Any recommendations of what i can do to this motor to increase performance? Already have a cold air intake installed.

Pretty much anything that can be done to an F22A1 or F22A6.
What do you want from it? Easy mods would be the F22A6 intake manifold, cam, and ECU. Adding a 2.25" mandrel bent exhaust system with a free-flowing muffler will help. If your intake is a cheap one, upgrade the filter to AEM or K&N.
To get more extreme, check out www.bisimoto.com. Bisi is pretty much the authority on making the F22 an amazing performer. That, or research building a turbo kit. There is an exhaustive amount of information on that on this forum.
Quite honestly, this forum is based solely on cars that come from the factory equipped with the F22A motor. There is probably more information around here on improving your F22A than you can even comprehend! Take a look around!

Yeap, pretty much what deeve just told you. You have an a4 like me. Id say the easiest upgrades right now could be to change out your header. Go for a stainless steel or ceramic header. IMO ceramic though, cause those usually trap in more heat, adding power to your exhaust. Also, you have your throttle body you can change out. Theres ALOT of friggin stuff you can do. Use ebay alot, but be sure what to buy. If its TOO cheap, forget it though. Haha, i learned the hard way not to do that. Good luck though and welcome to the site..Comment

a header upgrade on the a4 is something you should worry about after you've done a lot of other things, unless you think a shinier header is
an upgrade and don't care about flow characteristics....and on the 7th day, deevergote rested and called his mom.Comment

So new headers really wont help to an a4? Are the stock headers that good?. O well, so i guess this would be the same with the stock exhaust as well?Comment

OR you can just keep your A4 header, its already 4-2-1! Dont wast your money on another header, upgrade the manifold, cam, and ecu.Originally posted by ex_style90

is the A6 ECU really that much different from the A4? and whats the name of the A6 ECU? I know the Civic ECUs can be chipped but that requires a lot of knowledge and work......will getting an A6 ecu help me out?Originally posted by deevergote%101 stockComment

I was a bout 2 hours away from buying a new header, then i took the heat shield off, and took alook an the f22a4 header. i just thought, "why an i gonna spent $350 on a new header thats basicly gonna be a little shinier and thats it?". its good to hear it was a smart to spent the money elsewhere

sarecho7280 knows his stuff. Listen to him.
The A4 header is good. The DC Sports header or anything under $400 or so is no better... maybe even worse. I'm quite sure that the companies like DC, that make headers for just about every motor out there, never really put a ton of research into the design. You CAN improve on the A4 tubular design, but DC and the other cheapies most likely have not.
Kamikaze is supposedly decent, though I've never seen proof. Bisimoto will be the BEST header you can get, with guaranteed R&D behind the design (Bisi races with an F22, so the research is justified).
The F22A4 and F22A6 are both EX motors... but the F22A4 shares the same PT3 ECU as the F22A1... the low end DX/LX motor. The F22A6 has a more aggressive fuel map. Without it, the other A6 parts won't show their potential. Pair that with the intake manifold and cam, and you'll see some gains. F22A6 intake mani, cam, and ECU, with the F22A4 header, will probably make about 145-150hp to the crank, assuming that all other factors are perfect (compression, ignition, etc...) Fabulous gains? Nothing to brag about... but at 20-25hp over an F22A1, and 15-20hp over an F22A4, it's not too bad for parts you can pick up for next to nothing!

what about the F22A1 motors? can we do the same upgrades (A6 ecu manifold and cam) and expect similar gains? not so much as much, but a little? what model/year did the A4 motor come in? maybe i can grab me a header from the scrap yard haha93' 2dr

Now if i decide to go yard shopping to pick up parts on a budget which car would i want to look for for the a6? i know its budget material for now but better than nothing. what are your thoughts on running a turbo system on the a4?Comment

The F22A motors are EXACTLY THE SAME for the most part. The A6 has a better intake manifold, cam, and ECU than the F22A1 or F22A4. The F22A4 has a better header than the A1 or A6, but is otherwise pretty much identical to the F22A1. The A1 and A4 ECU are both the PT3, whereas the A6 is a PT6.
Keep your A4 header, get the A6 intake manifold and ECU. The cam is a little more involved, but it will also give some gains. I believe the manifold is more noticeable, though.
Another common upgrade is swapping on an intake plenum and throttle body from an H22 or H23 (well, the entire H23 manifold will work... not the H22 one though. Either plenum will bolt to the F22A6 lower half)
As for turbo on the A4, look around the Forced Induction portion of this website for more info on that. Turbo can be done very cheaply, or you can spend a fortune. If you know what you're doing, you can keep costs down... however, there is a point where you truly get what you pay for.

So which would be more beneficial, the a6 intake or the h23?Comment
