V-Tech is a company that makes phones and electronic children's toys; Hondas have VTEC, get it right.

That being said, the easiest way to do it is to just use the ECU from a VTEC Accord, preferably an OBD1 ECU. That way, all you'll have to do is run some wires for VTEC and you'll be good to go.

I'm not sure if Accord ECUs can be chipped or not. I'm guessing probably not, since the Prelude one's can't. If it turns out that they can though, then that's another option, send your ECU out to be chipped for your new setup.

I guess you could also run a VTEC controller, although I'd prefer to just have an appropriate ECU to run everything.

allright now how do i go from obd0 to obd1 ??

BrutalB83 · 11-06-2007, 05:22 PM

Ah, your car is OBD0, I was thinking it's OBD1. I would contact Rywire. They make custom wiring harnesses for Honda engine swaps. I would explain to them what you're wanting to do, and see what they say is the best way to go about it. I'm not exactly sure what the best option is for you.

+P28 chipped to run VTEC F-series

compare schematics, cut/move wires as needed

if your asking questions like these then dont attempt this swap. You're risking screwing up your daily driver by doing a mod that your clearly not able to perform for a measly 10 max more hp. If anything you would try and run something pre 96 for the sake of being OBD1, hell h-series heads fit on F series blocks.

on that!

I've always honestly thought that swapping the single-cam VTEC Accord head isn't really worth it. Unless you're getting the head and ECU for dirt cheap then you might as well just swap an entire motor for your trouble.

norcalgsr · 11-07-2007, 12:18 AM

Definitely not worth it unless the parts are practically free like you said. You can drop an H22a in there for under $1400 that will make a ton more power than any kind of head swap you can think of.

Yes, but the H-Series and F-Series are related, you can interchange parts between the two. And just because one motor is dual cam and the other is single cam doesn't mean you can't swap heads between the two.

Honestly though, I'd rather swap a whole H22 than do the head swap onto an F22, just for reliability's sake.

need2bfaster · 11-07-2007, 11:08 AM

agreed on the swap but right nowi dont have the funds to do so so im trying to do what will improve it little by little

save your money and little by little you will have enough for a swap

Prophit132 · 11-07-2007, 11:34 AM

Lots of h22's are available online even cheap ass ones on e bay if your on a tight budget. personally I would rather have a fresh 30 to 45 k JDM. But your ride your decision.

That doesn't really make sense. Why spend any of your money to do something that isn't really what you want? Just save it towards an H22 swap.

need2bfaster · 11-07-2007, 03:58 PM

ok every one well thanx and as for the ebay h22 id much rather go with the jdm 30 45 k are the b16 worth looking into or go right to h22

no b16, you definitely want the h22 for your accord

91_civic_si · 11-07-2007, 04:28 PM

Is the H22A swap worth it in an Accord? I say yes

The H22 and the F22 are related, so an H22 is a much easier swap. You can drop it right in, wire up VTEC, and you're good to go. You can even re-use your Accord's transmission, although the gear ratios suck compared to the H22 tranny.

A B16 in an Accord is not worth the trouble. You'd have to fab up custom mounts, and you'd have to for sure use a B-Series transmission. You can't bolt it up to your Accord tranny like you can with the H22.

Also, look at the numbers the B16 puts down. Yes, it makes 160 horse, which is more than your F22, but it also makes significantly LESS torque than your F22. The Accord is heavier than a Civic. It needs that extra torque to get it moving.

The H22 is the obvious choice here.

need2bfaster · 11-07-2007, 04:54 PM

thanks i didnt knonw that the h22 and f22 mounts were the same that helps out alot would i be able to use a tranny from an early mode prelude like early 90 or late 80s

need2bfaster · 11-07-2007, 05:31 PM

or what do u think about a turbo i have stock pistons though

BrutalB83 · 11-07-2007, 07:45 PM

Any Prelude transmission older than 92 won't work. Those older Preludes used a wierd version of the B20 that isn't compatable with much of anything. Any F22 or H22/H23 transmission would work, although I'd recommend using the tranny that goes with whatever motor you end up using as it will make the most of the engine's powerband.

As far as turbo goes, you can turbo on a stock H22, but I'd advise you to keep the boost low and make sure it's tuned really well. If you want to run a lot of boost you should probably sleave the block and invest in some aftermarket internals.

Actually, the F22 has a closed deck and iron sleeves from the factory, so it's not a bad candidate for boost in stock form if that's the route you're wanting to go.

need2bfaster · 11-07-2007, 08:40 PM

i think the turbo route would be fun for now i got a spare f22a1 i can turbo over winter and see how it goes

BrutalB83 · 11-08-2007, 12:54 AM

I think that would be a great idea, especially if you already have an extra F22 to play around with. That way you can see what boost is all about and decide if that's definitely the way you want to go or not.

need2bfaster · 11-08-2007, 05:45 AM

it has no pistons in it now but what pistons and turbo would u recomend or just buy a junk ebay turbo to mess around with for now
