can i put a h22 head on a f22 block?
That is turning a F22 into a H22....the blocks are the same, only diffrence is the head, so its a pretty simple swap. As for wiring, just read up on a H22 swap and your all set.

Not really... The crank, rods, pistons, and bore are all different.
dcskater6767,
There are links to the head swap in the swap section of the Accord FAQ.

if you're going to turbo you accord i would definately recomend putting the h22 head on, much easier to get quality mani's and the f22 block is much better that doing a straight swap if you plan on turboing

YUPP CAN BE DONE THERE ARE WRITE UPS AS SAID BEFORE.
THERS SOME OUT THERE. HELL HEREIN THE FORUMS MAKING PRETTY GOOD NUMBERS IM THINKIN ABOUTIT

hope you have a large amount of funds. the blocks aren't exactly the same. but the time ,effort and money needed to make it be as reliable as a complete h22 might not be worth it. the h22/h23 is more common.
so flight50 ur saying that if i plan to do that its going to cost me alot? and the reason i was thinking about doing that is so i can up my horse power while i start to save up for the h22 or h23 block or maybe just go ahead and turbo the f22 block with the h22 head.
this setup is appealing to those that want to go turbo but don't want to worry about sleeving the block.
Read through the threads in the FAQ and ask those who have actually done it how hard it was, how much it cost and if it's worth it.

people like the F series block because of the iron sleeved blocks striaght from the factory. The H series blocks have a FRM (which I believe is Fibre Reinforced Material) sleeved block that isn't as boost friendly and doesn't accept forged pistons (though there is a company that claims to have a coating or something that allows forged pistons to work just fine with FRM). Or atleast this is my understanding of it.
Yes, the H22 and H23 blocks both have FRM sleeves. Mahle makes the "FRM compatible" forged pistons that TouringAccord mentioned, but as of right now they are getting mixed reviews by those on this site that have used them. The FRM sleeves are actually quite strong, but become the problem when you try to run forged pistons.
An F22 block with an H22 head has a compression ratio of about 8.8:1 if I remember right, or at least somewhere around there. An H23 block with H22 head has a compression ratio of about 9.3:1. Both ratios are boost friendly, really. The H23 does have a larger bore, which matches the bore of the H22. The larger bore should produce slightly better torque numbers.

look in the prelude faqs...there are like 4 different write ups for this... I am working on doing mine right now. I boosted my f22a1 and had great results, but when I had a bearing start to go I parked it and started this project just for the fact that I will flow better up top...The f22 handles boost extremely well and it is in my opinion a better route to go than a h22 swap alone, but if you combine the two then you get the best of both worlds. It has sooooo soooo much torque, but anywho It can be done, it has been done...Just search man
P.S anyone want to donate a h22 head to a good cause, or sell one? It doesn't have to be in great shape just rebuildable

just my two cents. i'd boost a f22 before i spent money in a hybrid f22 bottom and h22 head. i'd prefer to spend the money and build the h22 block and boost that. after all your resleeving for insurance, higher boost numbers than the typical 6-7psi with stock h22 bottom, and you have a greater hp/tq output when built correctly in which no h23 or f22 can touch when the same upgrades are done equally.
The H22 longblock is more expensive than the F22; however since they share many characteristics, sleeving the F22 will allow you to achieve the bore diameter you want and the insurance of block strength. From there you only need to bluprint your rods and crank for the desired R/S ratio. This is an ovesimplified explaination but a brief overview of my actual plans. The bore size I chose is secret, but from there I'll build it, and boost it with the H23 head.
Torque for days!

And the point of keeping it secret? :rolls eyes:

well if your boring over 89mm i hope you have the money to run nothing but race gas. thats gonna require a perfect tune in order to keep her running. not saying it can't be done by any means though. is this a daily or a track car.

HAHA. Because you're a honda god and we would all copy you.
What a tool.
