H22a head onto F22a1 Block

[Jtschupp04]

Can you put a H22a head on a f22a1 block? using the h22 timing belt will it drive the oil pump and water pump correctly? using the p13 prelude ecu will the prelude injectors run to rich for the low compression f22 or will computer compensate with long term fuel trim or should the f22 injectors be used.

i ve been told too many different things by friend that it can be done and that it can't im just confused share your insight and wisdom please. THANKS A BUNCH!

Ive never seen that done so i have no idea, it would be an interesting hybrid. I know the h23 head can be bolted up with just a few things done to it.

[Jtschupp04]

yeah ive heard of that too do you know what mods you have to do to make it work?

Yea blockwork...its pointless to put an efficient head on a block if you cant use it to its max potential. Your better of using an h23/DOHC f22b head like everyone else since its within powerband.

f22 block is very similar to the h22 block. The f22 can handle the head fine. The reason headswaps don't work out well is because people don't know how to maintain them.

h22/f22 has been done. http://www.honda-tech.com/zerothread?id=776837

Why not just go with the full h22 swap? Are you planning on boosting? Because I think that would be the main reason to keep the f22 block, other than that it seems kind of pointless

Not if you're hurting for money, it's not pointless.

It can cost less than $500 and has the potential to be better than a stock h22, with a stock frank(if that makes sense).

To take advantage of swapping over that head you will need to do some internal work to the block to get it to work such as swapping over cranks and shit. Doubt the F22A crank can handle constant beatings up there without some work but then I could be wrong. I forgot what Hondafan81 used for a crank might have been stock I dont remember. Then you get to have fun locking the pins in.

True enough, but if you dont DIY how much labour is involved with something like that? Plus the internal work? I dont know it might end up costing a little less, but a lot less? IDK

There is NO internal work needed.

It can handle the revs. Maintaining the engine is key.

f22b head on a f22a1 block

[d112crzy]

Uhh...that's the f22b1 head on an f22a block, basically a weak ass f22b1.

The most retarded head swap, ever.

Nm then Ill roll my n00b cart back to my corner. Anyway franks usually die because of low oil pressure as I recall resulting in spun bearings and crap. Thast if it is not taken care of.

yes the head can be swap and it can run just fine just watch your compression on the motor i used the the sohc vtec f22b1 block and used a h23 head and a f23 block with a h22 head. On the f22b's the comp is 8:8:1 by puting on the h23 head it droped lower to 8:3:1 and i am runing 18psi on a stock block it is reliable "But" you got to have someone who can tune good. When i put the h22 head on the f23 it raised the comp to 10:5:1 some where in the area it was puting out 225hp 178tq. So yeah to your answer it can be done.


To do it right is is what you need to do change the crank spoket to any of the h series change the water pump to any of the h series and change the water pump tube to a nonvetec sohc or a vtec sohc cause the one on the h series is too long for the f22 blocks oh i almost forgot you got to use a h series head gasket.

yeah i am planning on turbo im just researching because of my limited knowledge and experience. i wanted to do a full h22 swap but its just not practical right now. funds are limited as most know how it goes. thanks for all the input and thoughts.
