Audi S4 2.2t Build

[Aandreaaz]

What are your thoughts on the use fof the cone filter near the hot exhaust, rather than in air intake from the inner wing or low down in the front passenger side grille ?

There is usually an cut original S4 air duct there, the one that goes to the airbox, but this picture is from a car show and the duct is ugly, so i took it away

You can see it on the picture with the gearbox, it lying on the ramp just above

I am assuming the 'sump vent' from an I5 2.5L diesel is being used because of the power output of the engine, but can I ask how this item is better than other aftermarket arrangements.

Just curious to learn - no pressure.

What other aftermarket arrangements are you referring to?
This is an easy and simple fix of the ventilation! Me and some of my friends have had good experience with this setup

[Aandreaaz]

Very impressive work / result. Any more information / method / products used ?

Thanks either way.

I used black leather color/restorer, leatherconditioner and a lot of time

Bought Schrick cams
Intake 260°, cam lift 10,9, valve lift at TDC 0,8,
Exhaust 260°, cam lift 10,9, valve lift at TDC 0,9

Do you / anyone know what the spec of the AAN cams and the 7a cams are for comparison purposes with the specs of the Shrick cams ?

Got hold of a leather interior that I treated, became fairly good

Lovely to see another great C4.

Thanks for sharing. Always good to be able to learn from other's expertise and experiences with these C4 and B series cars.

Hi there,
Way to go brother and will tune in to follow with great interest since I have 1 1994 S4 that I have planned on to upgrade but not so much as you and a lot to learn. maybe can feed off some of your experience as my learning curve.
Best of luck.

Will there be any project thread on it?

[Aandreaaz]

hi are you going to use bigger injectors?

Yep, I have bought Bosch 2200cc injectors

A while since an update now


But does not happen as much in the garage during summer



Well, the intercooler construction went straight into the bin!!
~0.8bar/11psi pressure drop ... worthless

It did not come as a surprise, had almost expected pressure drop, but maybe not so much


But that's nothing to cry about, just to assemble back the old system again!












A fun thing was anyway that I came in 3rd place in the largest Audi meet I Sweden, NordicAudi SwapMeet woop woop






Finished 2nd place last year and still chasing that 1st place





And after the inspection in November (which went perfect), It sounded like the engine had started to knock, much like conrod bearing failure.
So it was just to start tearing out the engine before it got worse, I thought!

But everything looked like new ...! All bearing play was within tolerance ..

Then I discovered when I talked on the phone and stood and fiddled at the power steering pump, that it locks up every two revolutions.

So I tore the whole engine apart when it would have been enough to change the power steering pump.

I should have removed the fan belt before I tore apart the engine. but easy to be wise after the event!






Now I at least know that the engine is in good condition!
Took the opportunity to replace the bearing when the engine is still in pieces



Changing to a 6 speed gearbox, just beacuse I had one laying around





Before I put the engine back again shall I do something about the engine harness so it looks good (not visible at all) and clean up the entire enginebay so that it looks perfect!



Are replacing cams, injectors and intake now when the engine is out, and then do a dyno tune ... need to get over 600whp !!



Will be some reconstructions this winter ...
Need to get a bigger oilcooler, the olitemp is raising fast as hell

Just an AAN intake manifold that has been reworked a bit and had the service channels removed

[s0_big]

Nice What intake manifold are you going to use?
