[KeeleDesign]

sorry you so uptight i was just asking a question but i see you like to be rude and think you are the best. so whatever

rotflol!!!!!!!!!

the p12 is out of the prelude, right?

[Shadow1]

ok keeles. back on topic

the p12 is out of the prelude, right?

yes the p12 is out of the prelude. i cant remember what year tho. its somewhere on this thread. i think with in the last few pages. but its the prelude that comes with the f22a1 motor.

sorry guys for my words last night. so anywaysi see to upgrade to the a6 ecu on the a1. if i do that first how much will that help by itself or should i just buy all the parts togther for the 30 hp

[deevergote]

The A6 ECU by itself won't do much. Without the parts to justify the different fuel map, it might even decrease performance (which is one concern I have about the P12, as it wasn't designed to work with the A6 and H23 parts)

[jdm92_accorn]

so the p12 would be good on a stock a1 with i/h/c but when you change the cam and intake mani. the pt6 would better.

cool i bought the car from my friend(wifes old car) and the is a p3 ecu in the trunk so i quess i need to look and see which one is in it now

[accordtypeR]

Hmmm thats great info deev...

[90ACCORDLXGUY]

Great info Deev, next time I go to the junkyard Im keeping my eye for this stuff

[breeziebabyyy]

If you want to make power for little money... hit up a junkyard, or www.car-part.com

Look for:

F22A4 header - $15 (90-91 Accord EX)
F22A6 camshaft - $25 (92-93 Accord EX)
F22A6 ECU - $25
H23A1 intake manifold and throttle body (from a Prelude SI, 92-96 I believe) - $45
F22A6 IAB "black box" (to be able to activate the secondary runners, the intake air bypass, in the H23 manifold) - no price listed... probably $10 or so.

The prices are from my local junkyard, which is average for most things.


Your stock F22A1 engine's horsepower rating is at 125. The F22A6 parts alone will bring you to 140. The A4 header should get you to 145 (the ONLY difference between the A1 and A4 is the tubular header on the A4... which is superior to both the A1 and A6, which both have cast manifolds) The H23 intake manifold and plenum should add another 5hp or more... no exact figures are set for that.

If you do the camshaft, which isn't a HUGE part, but it helps, you're going to want to replace all the gaskets and seals you come across... good preventative maintenance anyway! That'll be another few bucks... but not a whole lot.

Get a cheap short ram intake. Have a muffler shop slap a 2.25" system for you.

The stock Honda parts would run about $120. A cheap short ram can be had for $50 or less. Exhaust... depends where you go. I paid $450 for new piping, cat, and muffler. You can probably get away with keeping your stock cat. Find a cheapie muffler on ebay, maybe a used one. Pay for piping and labor only. $200 at most for everything, I'd say.

So... that's under $400, and you can gain a minimum of 30hp... that doesn't include the intake and exhaust gains.





These things have been said over and over again... but I figured I'd make a post stressing just how simple things were!

I was told I needed a head for my a6.. can I put an a4 head on it or it has to be an a6? None of the junk yards here have any a6 motors period lol they are all a1's. I did find ONE a4 motor but I was like wtf!!

[deevergote]

The A1 and A4 head are exactly the same. And yes, you can put one on there.

What's wrong with your A6 head that you need a new one?

[lokuputha]

the only thing i don't like about it is driving on the highway. 4000rpm's @ 80mph in 5th. later.

lol...I know exactly what you mean, I did a 1500km trip doing that with my F20A DOHC tranny, seems to have gears as short as the H23 tranny. good times

great thread Deev, this is a definite must for the SOHC builders.

ok sorry if this is a little off topic but u guys seem 2 know a lot about the a1 to a6 swap.ok i have the pt6 ecu instaled and i am waiting for new seals and gasket kit 2 install the cam and i/m but to control the eacv wich some call iab i connect the pnk wire with blue stripe into pin # 17 in the longer of the 3 harneses but where does the other 1 go i read something about a swtched source i wonder if they meant a switched source like the red wire for cd player? not 2 sure on this but once i figure it out i will run some tests 2 make sure everything works fine before installing. any help will make my 30hp a reallity for 100$.

to the black yellow off the distributor, or another 12v source

The H22's AIB circuit that opens the short, high-rpm runners in the intake manifold also gets added by tapping the black/yellow wire from the H22's plug to the same color wire that goes to the distributor in the Accord's harness. This simply supplies power to the AIB solenoid. The pink signal wire goes from the AIB solenoid back to the subharness/ECU at pin A17.

oh wow geez thx for confirming that with a strong answer i had a feeling that it hooked up like that but wasint 100% sure thx i will run a function test as soon as i get a descent day outside and again thx
