H23 head on H22 bottom

[Trini Honda]

Has anyone done this? Is this something that can work?

Is it a good idea?

[blazedealh91]

yes can be done
but why? is it a v-tec h23 head ?
i think u have to plug one holes on the block that was for v-tec

[deevergote]

Can it work? Yes. With some modification.

Is it a good idea? Not really. There's really no good reason to do such a swap. It's kinda like having your dick shortened. Sure, it can be done (in theory), and it will still work... but why?

I think ive read somewhere that doing this swap with the non-vtec h23 head and h22 block comes out giving you more tq than just the stock h22 but i could be wrong. Im actually thinking of doing this also.

Get an F22B twin-cam. The H22's power is in its head, hence why the larger H23 isn't already more powerful. For more torque, I think you're getting the equation backwards and read about the 23 with the VTEC head. Geez, I had to completely revise my response twice while getting my head around such an absurd hybrid.

Again, "in theory"... half an erection, weak sauce.

You "read somewhere", and you're thinking of doing it? How about learning exactly what you're talking about before tearing into your engine. Slapping a head with less flow capability onto a block with smaller displacement isn't going to do anything good... where do you see an increase in torque?
People put the H22 head on the H23 block... more displacement = more torque (of course, that's not a great idea either, because the compression ratio and redline both drop... and you don't want either to happen with the h22 head.)

It'd still be full... just smaller.

But you're right with everything else. The H22 is made to rev, and have a large powerband due to VTEC. The H23 has no VTEC, but has more displacement.
The H22 block will offer higher compression, but less displacement. Most likely, you'll get a block that will rev higher, create power slightly later, and not be matched to the head's flow.

Then that's when i get a F20B lol

Is this true???....

[deevergote]

Is what true? You dug up a nearly 2 year old thread... please specify what it is you want to know.

Sorry I was just reading on some stuff here.. didn't realize how old it was..... But I was just wondering is this a bad idea too do ?

Why dont you read what deev commented and the other guys and ask your self if its a bad idea to do it...

Done.

[jdmboi type s]

done ... old picture but been running great for 4 years already

[deevergote]

good for you.

[CyborgGT]

jdmboi, what am I looking at there? Is that the head swap this thread is about, or just one of the stock DOHC non-VTEC H/F engines?
