Re: f22a1 converted to h23 quetion

im running a f22a1 engine right now, but i bought this car as a project, it has a lot of problems with it, im changing out the heads, intake manifold, iacv, fitv, upper plenum, and throttle body with h23 parts i was wondering if it would be better to change out the heads and intake manifold with the vtec h23 parts and getting a vtec ecu or to just run non vtec

Re: f22a1 converted to h23 quetion

May wana save your self the trouble and just do a complete engine swap. But if you really want to swap out parts you should just stay with F parts. My .02 cent And in regaurds to "better" (very tossed around term here) what are you going to use the car for?

Re: f22a1 converted to h23 quetion

im not sure what im using the car for yet, i bought it as a project. and the parts i was getting from the h23 i was going to get them from a junk yard and clean them. i also heard that running a f block with h parts has good performance behind it. but i will take what you said into consideration.

Re: f22a1 converted to h23 quetion

''stronger'' sorta depends on the usage. If you figure out what you want to do with the car. Like Boost, N/A, gas sipper or what ever then the words stronger, better will come into play. I feel that before you go any further with your progect you should read up on head and block combinations because there are quite a few to choose from and figure out what direction you want the project to go in.... And btw before some on flames you.... unless you have one of those super rare v8 F22s you only have 1 head

Re: f22a1 converted to h23 quetion

Yeah. It would be SO much better to just swap a whole H23. The F block isnt much stronger, and everything doesnt exactly just bolt up. read a little on frankensein engines on here I'm sure there is a write up or two.

first off, you arent going to find an H23 VTEC head in ajunkyard here. It's a JDM motor.

So you have two options.
Easiest-H23 head
Performance-H22 vtec head

there is a lot more posted on the H22 head swap, its VERY common. That said, aside from some ports not quite lining up (don't quote me, I'm not positive) the H23 head swap would be a little easier I think due to not having to wire up vtec and all of that.

Bottom line though...

BEST and easiest...what I would do in this order
First make sure you know EXACTLY why the car is running like it is...don't just swap stuff out
Just swap the parts for new F22 parts...
if not then full H23 swap. Dont wanna do a whole swap?
H23 head, if not
H22 vtec.


oh also, if the head is fine you CAN get some decent gains just swapping out the intake manifold and upper plenum from the H23, and either wiring it up for the butterflies or hooking them up to vacuum to open arounf 4k rpms.

Re: f22a1 converted to h23 quetion

well what you should do before we begin telling him what is easiest we should deff find out how mechanicly incline he is... and we should deff tell him that if he swaps out a H head he will need to bore the block a bit. Thats why i suggest F parts like the F22b SOHC head or the F22b DOHC

Re: f22a1 converted to h23 quetion

True. I also think that there is an oil or coolant passage that doesn't match up on the h23...another reason I was recommending F parts first.

I probably shouldn't have assumed he would automatically be able to handle that just from him stating he was replacing those parts. But that's why I listed those things in that order lol. F parts first, swap...etc.

I personally think a swap is easier than having to port a block and do some machine work just to put a head on.

Re: f22a1 converted to h23 quetion

Im already aware of the boreing haha, and sorry i always accidentally say "heads" instead of head, and the problems im having are fluctuations caused by the iacv, and i have a bad throttle body. theres also an oil leak. if i end up going with an h23 swap do they match up with motor mounts and tansmison from the f22a1 or would that have to be replaced also? and most of my other problems are just wiring in the dash and such wich is easy ive already fixed most of it.

Re: f22a1 converted to h23 quetion

H23a1 swap would be very straight forward. Your tranny will bolt up and everything. Only difference is the h23 is external coil and the IM butterflies.

An h23 blue top you would have to convert that engine to obd1 and run a chipped p28. Not too bad.

I think though you might be good just swapping in the h23 plenum, throttle body, and intake manifold.
