h23 crank in h22 - Honda Prelude Forum

jsmooney · 03-26-2009, 09:37 AM

I am posting like a **** here....

if I put the h23a crank in my h22, how much hp/tq would it add?

or, would it even be worth it?

You're just going to slap it in there?? Nothing else?

I've never seen someone just do that and dyno for numbers..
So I doubt anyone will know what it would give you..

You'll increase your stroke, but wouldn't be able to rev as high.. ((If it's all stock...))

i know there's more to it, it would have to be polished and balanced to handle the high rpms safely

i sent a question to honda tuning about the h23 crank into a h22 they said that its the same. the only thing thats different is the piston and vtec head
so i wouldnt think it would make a big difference

Said what is the same??

That the H23 Crank and H22 Crank are the same?

I think the rods (i'm pretty sure) are a bit longer and the crank has a slightly longer stroke

cranks are different, rods are different.

Honestly I'd just stay with the H22. You'll see a little bit of HP gain, but you'll also see an earlier powerband because of the added displacement.

but....more torque! I know some people have swapped cranks on here....

If someone just swapped a crank I'd slap them..
That's one of the stupidest things I've heard of. Unless there was valid justification for it..

How much more torque do you think you'll get from a "simple" Crank Swap?
Might as well just put the H22 VTEC Cylinder Head on the H23A1 block..
Specially depending on what block you're doing this in..
