B5 S4 vs. B6 S4.....

[Jon_Rhea]

Ok, a few questions. First what is the moddability of the two cars?? Which one is easier to mod and less expensive. What is the max hp you could get out of a B6 S4?? Any help would be great. TIA!!

[JMG]

B5 is more moddable just because of the turbos, but I beleive the new V8 is more reliable

[G_A4]

the b5 S4 has a V6 bi-turbo engine and that mods on this car is endless. bigger turbos, chip, you can make more HP on the B5 then you can with the B6. way more.
B6 S4 is a N/A engine and a V-8. pretty much thats it. as far as modding the B6, exhaust with downpipes. the B6 is a heavier car too.
out of the box the B6 has 340HP vs. the B5 has somewhere in the range of 285HP i believe.
B5 would be more expensive to mod because their's really nothing to mod on the B6. bi-turbo is the way to go.

[Jon_Rhea]

So in the end, a modded B5 would hand it to a "modded" B6 as there isn't really that much one can do to the B6?

[bbaudi382]

the b5 is just easier to mod. but if somebody went all out with a b6 im sure it would be faster than a b5.

[astris]

I heard there is a supercharger in the works for the B6 S4. That alone should push it close 450-500hp. Add exhaust, after cooler, and some tuning, and you have a monster.

I would much rather have a B6.

[bbaudi382]

agreed. when i mean all out i mean supercharger or better.

with the b5 you can just get two replacement bolt on turbos and you're already looking at 350-400hp with the right tuning.

Here is the article I think we are all looking for. It gives a nice little comparison of both. cheers! mike

a SC for the B6 S4...?

where the hell do they plan on putting the blower...?

[Silvant]

takes deep pockets to get that power out of the B5.. jus depends on how for you want to take it.
you go all the way and you are lookin at droppin 20+k to create that monster..
advice of the day.. get your 1.8t to around 300hp and buy a shifter kart.

wow, those boobies are the bomb...

Well said Silvant,

I'm sure you and the B5 boys have seen this vid. It's been around for a few years. I remember reading a post just recently on AW by a B6 S4 guy who says the B6 S4 will take a Stage 3 A4. I just saw this vid for the 1st time yesterday, this is proof how fast a Stage 3 B5 A4 can be compared to the mighty B5 S4 Stage 3 which will destroy a B6 S4, exhaust and intake mods included. Silence proved the B6 A4 is capable as well in our T28 vs. M3 vid. 4 bangers rule!!!

To those who haven't seen, check these two drag races out. The same Stage 3 B5 S4 that barely beats the Stage 3 A4, ties a Viper in the other drag run! If the B5 A4 had the Stage 3+, I think we're dead even! The A4 is the yellow car BTW.

the B5 S4 stock has 250 HP.

I have a buddy whos B5 S4 is easily over 400HP with Rs4 Turbos, fueling, etc. You can go over 500hp with one and the engine can take it. they do have issues at times with reliability. The V8 B6 has a greater displacement at 4.2l compared to 2.7; so right there the V8 has more overall potential. Getting their is costly and drastically reduces the relaibility of the NA V8 when adding a forced induction aftermarket system.

The RS6's 4.2T with stock turbocharging is the way to go out of the box. . . wait till the B6 RS4 comes out.

It should be the a machine.

a SC for the B6 S4...?

where the hell do they plan on putting the blower...?

this has already been done, and is quite impressive to see. I have pictures of a black one with a sweet supercharger attached. I haven't really heard anything recently about it though. It was a European company that was engineering the equipement.

Exactly my question, heh. I have a friend with a B6 S4 and everytime I look at his engine bay, I wonder the same thing. Everyone's always talking about how IF it's s/c'd or turbo'd, it'd be crazy, etc etc, but I still can't figure where the HELL they'd fit it in there.

look above

I thought that B6 S4 in your sig. was yours??

No no, I saw it, I just didn't think that was a working model. There's been little to no buzz about it, other than "someone's workign on it..." I'm interested to see how that'd work, though. Wonder how the block itself would hold up...


that is my S4 in my sig...but it's a B5 my friend

I've heard from a few sources that MTM, ABT and OCT have one coming very soon. I too wonder with the Hi compression V8 what they'll do to lower it in order to safely add boost. The E46 M3 has a SC that puts out 440HP, around $8600.

Although still very fast the B6 S4 needs 400 HP to really move all that weight, over 3800 lbs, the SC would easily do the trick.

ah, good deal . . . didn't look at the tails close enough.

I haven't heard anything about that kit recently either. If I had the money to SC a B6 S4 and own one . . . I'd just get the eventual B6 RS4 instead.

according to that drawing they have the drive pulleys on the front of the engine, but they are on the rear side...

No, just the front, the rear part is the intake track.

[Diesel'S4]

but the actual drive pulleys are really located on the rear of the engine on the S4...

the drawing shows different...

i would CRINGE at the price tag on that thing... very intruiging though... 400-550hp...?

I didn't know that, I thought the pullies were on the front, my bad. You're right, the price tag will probably be over 10 grand! Mark's right the RS4 would be the way to go. Or maybe the RS3 if they ever make it here.

[Mark]

there are cam chains in the back of the V8 engine . . . I do not know if this is how the unit is powered. A hard install if that is the case though . . . more $$$$. Also; perhaps a bad idea?

Who knows. I'd rock the S4 stock and would be happy as a clam.

yeah, me too...

that kind of modification will be nothing but trouble anyhow, and would most likely just kill the ownership experience...

of course you would be able to say i got a boosted V8...

[i_eat_staples]

AMD recently announced it will be making a supercharger for the 4.2 s4

couldnt find the actual announcement post but this one refers to it

http://forums.audiworld.com/s4b6/msgs/113623.phtml

i bet nothing quite sounds like a SC'd v8 s4 w/ non-resonated milltek full OI

[JetBlue]

AMD is claiming 400 HP from their chip, exhaust, and intake. That is about as far as you can go with the V8 right now and no one has confirmed this on an independent dyno.

[Silvant]

stg3 and beyond for a B5 S4 can be a $60k plus car, with the B6 S4 you're starting at $50+ and then looking at adding $10k just to the engine if
any of these superchargers ever come out.. then ad wheels, suspension etc .. . . another ride around
$70k.. and to think about the B6 RS4, throw out some prices, its gonna be high. you guys seem to talk about these things pretty easy. if you can afford it then great and more power to ya, im jus laying out the reality here.
