Has anyone heard of this being done. A shop by my house says that they have done a number of these. I didn't think it was possible.

Would their be a big diffrence between a H22/F22 hybrid and just a H22?

 

i looked in to it a while ago and decided it wasn't feasable.

 

well whats the reason for using the f22 bottom end, because you already have one or what? cause the JDM h22's are closed deck unlike the later model USDM h22a4's, so if you were going turbo then a jdm h22 bottom end should be sufficient... but for the labor it will cost you, and parts (if you dont have the f22 bottom end) then it might be worth it to go with just a complete h22 swap....

 

Yeah i have a F22B Vtec.

 

so, blue fang, you're saying I could've done it?

 

"We have also been successful transplanting Prelude DOHC heads onto the F22 (primarily from the Accord) block." PFISpeed.com

 

you can do it, but the F22 has an 85mm bore. the H series motors have an 87mm bore.

this means welding up and recutting the combustion chamber roofs in the H22 head.

yes, it can be done. but the $2000 required in head modifications can be better spent somewhere else.

 

Here, instead of modifying the head, just get H22 pistons and bore the F22 block to match. Don't forget the sleeves...

 

Or use an f23 block. The bores match up alot closer, plus you get a .3L of increased displacement.

 

Damn that's crzy , i never heard of that b4 . sumthing new .I heard about the f tranny on an h series motor for tha ppl who ca't afford tha whole thang...
