so i was wondering if i can take the V-TECH head and intake manifold of the F22B1 and put it on my F22B2, im aware that ill need other parts to successfully acquire V-TECH power. so is this possible? what other parts would i need?? please help good sirs and thanks

 

Im pretty sure this has been answered in your last thread about looking for a new engine....
Try reading all 3 pages of advice that people gave you there..

PS. that plan is a waste of time

 

I've heard it's do-able but never seen it done myself.

 

Yes it is possible.

You would need the P0A VTEC ECU and you will also need a couple feet of wire to wire up the VTEC solenoid and pressure switch.

In my opinion it is a waste of time for 1-2 hp. The older 90-93 F22A* non VTEC heads would be a better gain. Even in the MPG game.

 

Yes, I actually just did this myself. My car needed new heads anyways so I figured why not. You will need new timing covers, Timing belt, some wires and ECU pins, as well as the ECU. The only thing you need to do is remove the oil restrictor from the block. Just bolt the heads on.

 

waste of time? i see, how can the non-VTEC head give more power than the VTEC head??

 

i looked through it but didnt actually read anything about using the heads and wat not

 

From what I read, the Non VTEC head flows much better than any F22 SOHC VTEC head.

 

The F22A6 is rated for pretty much the same crank Hp as the F22B1. Give or take 3-4hp. The port geometry of F22A head is more of a straight through design. Allowing for better flow and taking to modification much easier. Besides the stock SOHC VTEC B1 cam is not designed as a power adding cam, it's based on fuel economy and keeping the lower end tq.

 

Otherwise go with a Bisi Level 2 VTEC cam. Mine pulls pretty nice when I had it on my old B1.

 

so in ur opinion i should look for a F22A head instead??

 

If you are looking to add power, Yes!

 

sweet! thanks man. is that head a direct fit or are there mods to it? just wondering

 

IIRC it is a direct fit. You should also pick up an F22A6 or H23 intake manifold and throttle body. Personally, I would go with the H23. You may also have to do some shopping for a distributor, depending on what year Accord you have.

What year is your Accord, this will make a difference in what distributor you use or how it will need to be wired.

 

Incorrect. The non Vtec F22b2 head does not make more power, the port design is the same as a B1 head.

The F22a head has the potential to make more power, as it has better flow numbers. Good for n/a builds and cams. A simple head swap however, and the b1 heads will make more power.

F22a heads are not a direct fit to the B engines. the water pipe needs to be replaced. You will need a new intake manifold as well.

 

No one said that it did, we are all in agreement here that the port design of the F22B1-2 is shyte compared to the F22A*.

So the B1 head alone will make more power than an F22A6 head. Please show me a dyno where a stock F22B1 makes more power than an F22A6.

Also, Whether your talking boosted or N/A a better flowing head usually equates to better performance. So why waste your time with a poor flowing head when a better one can be had for cheap?

The head itself is a direct fit. The water pipe is not connected to the head. It is connected to the intake manifold. Thanks you for adding it to the mod list though. It's a $10 salvage yard part. It's allready been noted that the intake manifold will need to be swapped as well.

Oh I forgot one other thing that will be required. The exhaust manifold will have to be swapped. F22A* = 0-0-0-0 vs F22B* = 0-00-0. This is just one of the keys to the better flowing F22A*.

Beer:

 

straight off the honda website.

F22B1 rated 145 HP 147 tq

F22a6 rated 140 hp 142 tq

Both stock. Which is what we are comparing.

Also, I know, but nobody said it didn't either. And I wouldn't want someone to run off and get the wrong heads to swap onto their car because nobody specified there is a big difference between the two. I have looked at all three heads. I have an F22a6 in teardown in my storage, the original F22b2 heads from my car in the car port, and the F22b1 heads now in my car.

I will tell you, that with the F22B1 heads, the car is lively, as are the Cb7s with the F22a6 (I have driven both).

However, one thing to keep in mind is depending on your state and their inspection laws is that it may be illegal to swap in a motor that is of older design than your chassis. ('92 F22a6 into '94 chassis)

Ah, and for the water pipe no it is not. It is however, put inside the thermostat housing. Which is bolted onto the intake manifold as you know, which is not only different, but bolted onto different heads. I know where the water pipe goes to. I have changed a head gasket on an F22a6. Taken one to bare block, an F22b2 to bare block, and reassembled it as an F22b1. Which is now in my car. Running. The way it should have been, after two professional mechanics failed to fix it.

They have different part numbers as well.
F22a6: 19505-PT3-A00
F22B1/B2:19505-P0A-000

 

i have a 95 accord 2dr. i was planing on jst getting the F22A6 intake but if u believe the H23 is better then i shall consider that =D. i was also aware that i would need to get a matching header as well, so thats already in mind

 

Yes and as mentioned above you should also add the thermostat housing and rear coolant tube from the F22A*. If you get the head from a junk yard see if you can get the thermostat and tube at the same time.

 

Yea if anything i was jst gonna buy that new since i work at pep boys haha. Yea im at a junk yard and i saw a F22A1, F22A6, and an F22A7,
