B5 S4 a dead platform? I'd argue otherwise...

[Max@034]

Little teaser pics for folks before I head home for the day...

One of the prototypes of our B5 S4 Single Turbo Conversion project. Expect more soon.





************************************************** *********************************

EDIT: We are nearing the final release for our production 034Motorsport 2.7T Single Turbo Kit. If you have questions, please do not hesitate to ask them in this thread, or feel free to contact me via the forums or email.

To sum up, we will be offering a few different "Stages" of the single turbo kit to address customers power level and power delivery requirements. A stock motor "K04 style" kit with a smaller Precision turbo will be offered after the 6262 based kit, and then expect a monster 6766 kit to round everything out (for the people who are insane and must make over 700whp ).

Here is a quick overview of "PRELIMINARY" pricing of the basic kit, which is comprised of the major items required (except for intercooler).

OK! Due to the level of interest in this kit, we are posting some preliminary pricing for our 034Motorsport 2.7T Single Turbo Kit.

*** KEEP IN MIND THIS IS PRELIMINARY PRICING AND NOT FINAL ***

Pricing should not change too drastically from this estimate; if anything it may end up slightly be cheaper, but this will give everyone an approximate idea of what the conversion will cost them. Like we do with most of our product introductions, there will be an initial group buy that will be officially announced in June, however we will begin taking deposits for the kit very soon if you want to be one of the first with a production kit.

Please do not hesitate to PM or email me with individual questions, but understand there has been an overwhelming response already, so please be patient if I do not immediately get back to you.

Basic Kit (major components) :

034Motorsport 2.7T Single Turbo Manifold Up-Pipe = ~$750
034Motorsport 2.7T Single Turbo 3.5" Downpipe (top section) = ~$495
034Motorsport 2.7T Single Turbo 3.5" Downpipe (bottom section) = ~$495

Precision Turbo 6262CEA Journal Bearing turbo (4" anti-surge inlet, .82 AR, V-band in/out) = $925

Tial MVR 44mm V-band Wastegate = $395

034Motorsport 2.7T Single Turbo Oil Line and Coolant Blockoff Kit = ~$225

034Motorsport 2.7T Single Turbo Harness Kit (extension, relocation, etc) = ~$65

Grand Total (before any package discount or group buy) : $3350

Intercooler, charge piping, and other components will be added soon. Midpipe is not included in the pricing, but a stock fit midpipe will be $495.



Folks can expect some dynographs today or after the weekend as we finish up tuning. Low boost tuning so far on our terrible California 91 octane gas has been great and things are right where we wanted. Expect over 500whp on 93oct @ 1.5BAR without any meth.

lol - that summed it up for me too

I'm pretty sure that turbo can swallow newborn babies if it wanted to...

hot damn

[falkor923]

I'd get in line! Sure looks like it would be easier to maintain if an issue occurred.

[EErie B6]

its a B5 S4....

There, FIXED!

Uh ummmm......thanks.

Oooooh... nice!

[JDM EJ1 95]

Looks good guys. Love the use of the 2.8 manis. How's that fit under the hood?

[moyenecorniche]

Yikes......" Engage " as J.L. Pickard said prior to warp drive......

[Turbwhistle]

Make the a kit, and i will sell my a4 tomorrow.

"If you build it, they will [buy it]..."


Seriously though, if you make this a kit... and it is near tial 605 prices or less - I WILL BUY ONE.

This looks like it requires you to chop up the secondary firewall. True? I would much rather buy 1 ball bearing turbo and increase the ease of turbo replacements. I do not intend to throw rods in my motor anytime soon... just out of curiosity, what would be a good single turbo for a stock motor (good powerband, 450whp, limited lag, internal wastegate)?

No Trimming of the secondary firewall at all, and the hood closes just fine. Only minor modifications and relocations will be necessary.

My car is the test mule for this setup, you can read more in my build thread; http://www.audizine.com/forum/showth...2-Turbo/page17

Also, the kit has a wide range of performance, especially with the 4" ported anti-surge compressor inlet, allowing it to run very low boost. I would suggest the same turbo for 450whp as I would for 600whp, due to the flexability. We don't want to spill too much more info yet, but expect some good updates soon.

If it becomes a kit for sale.. I'm 100% keeping my car and saving for this.

Hello pretty lady!

[protocol_droid]

Let's see that thing pass cali visual. LOL.

[Polo//S4]

Kit please!!! Then I can stop thinking about a VR swap.

[FlyingGuy]

I'll be honest... That might make me get back into a B5.
Very nice looking setup. Is the R&D cost going to make this setup outrageously priced?

[somebody5788]

Wouldn't mind going this route if you made a twin scroll version. I would love a single turbo with really fast spooling (comparable to K03's) and around 450hp. Maybe a pipe dream but that's what I'd want, Would be really sweet with an EFR turbo up there.

An effective twin scroll setup would require the primaries to extend all the way back to the turbine housing. Not gonna happen with the 2.8 manis.

[DeleriousZ]

"You like this"



Toss a quick spool valve in there and you'll have a fast spooling monster :D

No idea what you mean, but with DeleriousZ's idea it would be as simple as welding on a T4 flange (not twin scroll) and getting a T4 quick spool valve.

Not necessarily! You can just divide the collector rather then merge it into one. This is how big single turbo V8 guys do it.

You can do that, but it won't be as efficient as doing it the other way. I'm sure you know the tech, but for those that don't, it's similar to making an equal length manifold. You want the exhaust pulses to hit the merge point (or in this case, merge point and turbine wheel) at separate intervals to keep a nice constant flow. When the exhaust pulses hit eachother it causes turbulence and other unwanted stuff.

As for the real-life efficiency of the two different styles of routing piping for the divided flange, I don't know what the real difference would be. It's most likely not worth all of the extra effort and cost.

You're absolutely correct. Although it will not utilize the exhaust pulses as efficiently as you would with a 4 cylinder or straight 6. It's pretty much the best you can do. Could you fab up a crazy manifold design that separates and combines each port to give you a continuing flow? Sure! But it would never fit under the hood of the car haha!

Engines oriented in a straight line are much easier to accomplish this rather than V6's or V8's

At least when you keep it divided for as long as possible it helps to eliminate some of the turbulence at the merge.

I've always wondered if it would help by putting an X-pipe prior to the turbine housing some how on that V8 stuff like the picture I posted - then have it go in to a divided housing.

[DeleriousZ]

I believe he means that you need to have the correct cylinders mating together to create the most effective divided turbine housing system, not just the 3 from each bank merging together.

Maybe so, it would still work. But with a quick spool valve all that would go out the window and not matter 1 bit.

Running a y-pipe like that into a divided housing would only lower efficiency when compared to a non-divided housing. Using a quick-spool valve with a divided housing would help spool however. It's "only" a 62mm turbo though and has the sexy new CEA wheels, so hopefully lag won't be bad at all. At least I hope not since I've go the same turbo albeit with a DBB housing waiting to go into mine.

[getslideways]

in for more updates and info!

Please tell me this prototype is for a retail kit, and that i wont die holding my breath!!!

[Max@034]

To everyone who asked....

Yes, this was one of our prototypes for our retail single turbo kit that is currently under development.

I reiterate this =

[somebody5788]

I can't imagine the kind of a monster this kit would make with 2.8 heads, RS4 manifold, and 2.8 or RS4 cams.

hehe I saw this kit in person about a month back. It looked pretty sexy

[BITRBO]

^lol. Yeah, you just have to have 4ft between the front of the firewall and the back of the motor
