F20a to F22b swap?

Post by **clarelude23** » Thu Mar 31, 2016 5:43 pm

Hi all. I'm just checking if anyone has some experience with this swap. I had a quick look and couldn't see much.
What I'm looking to do is swap in an F22b(dohc non vtec) into my bb9 which has the f20a.
Reason being is that I have the f22 just lying there and I wouldn't mind another small project.
Would there be any compatibility issues? I know most of the components are common. Anything I'm missing?

I'd presume you will need to swap the ecu as well? And on a 5g the ecu is coded to the key??? (Immobiliser)
Would expect the exhaust header to be different too, but just guessing there really.

afaik the F20 F22 H23 manifolds are all interchangeable at least the 4g ones are

Intake manifolds, yes.

Header also fits with no modification, but downpipe from h23 needs to be cut shorter in order to fit on the rest of the exhaust.
