f22a1 with a vtec head put on?
will it help on more power?
seen it done on civics

[pedroalcala]

My friend, this has been coverd alot of times.....just search for it (hint: is on the top right hand corner).....there are really no significant gains out of that....if your going h22a, h23a vtec, or even f22b1 vtec head, DON'T DO IT!
The f22a1 head with just a little porting will outflow any other head even the h22a heads.....

You are better off putting a cam on your f22a1 and get power from there....since our f22ax motors are low compression (8:8.1) putting a "Vtec" head won't get you the power you want, if your boosting it maybe its worth but for me it ain't.....just build you f22a1 and get the power from there...f22a1 have alot of potential....and then if you want just boost it!

Na, putting vtec into an f22a1 isn't cost effective (not worth the money) now if you got a spare H22 or H23 or F22b1 head laying around with no block then go for it the gains aren't that great but compared to the f22a1, you'll enjoy it more. just look around, there's info here on the methods to change to a different head using the same block. Look in swaps!

The SOHC VTEC heads are inferior to the F22A head. The DOHC heads are as well to a point (their strengths lie elsewhere)... but the F22A's low-compression bottom end makes these a bad choice as well.

If you want VTEC, swap in an H22A or F20B. Don't bother with the SOHC, and don't bother with a headswap.

Oh...My...God...

SEARCH, ALL YOU HAVE TO DO IS SEARCH!

This has been covered soooooo many times. Go to the beginner technical/performance section, click on the search bar, type in VTEC head swap. Easy as that.

But I will still answer the question for you.

NO, It is a bad idea. It provides no performance gain. It is a downgrade.

Thank you... you'd have been banned for a week had you not at least attempted to answer the question... However, I answered the question in considerably more detail already... You REALLY don't need to flame anyone in this section.

Sooorry, didn't mean to start flaming. Long day at work. I apologize to the OP, but yea, the VTEC head is poorly designed compared to the F22a. I would still do a search if I was you, read up on it. It's still good information to have in the back of your head.

Hey LyvvRacingCB7. If you want to get more power from your F22a1 search for builds and performance mods for it. This forum has an incredible amount of info on this. I am doing a lot of research on building my F22a1 and I have really learned a lot right here both what to consider doing and what not to do. Just use the search bar and start reading. If you don't find what your looking for try different search terms. Also notice that the right side of the screen shows what forum the thread is in. I won't bother looking at a thread in members rides if I'm looking for info on cams, IM's etc...

Good luck bro.

Good advice.

Browse through different threads about building the F22a. Also, look into swaps if you're interested. This forum is FULL of good information.

It makes me proud to call this place my...home...page.

Ugh. VTEC heads are not "poorly designed." Sure, they may not be the best for max flow or valve angles, but for what they were designed to do, they are great. Sure, they have crappy valve angles limiting lift compared to an F22Ax head, but that does NOT mean they are poorly designed. Honda simply had to make compromises. If the head was poorly designed, the engine wouldn't have been making 200hp back when other companies BOOSTED 4 cylinders were making 180-200.

Exactly.

Even the SOHC VTEC heads are not poorly designed. They are reliable, efficient, and emissions friendly. Exactly what they were designed for.

A VTEC head on an F22A block, however, is not an upgrade. That is all that SHOULD be said on the topic. I really need to watch what I say. I say "inferior" as a shortcut to explaining the performance shortcomings of a SOHC VTEC head to someone who wants to "upgrade"... but they are only inferior for that one purpose (and the one purpose that Honda did not take into consideration when designing them).
DOHC VTEC heads, as I mentioned above, may have less than ideal valve angles and port designs, but they make up for it in other ways. They are also very potent. However, on a low-compression, low-revving F22A bottom end, you lose the majority of that potential. Sure, you could build the bottom end... but if you're going to do that, why not build a proper H22A or F20B?

thx for all the infomation i am grateful to know this site has many helpful member..

[mndude07]

The f22a has more potential than any H series motor. I say potential because harnessing that potential isn't so easy. The head outflows most other Honda heads. I believe that the intake ports actually outflow the k-series....but the k-series exhaust ports outflow the f series. Also, you're cutting the rotating mass in the head in half with a F22a vs a DOHC motor. SOHC is much more difficult to tune though. Also, If you're making stupid high power, vtec is eliminated anyway.

[CB7 Sleeper]

I wasn't saying the H22a or DOHC VTEC heads were poorly designed, I meant to say the SOHC VTEC head isn't designed for a performance gain, more fuel economy than anything.

The F22a has more potential, stick with the Non-VTEC head.

Later.

sorry to be stupid but i have an a4... i could put an h23a head on it????
