my friend has a 96 accord 4dr with the F22A in it and i was wondering if there is a Vtec head that would match up to the block, what other parts would be needed and how much it would cost. Also how would the performance compare to doing an H22a swap. thanx guys

 

The VTEC head swap on an F22 is not economically feasible. The H22 swap would be cheaper and produce more power.

 

why not? It just bolts right up without any modifications and just needs the VTEC solenoid to be wired into the new ECU. I assume that the former response was talking about a h22a head on the f22a block - and in that case, he is correct, but if we're talking about the f22b1 then shoot, it's a cheap way to gain 5hp over the f22a6.

So with my factory f22a in my accord right now (90 accord lx coupe) I can put a vtec head from the later accord (94-97) on my engine and it bolts right up? I know I need an ecu and also a vtec solenoid and other things, but it cant bolt up?

 

It's not just the head you'd have to change. You'd have to change the manifold, add some wire for the O2 sensor, do some wiring for the VTEC, change the ECU, and a few other things I'm not sure about. I don't think the bang for the buck would be too good.

 

you could buy a f22b1 and swap it in cheaper than doing the head swap...

 

why throw 1000 bucks into a damn head and install for VTECH yo and 15 hp?

 

ok, its VTEC, why do so many poeple get this wrong...

 

he was just making fun of vtec. look at his SN...

 

"why throw 1000 bucks into a damn head and install for VTECH yo and 15 hp?"

bOo, Wat Ya tAlk'n about? V T E C H, Vtech like Honda TECH..
Vtech Yo

 

why would you waste money on somthing so stupid.

put the money towards a swap....or use it to pay someone to teach you some common sense.

 

Allot fail to realize that some people just have access to these parts at a really good price. And it's not a bad way to get some more power. So it's not really a waste of money to some. But maybe a waste of money to other because they have to pay to much for the parts and then pay someone else to put it in for them.

But if you wanted to do it for lets say a 1990 LX then you would need the head, P0A ECU (1994-1995 EX ECU), Intake manifold, exhaust manifold, and alittle cutom work on the exhaust because of the difference in headers. You won't need any extra O2 sensor wiring (You would if you where converting OBD-O to OBD-1 but the 1990 Accord is already OBD-1) and all you'll need to do is run in the two wires for the Vtec solonoid to the ECU.

So each to his own. You could do this conversion yourself for between $300-$500 depending on your source for parts.

It's not a bad idea considering all you gain (More power, tunable ECU, etc.). Now is that worth the money to you???

 

500 is 1/4 of an h22. nuff said.

 

What the hell does that mean??? So you're saying an H22 swap is 2k? So what does that have to do in comparison to a cheaper worth while mod?

I don't know where your mentallity but consider this. If you invest 2K on your F22B1 you'll blow the doors off any stock H22 swapped car. nuff said.

 

thats funny...you throw you 2k into a f22b1 let me know how much power you make out of it, sure throw it on the bottle and after you fry your piston rings then we will talk about the 2k you blew

 

you also have to drill some oil lines into the block to match up with the vtec head. then with crap like this you have to wonder how reliable it will be especially if your doing it to some old motor.

i was selling a full F22b1 swap with 100k on it for $450, that is your best bet.

 

if you can get the parts for cheap, why the hell not??? im sure you could get the head and manifolds off a junked ex for pretty damn cheap. if you cant afford the swap, why not do this in the meantime???

 

you've been watching too much F&F, a proper nitrous system wont fry anything but your competition

A head swap on a f22a is not a terrible idea if you want to do an all motor build, if it is preparation for FI then it is not really worth it

A head swap is not a great bang for the buck unless you have access for everything very cheap

consider the h22a long block on an f tranny, h22a long block = only $1200 for a gain of roughly 75-65hp, thats bang for the buck....

 

you guys were talking about a complete swap being cheaper here is one for REAL cheap but you will have to sell the auto tranny http://cgi.ebay.com/ebaymotors/ws/eB...category=33615

 

Busted, the reason I say he needs extra wiring for the O2, is because on 5th gens F22B2, the O2 sensor is on the manifold, since the manifold is a short 4-1, but the B1 has a 4-2-1 manifold with the O2 sensor just before the catalyst. It does require longer wiring, I do believe.

Nick M, are you buying the idea of an H22 swap with the original F-tranny? I am convinced that with proper tuning oriented towards torque, even without FI, it could be an excellent compromise between power and fuel economy. Of course, the 92 fuel...

 

yeah i have one

everyone with such strong opinions about it has never driven one, its not that bad, the lude tranny would give me alittle bit more acceleration, but in actuality its ok, my car traps at 93mph

before i decided on whether or not to keep my F tranny or just wait longer and get an H tranny i drove a 96 prelude vtec and a 99 base model vtec

with my Aasco flywheel, no AC or PS and a straight intake (see the wrapped intake thread), the throttle response and the quick revs sorta make up for the longer gears, when people ride in my car they dont even know its an accord tranny until I tell them

with that said, it does work fine, but an h22a tranny is ideal whether its for NA or FI, long gears and FI are just a myth

the extra 3mpg u get with the F tranny or whatever on the highway is a trade off for alittle acceleration i guess, but this isnt a site about fuel economy, i could care less about mine

the f22 gears seem so long on an f22 because they have no power lol, 145hp in 2950lbs isnt fun

 

i know someone who used to have a h22 accord with an f22 tranny and he could only get 15.5 in the 1320. the accord tranny on an h22 sucks.

 

great

i know a guy a Type R that cant crack 15.5 either, what does that prove? Just that hes a bad driver

 

It's what I figured. I'm slowly getting convinced this is what I want to do eventually when my engine blows up.

 

think about it, it is impossible to stay in vtec from 1st-2nd with a f22 tranny. there is a reason why we lower vtec even with the h22 tranny and rev to 8k rpm on the tach. given that a prelude runs a low 15 stock, i think 15.5 with an accord tranny is fairly accurate for a decent driver.
