I was just thinking how it would be funny on my dad's '97 Odyssey.
I don't think it's possible to throw an H22a in, there are no mount kits.
Would another F-series work? The F20B? It would need an automatic, there's no way to get a shifter in the car, that would be some crazy custom work and you'd probably rig up a Civic Si style thing.

This is all theoretical, the chance of it happening is slim to really none.
I'm just curious though.

h series head, on f series block

 

the old odyseey's are accords basically.. the h will slip right in i think, lol

 

you can just mate an h23 to the f22 tranny i think, it should be able to take 160 hp
