F22A4 Air Intake Conversion

[StuckeyOG]

Okay so I would just like to start off by saying yes I have used the search function and read up on this thread. I would just like to receive direct input from others for my situation specifically, thanks.

Basically, I have an all stock 5 speed 91 accord with only an aftermarket air filter on stock tubing. I want to get a little more power out of it and was planning on going to the junkyard and getting the IAB, Camshaft, and ECU off an F22A6 and then throwing a H23 intake manifold and the F22A4 throttle body. Am I missing anything? Simply looking for a smooth ride and increase in power thats not going to put a huge amount of stress on the motor when I decide to push it to redline haha.

What thread have you been reading? The F throttle body is smaller than the H23 throttle body. You're going to also need F22A6 or H23 runners. The H plenum will not bolt up to your stock runners.

i thought h23 intake manifolds generally come with the runners, am i mistaken? and thank you for letting me know, so get the H23 throttle body and rollers and im good?

Sorry, I thought I read plenum, not manifold. Yeah, you're gonna want the H23 throttle body.

This is everything I plan to buy online, everything else is coming from the junkyard unless anyone on here has old parts they're trying to get rid of haha. I'm guessing this OBX intake manifold does not have runners though? Anyone know where I could find some online maybe?

Still considering what exhaust and header combo to go with, gladly taking opinions on what's good

Careful...There's no discussion of buying/selling in the beginners section.

That OBX has runners attached, and would negate your need for the black box, and possibly the ECU.

That OBX manifold is not ideal for your setup. Its best suited for force inductio.

To be honest I'm pretty confused what direction I'm being pointed in. So far all I've been told by anyone is to not buy what I plan on buying, I'm new to all this thats why I posted in beginner performance sorry if I come off as inexperienced, it's because I am. What parts do you more knowledgeable CB7 tuners suggest I purchase? Would appreciate as much as guidance as possible in the matter. Thanks guys.

We would suggest what you originally indicated you'd be purchasing. An entire H23A1 intake manifold with the IABs as well as the black box underneath it and perform the necessary wiring to get it to work.

Also, the F22A throttle body isn't just smaller than the H23A1, it's a different bolt pattern. You can't put the F22A throttle body on the H23A1 plenum.

I think what the members are trying to say is stick to a stock H23A1 intake manifold and throttle body, and not buy the OBX-R H23 intake manifold from your links.

These are the usual lower budget F22A1/4 engine upgrades;
Complete OEM Honda H23A1 intake and throttle body
F22A6 Camshaft and
PT6 (F22A6) or P12 (Prelude S) ECU

Thanks for breaking it down for me man, I know what everyone was trying to tell me now. I'll definitely keep it OEM in that case Thanks everyone!

I found someone who said they're willing to sell me their intake and throttle body including injectors and sensors for 100 dollars, does this seem like a reasonable deal?

If I purchase this what else am I going to need to get my f22a4 all bolted up to the IM/TB? Just the F22A6 headers and ECU? I'm confused as to where the IAB and black box is attached to and from who I should expect to buy it from at the time? Would the person I get the headers from have it or the person I plan on getting IM/TB from?

Clear pictures definitely would be appreciated if anyone knows where to find them. Otherwise please let me know ASAP. Thanks guys!

[GhostAccord]

$100 for a complete intake, throttle body, sensors and injectors is a really good deal. What intake manifold is it, what make, year, and what condition are the parts in? Do you have any pictures you could pass along?

You don't need the A6 exhaust, the A4 is suitable for what you are doing. Unless you want to go with an aftermarket header. In that case they fit all PT3 (F22A) heads. If you want to make the most out of an intake and cam swap you will need a new ECU. If all you are going to be doing is some bolt on parts then the PT6 or P12 would be your best bang for the buck. If you plan on going further with your build. You could go with a tunable OBD1 Honda ECU.

As far as the IAB and it's control system, that should come with the intake manifold.

just to help out the OP. youll love the h23 intake mani. and on the F22a4 you can delete the iab butterflies and no have to worry about the ecu. just pull all the parts out of the mani and plug the holes. and you can stack 2 gutted iab plates for a little more power. youll need longer bolts of course. but heres a pic to kinda help the basics of the intake mani.

Okay well ive found another person who has the oem h23 intake and tb they said 60 dollars and the other guy who said 100 lowered it to 80. My only question now is whether or not I should commit to the conversion when Im burning a quart of oil every couple weeks and have a idle surge problem? I plan on attempting to address the idle problem soon by cleaning out egr and other valves etc. But wont changing the intake mani/tb and installing a6 camshaft and ecu potentially change my idle and air fuel ratio anyways? Would that negate my efforts to clean and fix everything? Would you personally just throw all that combo in there and then start cleaning everything out/adressing why it burns oil and idles strange at times?
