Does anyone know what needs to be done for this swap? what sensors need to be relocated or what not. Trying to find a replacement motor for my h23a and they want way too much....so the F22b is looking pretty good for $750 less.

 

Just to be clear, you mean the JDM DOHC nonVTEC, yes? If so, very little needs to be done. If you plan to reuse your P14 ECU (the P39 ECU is damn hard to come by), you'll need to mount a knock sensor under the intake manifold on the F22B. Other then that, pretty much a straight replacement

 

doesn't sound like much fabricating at all, thanks man.....anyone else have anything else they can think of.

 

Some of the brackets (AC, PS, alternator) might be slightly different but you can always swap the H23's brackets over to the JDM F22B. It is virtually the same as the H23. If the F22B EX manifold is like the other F22 SOHC engine it will ahve the O2 sensor way up at the fron tof the car. If that is the case you can use your H23 EX manifold too. Mix and match and it will all bolt together. Good luck.

Last pictures I saw of a F22B, it came with the H23 style manifold (4-2-1), so he should be good there. If he feels like investing in a Megan header, now would be the easiest time to install it
