F22a1 to H23 Intake swap

I'm trying to get some help on upgrading my f22a1 prelude S dirt circle track racecar. We race in a 4cyl stock division class which all components must appear stock, so aftermarket parts are out of the question.

I have an f22a1 with auto trans(sucks) but thats all we could find cheap. We also bought a 92 si with a h23 that is locked up for parts. Im gonna start removing the h23 from the parts car this week and hopefully get it on the f22 by weeks end.

I'm needing more clarification on the IAB's and black box to run them. prelude Do I need one, or will vacuum work if we are mostly wide open all the time. Also, will my pt12 ecu work, or should i move to a differnt ecu, and do you know if that will work on a f22 prelude? Do you have any other cheap upgrades also? I have the cat, etc back removed, and all belts removed as we only run 12 laps at a time. I heard a f22a4 manifold will also help.

Any ideas would be awesome.

whats wrong with a front wheel drive dirt track car. if you had and LSD tranny it would be good. you would pull yourself through the turns rather than just spinning your wheels. its just a different style of driving

actually the prelude works well as its a fwd OHC beginner class and stock at 125hp is not bad. We got the car wrecked for a few hundred, and put some in it.

Anyway, does anyone have any idea on the intake from the h23? Will it work with the stock pt12 ecu, and is there a better option for the f22a1 than the pt12ECU? Will the pt14 from the h23 work on the f22a1?

Also, should i leave the IABS open on the h23 im all the time as we are usually wide open, as my computer will not open them? Has anyone ever disconnected the coolant lines and bypassed the im to keep the heat down?

you can remove the IABS's if you want it wont do any harm just hurt your low end power but as you said you are wide open most of the time so its fine

You can actually use the whole H23 head on the F22 block. Look around honda-tech and cb7tuner for specifics since no one here has ever posted much on it.
