I have an f22 b2 and cant find affordable forged pistons, i was wondering if anybody knew whether the h22 pistons would fit, they are cheap for forged. Or where i could find the info. Thanks

I installed a H23A rotating assembly into my my friends Accord F22, and it worked, just need to make sure the main journals are the same diameter cause they had two different sizes of main journals. I think the H23A is a 50mm and the H23A1 and H22A4 are the better 55mm, except the 1997 H22A4 it had the 50mm mains or vise versa. Best to take 2000 grit paper with WD40 and spray the block clean on the inside and outside and LIGHTLY SCUFF the cylinder walls cause they are FRM sleeves "VERY SENSITIVE" and you will want to install new rings in the Slugs to help them seat. They are 87mm pistons right? If so you should beable to install the Nippon 10.6:1 pistons and with your head cc being larger than the H22/H23 your compression will still be boost worthy, I think around 9.8:1-10.2:1 depending on if the head of the block has been milled and what size headgasket thickness you use. I may be wrong a bit anyone else know the exact compression of this swap.

I know the stock comp ratio is 8.5:1 i am looking at forged pistons that are low comp for h22, are you saying that is it possible that it will be lower in the f22 vtec? I am aiming for big numbers here 450-500 whp. Wanting high boost and low compression here. Thanks

It really depends on what rods and what the cc volume s in the head. Like if you use the F22 crank and put the H23 rods on it you will lower the compression more. Now if you have the H23A crank in and use the H22 rods, you will be above the deck height so you will have to raise the wrist pin on a CUSTOM MADE piston. Thats what I'm going through now with my H23A crank,H22A rods, Weisco Piston, back up set up, Long stroke, LOOOOONG ROD, 90mm bore, Benson sleeves. I'm not that fam. with the F series, but I know the H's and the F's share alot of the internal designs. Just search for H22A build specs and also search the F22A build specs. Or contact this guy he helped me get the specs on how much I needed to raise the wrist pin on the skirt. http://stores.ebay.com/F22-Parts. YEAH YEAH YEAH EGAY I know but he deals alot with the H's and F's.

Dude, quit spoutin off random info that's wrong.

OP: h22 and h23 have 87mm bore, f22 only has 85. seems like a helluva overbore to me.

THIS JUST IN!!! H SERIES PISTONS HATE DETONATION!!!!

All pistons "hate" detonation. :1

OK ---- head, I was talking about the RODS and CRANK I never said anything about the PISTONS hense I said to talk to the F22Aparts guy. And when I did the swap in my friends car we used CUSTOM PISTONS, with the H23a crank and H22 RODS on a 50mm main. BLOW me for assuming that I was talking about the pistons. And a 2mm overbore isnt that bad on a sleeved 2.2 I went 3mm my my back up block. It's not a small 1.6 sohc

I didn't assume anything. I just pointed out the uselessness of your jibberish post.

The guy asked if H22 pistons would fit in an f22 block, he didn't ask for some incoherent rambling about swapping an H23 crank in there (no need, his f22 already has a 95mm stroke) nor did he request your advice to scuff the frm sleeves with sandpaper and wd-40 (the f22 has cast iron sleeves)

Your brilliance has us in awe, please share some more of your ignorance knowledge
