f22a6

[kwh924]

I know you can add the F22a6 camshaft on a F22a1 or 4 and get a gain but do i have to use any other parts for it to work or can I just throw in the camshaft by itself

[91 EX-R]

you'll probably need to use the ECU off of the A6 for it to run properly but it might not be necessary. i dont know for sure.

Do u have a A6 cam rite now?

If not u can get a delta 272 cam, which is an upgrade for our CB's , and u dont have to upgeade ur valve-train.

if you want to keep it OEM, get the cam, intake manifold and ecu. You can do the H22/23 plenum/TB swap as well (search the DIY forum for that) and find a f22a4 in the junkyard and grab the header from that (I just got one today for 23 dollars.). Or just get an H intake manifold.

I was under the impression you should get tuned if you do a 272. I got a Cam out of an A4 today just for that purpose, so i still need to research the regrind more. I am considering bisimoto's regrind as well, its more expensive but he seems to be the premier expert on f22ax motors. so, we will see.

i was just gona ask the same thing...i wud also like to know more about the delta 272 cam. would the ecu need to be tuned?

[Yossarian]

I'm not sure that it NEEDS to be tuned. It probably should be though. The only real documented 272 build I've found so far is Cisco's red project (well documented, anyway). He did some extensive headwork though. I dont feel its worth shelling out the cash for a good PnP job. Looking for more horse like that, the money would be better spent on higher compression pistons or starting an H22 fund. I think his goal was max horse on 87 octane though.

At any rate, for the money doing the A6 cam, H23 Intake manifold/Throttle Body and the A4 header, plus and aftermarket catback will net you decent gains, all OEM and easy to install. Pretty much just bolt on. Since you need a second cam to send out to get a regrind anyway, (unless you dont mind letting your CB sit for a while.) Use the A6 while your smaller cam is getting worked on, while its out do some research.

Oh, you do need the ECU from the A6 donor, for the IABs to work and the fuel map for the wilder(ish) cam.

Ok mmy car has the f22a4 engine so I'm pretty sure I've got the header. So where can I find the Delta 272 Cam and should I run the F22A6 ECU on it? Also will it work with my AEM F22A Cam Gear?

The cam gear is useless for you right now. you need f22a6 or an h23a intake manifold and the a6 cam to make use of the a6 ECU. as for the delta....google delta cams.

.

from my understanding, why get a big lobe cam (more racing appl.) and not port your head?? yeah a bigger cam will give you more power even without the ported word on the head, but it will run at full potential with a ported head with the delta cam.
just imagine putting the a6 camshaft on without the other mods. you MIGHT feel a 2hp ( ) increase, but without the intake manifold and ecu, it is worthless. that's just my opinion though buddy. but I understand where you are coming from though, most of us ( me too) don't have that kind of money to throw into a motor just not yet. It's algood bro.

for the delta cam....PM ceelooboob. hes got one for sale

Porting and polishing is one of the last things you do to a motor. Cam, Pistons etc. will help you better use the airflow you already have. Once you outgrow that flow, then you need to open it up a bit more.

Higher compression, cams, intake and exahust work will often net you better gains for less money. And with those mods you can get more out of your PnP.

ok guys, your both right, but iv noticed a few things were left untouched, high compression comes with a pretty hefty price, you cannot simply throw a new set of pistons in and call it a day, after that, a6 ecu or not, you will still need a tune, the fuel system will be all out of wack.... its going to have to be updated, and at that point higher degree cams are going to become nessacary, remember, at 720degree rotation, you dont burn all the fuel your putting into the motor now, and at best, JUST installing a cam will catch you a few ponies at the top, but you will be sacraficing fuel econemy, and money in the arguably wrong areas... now my question is why would a PnP be the last thing? or again, arguably not worth the cash? have you ever seen the ports on a F22 head? their absolutly HUGE! i will agree, that porting is probibly a waist, but pollishing alone is in my opinion a very cost effective move, as it willnot add huge power, but it will change the nature in which the motor breaths, there will be a all around benifit, throttle response, low, mid, and high end gains, tq. gains acrost the bored, and will only serve to compliment any future modification... i personaly would suggest he dose a little more homework on his engine, planning is everything, and no one modification alone will be the deciding factor in the overall performance of his motor!
