Cool. The F22B isn't rare, but hardly anyone talks about it on here.
It's like an H23, but it has no knock sensor (pretty sure). The F22A6 ECU should work, but I don't think it's optimal, especially if you switch cams.
You can swap the guts out of your dizzy to the new housing if you have to. I doubt if it's the same housing, and I have no idea what manifolds it uses.
You'd probably still want the DOHC Prelude PS hose, like a H22 swap, but again, I'm guessing. It should be a simple swap, but sometimes simple things take a while to sort out.
