You can convert a f22ax motor to vtec but doing so requires swapping the cylinder head.
This particular swap is covered in our FAQ section.

There is no way to convert a f22ax cylinder head to be a "vtec" head though.
Vtec cylinder heads use special oil channels, lost motion devices, and rocker arm assemblies that are not compatible with any f22ax head.

In the case of the oil channels and lost motion assemblies, these are components that must be incorporated into the original design of the cylinder head as a casting.
It isn't the sort of thing you could "bolt-on" and convert.

Your best bet is to stay with the head you've got or switch to a f22a6 head, which has the most aggressive cam profile of the f22a motors.

If you really want vtec you could go with the B1 swap outlined in the previously mentioned FAQ but unless your installing head studs or have the head off for some other reason, it really isn't worth it.

I just swapped from an f22b2 to a f22b1 head on my car, as I was installing headstuds anyway and it has proven to be quite a hassle addressing the smaller issues with the swap.

Such as?

Only ones I have heard to have issues was from lil kids slapping a head onto the block, cheaping out as much as they can just so they can despretely get their vtec.

If you have realtively decent motor knowledge and you research before doing it, it will be problem free.

Just a suggestion, do with it what you wish.

IMO the hybrid F22 block or F23 blodk w/H22 head swaps are highly overrated. If you don't mill the head or put in larger compression pistons your stuck having to boost it. After doing the swap with no mods, the compression ratio is lower than the stock F22A & B engines.

If you want VTEC the best bang for your buck is to swap in a complete H22 engine. If you want to stick to SOHC VTEC. Then do an F23A1 swap with a larger cam in it. Both of these engines fit your car with little to know physical modifications. They bolt up to your current transmission as well.

I am really hoping to someday swap an H22 into my Accord. I am very pleased to learn that my transmission will bolt right up to it.
