Hey everyone. I’m new to the Honda world and I’m going circle track racing! Dirt for now. I have a 95 Accord EX with a F22B1 engine automatic.
In my class I’m limited on what we can change. Engine must “appear” to be stock. So no putting DOHC heads on a SOHC block. I’m finding out that with the f22b1, most guys put the H22 heads on but I can’t do that. NOTE: Most parts will be from salvage yard and nothing high priced!
Can I get some direction or help on what other heads will fit on a f22b1 block and an intake manifold that is designed for a little better airflow. Even if it’s a small power gain, tenths of seconds matter so any added hp or torque will help.
thanks in advance fellas

 

If it has to appear stock then your "stealthiest" option would be an F23 head/cam and F23 intake manifold from a 98-02 4 cylinder Accord. The F23 head is a SOHC VTEC head just like the one you have but it comes with roller rockers and a slightly more aggressive camshaft. It would be a direct bolt on for you. The F23 intake manifold is a much better design than the early F22Bx design and has a larger plenum and more optimized runners. The intake manifold does require some small modifications to be compatible with your chassis though.

I would say a full F23 swap would be your best bet but with the block identification stamp right on the front, it would be very easy to tell it was swapped.

 

Thanks for the info Aradin.
Yeah I’ll have to keep the f22b block for sure. No changing that. But the heads and intake mani I def want to change. It’s FWD dirt for crying out loud lol. So they may not look at those.
I’ll be looking into those heads and intake I’ll be getting(used).
You said small modifications to the intake and I’ve seen some videos similar swaps but not exactly sure what mods they made(they were explaining as the engine was running. You happen to know what some of those mods may be exactly?
Is it possible to re flash/program the stock ECU for a LITTLE more power as well? And without costing an arm n leg?

 

Thanks for the info Aradin. I’ll def have to keep the f22b block. I’ll be looking into the f23 head and intake mani. You said small modifications and I’ve seen some video on a similar mod but they were recording close to the engine so ya can’t really hear them. Would I have to do anything to the ECU and would swapping to the f23 heads cause and interference with the pistons?

 

The F23 and F22B1 heads are pretty much identical. Really if you didn't care about the roller rockers and didn't want to open the engine you could just swap the F23 cam into your current head. Shouldn't need any ecu modifications.

For the F23 intake manifold, you need to convert it from a 3 wire IACV to a 2 wire IACV via an adapter that can be found online. Vacuum and fuel lines will require some minor rerouting IIRC. You may need to modify your throttle cable bracket. It's pretty easy.

 

Aradin! This has been amazing help. Thank you soo much!
Ill try to keep ya up to date on the progress!
