RS6 turbo's
 

Ok, I don't care that they don't bolt up, I have a very good fab guy that can make a custom manifold and DP to fit. My question is, are the RS6 turbos configured the same as the K04/3's so that the intake will work or will I need to plan custom there as well? Also, since I think the RS6 only runs 7psi, will it hold up at tripple that boost if needed? Can't wait for RS4 turbo's so am researching other options. Thanks,

Elijah

K04/RS6 hybrids will bring a stock block to it's knees on pump gas, timing-wise...
 

Based on your 7psi comment, you really need to study-up on compressor maps a bit more.

Unless you have compression-lowering mods in mind, I'd just do the hybrids.

Mike, you need to re-read my post and then try to answere some of my questions, thanks.

I read it right the first time and tried to help you...
 

A full RS6 setup will probably not be any better than anything we've done already.

lol

Ok, but from what I am reading the K04 RS6's aren't holding up very well and I
 

would really like to find something that can handle 50K miles or more before needing to be rebuilt. I am very open to sugestion since this a new car to me and i have alot to learn about it. Thanks,

Elijah

I got the very first set of K04/RS6 hybrids, 20K miles and doing great running 500bhp
 

not sure what the problem is from your perspective, 1.45 - 1.55 bar boost and still running great. They are holding up just fine !

Just run the 'brids at sane boost levels and you should exceed your goal.

thats what I like to hear, anyone else?

Ok, next question, where do I find the "brids" these days?

So what's your question?
 

If you want to run them, run them. No one to my knowledge has ever run a straight RS6 K04 (read *non-RS4/RS6 hybrid) turbos so it's hard for us to weigh in on whether it can handle triple 7psi.

People here HAVE run K04/RS6 hybrids with about as much success as you'll see with K04's. If you're saying you want MORE power than that and you have a fab guy that can make you anything then why not go with a garrett or K16/24 solution to be on the safe side?

Make sure to clearance the turbine housings.

Like I said below, I am still learning with this car but since I have an ebay car that came with
 

a blown turbo that didn't make itself clear until I was hundreds of miles away from pickup, I am cought off gaurd and even though I had planned to upgrade the turbo's and pretty much everything else, I was not ready to do it right away, so hear I sit with AW asking questions that people seem to think I'm crazy for asking. I come from the URS-cars where pretty much everyone works on their own car so answeres are way easier to come by when you need help. I just want to upgrade the turbo's and do it right since I have to buy two and can not afford to do it 5 times to get it right like I did with my S4 and S2. Thanks for any help.

Elijah

Thanks, wish I could afford that but I have talked to them and at this point they are out of my
 

price range.

Elijah

Hybrids are out of your price range but you are going to have manifolds, inlets
 

and downpipes fabed up for you? Do you realize the amount of money it's going to cost to have that done? Email Mark@Autospeed and ask him how long it took to get the GT turbos to fit...

dont have the exhaust wheel clipped and they will be ok,trouble is when they try to rebalance...
 

the wheels ,like after clipping the hot side,if anything just get the k04/rs6 with the hotside clearenced

I have a good friend that is very good at what he does and headers and DP's aren't that
 

<center><img src="http://pictureposter.audiworld.com/71531/h4_750_x_562.jpg"></center><p>expensive if you know the right people. Here is a picture of the header he built for my S2.

Elijah

Why not just run K04's? RS6's are asking for more $.

It's not the actual fabbing that would be hard. It's all the engine pulls required to see
 

if everything fits properly. I'm not sure how much bigger the RS6 turbo housings are compared to the K04's. But the K04's are a tight fit as it is. If the Rs6's are much bigger they will need to be relocated which is where you are going to run into problems.

IF you do get them to fit, have you looked into seeing if they will actually work well with the S4 engine? They were designed for an engine almost twice as big as ours with 2 more cylinders. Have you looked into them enough to know whether or not they will even spool well on our cars?

Then comes the tuning. ASP spent a while on tuning the GT car because the boost characteristics were so different from the K03 and K04 cars. How will tuning these turbos compare to tuning other K04's? Lemmiwinks tuning may not be the ideal method to tune the car. In that case you will need to find someone to custon tune the car for you.

These are all things you have to be prepared to deal with, both time and money wise. I'm not discouraging you, but it seems as though you are on a budget. Striking out and installing different turbos that no one else has done before might not be the best thing to do if you are on a budget. And if it doesn't work out, you can't just simply say "welp that sucks I'll just take them out now". You have to pull the whole engine just to get at them...

2nd...why in heck wouldn't you just run K04/RS6 Hybrids'...thats what i'd do

Great, thank you very much for a real reply to my questions...
 

I do realize how tight it is in there and this is why I am here asking these questions. I am fine with just going K04's (if I could find them) for now until I save for something else. I have BTDT with buying too big of turbo's and waiting to 5K rpm to get boost but with this engine I feel the K04's are also to small and so far all I have seen is cold side changes using the K04 hot side. The K04 hot side is tiny and it would be nice to start looking at other options, I was suprised to see that there weren't more who have experimented with this. I am not trying to act like I know anything about this car because I have way to much to learn and it is all new to me but I have STFA and there just isn't much on alternatives to the K04's and K04 hybrids. I am also working with evergreen turbo on ideas and he thinks he can build some K03's to out perform the K04's so that might be a future option as well. I'm just stirring the pot here because it smells burnt and I want something fresh.

Elijah

Find me some!

Find me some in the $2600 and under range!

How about this ------>

yep, 40k on mine from innovative.

Have you checked Audspeed on ebay. Last time I checked he had some K04's
 

he's pretty cheap too. There aren't many turbo offerings out there yet. I think once there are more Garrett turbo kits on the market and people start to peice them together the price will drop and they will become more affordable and a more viable option over the K04's. The RS6/K04s seem to be the way to go at the moment if you want to push your engine internals to the max without completely breaking the bank. The Garrett turbos will be the next step beyond that, but so far we've only seen the very tip of the iceberge, so to speak. They are too new to truely be "affordable".

Will have to have custom down pipes but other then that they will bolt up. Main problem is the lag
 

Lag on the RS6 turbos is quite a bit more then on K04's. Randy Pobst was talking to Pat Socal about it. The RS6 turbos actually came from the Champion S4 WCGT car. He said the lag was pretty bad on the the car.

I would suggest KO4 or hybrids.

and you'll get more then just turbos charged to your card

Thanks, so the turbo's will bolt up to the stock manifold and RS4 intake pipes?

to my understanding, yes. I actually looked into it but the lag issue was not what I wanted.

Did he tell you when the turbo's would kick in? I don't mind lag since I am used to big turbo'd I5's
 

As long as this engine can be reved to 7K+ and the turbos come one by 3500-3800rpm I would be happy.

Elijah

Yea I checked, they are out. Everyone is out that I have checked.

Nice, what did you pay for them?

I will try and ask him the next time I see him.... probably at Infineon WCTC race.
 

But remember Randy has lots of experience in many cars.... so when he says lag... it's probably pretty bad. But in any event I will try and find out. You might want to pose the question to Pat SoCal (lindsey) as he was the one who actually talked with him.

Great, thanks!

I hate to say it, but my K04/RS6 didn't cost that much, matter fact it cost me cheaper then K04
