for piston, rod, crank and block specs or compression ratios of various H, F or H/F combinations.
Anything anyone wants to add to this thread post up whatever info or specs you have and Ill add it to this original post. I am putting up only what i have personally measured and or quoted direct from the helms manual. I dont want this thread to get cluttered with he said she said specs so Im asking that we limit contributions to first hand spec acquisitions and or helms manual references only. Whatever I have missed or havent measured myself, please feel free to post and contribute. The items i have yet to measure or discover I will leave blank until myself or another member provides the information.
Im going to start by adding a few specs that I can think of off the top of my head now, I will return later tonight and add some more info which will include a few CR calculations.
If I leave something blank and you have the information/specs plase post it up and I will edit this post and ad the new additions to the thread.

I have 3 good ones from an H22A4. I don't know if they're the same, but if they are, I got you.
[/quote]
Are they from a h22a4 92-97and below if so there good.
As long as it from a 92-97 and below i'd would be willing to pay 30 bucks with shipping. considering http://www.rpmrons.com/Hondakits.html this web site sells it for 50 bucks with shipping but they are out of stock. I can paypal you the money and you can send it 2-3 Priority mail United States postal service
why a 92-97 rod? they are the same. i have spare pistons(h22 factory CR), and spare h23 rods. a full set of both.
Because a 98 and up prelude use a 55mm crank so the rods use slightly larger bearings a 97 and below has a 50mm crank so the rods need to match the right crank..
oooo, rod bearing width. my bad.
