The S4 intake should fit the heads, but will just make everything else more complicated. No reason to use it over the S6/S8, which bolts right up (except the TB, which may be a different size depending on the year of your A6)
The 40v v8 exhaust manifold flanges are available from advanced automotion for $189. Go wild!
JHM could probably make you up a set of headers, as they had some in the past. However, I am not sure if they are still available.
Oh, and before you ask about the PES supercharger for the C5 A6, it is a piece of crap too.
Dont get anything from advanced automotion…so far the two guys that were unlucky enough to get the flanges had tthen warp the firdt time you try to weld anything to thrm…there cheep and they suck
my a6 is a 2000
i found these two heads…one left one right from eurotrash

im really good with the tig welder…but before i use them im going to make a mold of them so if the do warp i can has my brother make me a set. he does that cnc crud.
Those are A8, not S8 heads.
This thought may be totally unfounded, but I get the feeling you are about to get in way over your head with this car. A lot of the questions you are asking display a lack of basic knowledge about these vehicles. I am not saying I know a lot more, but I wouldnt be ripping my car apart and trying to replace the heads and intake manifold, and make my own headers either.
Maybe I am totally underestimating you, but my guess is things will not end well if you start tearing your car apart.
I would concentrate on fixing the small stuff. I haven’t even see you pull a log with vagcom yet. Have you? It may show some things (like bad o2 sensors) that can be fixed to give your car more power.
But good Luck anyway, whatever you do. Make sure you post pics along the way.
i have not posted a vag log because there is nothing wrong with car. no codes, engine runs smooth as butter as does the trans. only thing it needs is front control arm kit and the intake actuator arms. which i ordered from gruven. i ask alot because i want others opions and insights. i am not familar with this motor like i am with the 1.8t and the 3.0. i know the 3.0 motor like the back of my hand. i did everthing to that 3.0 i had…still have.
hey, in that case, I will be more than happy to be proven wrong. Make sure you post pics of the project, and I will gladly admit I was wrong once we see a half decent dyno or 1/4 mile run.
Good Luck!!!
proven wrong? what are you talking about? i didnt say you were wrong about anything. listen guys im here for some opinions on the belt driven 4.2l. thats all. not saying i know this i know that.
i have been in touch with jhm alot and a certain someone one this site. im doing maintence and cosmetic before i don anything major as there is some power pushin options that will be soon released, as of now i have my lightweight power steering and alternator pulleys and my jhm intake spacers i bought of this site. i also did ecs tuning crossed drilled and slotted rotors front and rear with audi oem pads all around. i will be updating my thread sunday as i just picked up a full rs6 interior.
congrats on getting the rs6 interior, I wrapped my A6’s headliner in microsuede (on a budget lol) and it made a huge difference… I can imagine the oem wrap quality and real alcantara will be even more impressive.
as far as headers, I loved my set, the difference in low end grunt was incredible. but as countvohn (who it sounds like you’ve been in contact with) has said many times before, good headers are more than just pipes, there is a lot of design consideration to get every last bit of power out of them. its a damn shame the jigs for the A6 headers are gone from what I’v heard.
Nice. Stick with JHM and you’ll end up with an awesome machine.

doesnt this kind of look like the motodyne SC???
It does…way too much momey for a used sc kit with the way too small m90
I totally agree and would not buy it…i just thought it was weird because i hear so many people say that motodyne SC wasn’t even real and that the guy just robbed everyone
The guy robbed everyone…that happened…he did have a few kits…ome for thr b6 s4. He actually went to a dyno shootout for the b6 s4 yesrs and years ago…the kit dynoed less then stock…
