I'm usually in the Prelude Forum with my H23 Lude, but my friend just got his parents Accord LX and he didnt even know what the engine code was, so I checked it out and it's the F22B2. I don't know much about SOHC, but is it possible to slap a F22B1 head onto his B2 block? Or is the B1 DOHC? I don't even know...thanks

 

yes it is possible. the f22b1 is the 5th gen vtec accord motor, from the 94-97 accord EX. its SOHC. you would need the vtec ecu and to wire the vtec up. just make sure the OBD #s are the same to save yourself a hassle.

 

Also, it would be wise to get the EX header which 4-2-1. It will give a little bit more Hp over the LX header.

Lots of good info. It is for an a1, but it applies to a b2 as well.

 

the lx header would fit the vtec head?.....doesn't make sense to me. He would have to replace the lx header with the ex header to fit proporly

the ex and lx exhaust manifolds are the same except the ex is try-y (4-2-1) and the lx is 4-1; and the o2 sensor is on the primaries on the lx and at the very bottom of the secondary pipe for the ex. other than that the ports and stud holes are the same.
all that has to be done for the lx mani. to fit on the ex head is you have to extend the o2 wires, very simple.

 

Does the F22B to F22A have problems?

just one.....it doesnt make any power, lol.

 

That's a pretty big problem

 

F22B head ports spacing / manifold bolts are the same thats why ex can use lx header and vice versa just a design and slight power output difference.

they make some power when you slap a snail on

 

NO YOU CAN NOT...the B2 ports are spaced
0 0 0 0 and the B1 ports are spaced
0 00 0...it's NOT a do able deal...you NEED to buy an EX header if you plan on swapping heads...

 

On the 94-97 Accords the exhaust manifolds are ALL interchangable. On 90-93 they have different patterns. But if you're using a b1 head, then any 94-97 exhaust manifold will work.

This is not true. The exhaust ports from the two different heads are the same. However, the exhaust ports from a f22a are o o o o. b1 and b2 are both o oo o.

 

misread the question...my bad

 

ok so would i have to do anything besides bolt the vtec head up and run some wires for the vtec ????? i have the whole top half of the motor and ecu. no one is being very specific on what needs to be done for this project to work. i have tried several different forums and they all lead to pretty much what the one before was saying

 

The work/money isnt worth it IMO. With the money it costs to buy the head/ecu/wiring, he could be well on his way to a non-vtec turbo setup, or just tell him to save up for an h22.
