How to make 30+hp for $500 or less... (DX/LX F22A1 only)

[owequitit]

Ok, then what I have here is from an A6?
Is that correct?
So this would be more beneficial then the stock a1 that I have?
And is it really, really necessary to re-istall the heat sheild? Because I dont have it.
Unless of course the a1 heat sheild fits back over the a6?
And I've read every post in these 12 pages .. very, very awesome info,
specialy the ecu stuff .. I have intake, (a6 header) and exhaust ..
Maybe look into a re-chipped ecu ..

That is indeed an A6 upper half. You can leave the heatshield off, but it will raise your underhood temps by quite a bit.

In terms of quite a bit ... compared to a DC Sports header (which is steel)
and ceramic coated .. about as much .. or more?
I'm just trying to find out by how much more the underhood temps could be.

Would the a1 shield fit? (I dont believe it would) just looking at it, it looks like .. no, lol.

I never measured exactly, but it is definitely noticeable.

I would say about the same as a SS DC header, and more than a ceramic one.

I think im going to try this when I get my next cb . Ive never seen this tread before.

[lx-accord]

great info guys keep it up!!

[ohdengitzpat]

just wondering if the f23 IM and TB would work like the h23 ones.

No. The F23 IM is not a direct bolt on for the F22Ax.

so if i where to create "in other words" an a6

a6 intake, cam, and ecu would do,

what about the rocker arm assembly, does it even change?

what bout the springs, are the a6 stiffer (dont assume plis)
i
f u get an 150k miles cam, and throw it an a 100k mile head,
wouldnt bearing clearences on the cam be affected?

header would be an a4
and YES PEOPLE the IAB's

would that be it ?

[CB7Man]

Grab a P12 ECU and get a RPM Switch
Put the IAB's to the RPM Switch and let the P12 do the rest
Thats what I'm doing anyway
Well that and A6 cam, A4 Exh.

[deevergote]

The P12 may not provide the same gains with the A6 camshaft.



The A6 valvesprings are a different part number than the A1 and A4. Because the camshaft is a wilder profile, it only makes sense that they are stiffer springs.

The A6 also has a windage tray (not listed in the initial parts list)


The A4 header may not be a full 5hp over the A6 cast manifold, due to the similar design. The tubular design of the A4 manifold is technically superior to the cast A6 piece, but the potential gain is unknown.



As for a 150k mile cam... that's 150,000 miles of friction on that metal stick. They do wear.

[PR CB7]

so technically
sometimes the valve train upgrade
aaint worth it,

cuz if u telling me that the springs are stiffer
then to make the cam work i cant use weak springs,
also if the cam is worn the if will fuck uup the bearing journals on the head,
making the cam not worth it

[deevergote]

I didn't say that at all.

[PR CB7]

I didn't say that at all.

i know u didnt but im just saying, its like taking rods from antoher engine and JUST putting them on ur car, both engines will not wear the same,
and u'll probably have different bearing clearences, same with a cam,
it aint gonna stop me from throwing the cam, but if u think bout it
some people will not,

cuz they think everything is bolt on, they'll assume, EVERYTHING IS...
BOLT ON,

[deevergote]

It's bolt-on, sure.

But used parts are used parts. There's a tradeoff. It won't damage anything, it may just not work to spec.

A6 does have different intake and exhaust valve springs than the A1/A4 motor. Interesting how the more we dig into these differences, the more we find.

Here are some color designations to tell the differences between springs physically:

A6

INT - blue
EXH - green


A1/A4

INT - yellow
EXH - orange
