AutoSpeed GT25R2 Kit is Complete!
 

We have reached a new level in terms of B5 S4 performance. We subscribe to the 3-f's mantra, <b>FIT, FINISH and FUNCTION</b>.<a href="http://www.autospeedperformance.com">Please check it out!</a>

Also for those interested in seeing the car in person, we will be attending the European Performance Labs (EPL) Meet this Saturday 1/14 10am-3pm, in Stratford CT. Hope to see you there!

Lastly and for the record, this is what we consider a street car, lol.

SON OF A BISH!!!

492 whp, and 512 lb-ft of torque on 93? Nice, Mark!

omfg

holy sheet! nice work!

WOW, CONGRATS!!!!!
 

I know it's been a long haul!

BAD ASS!

**darth vader voice** "Immpresssive"
 

thats a nice number on pump and essentially stock internals. Props props.

And it is smooooth! no herky jerky motion or turbo lag.

What's that translate to at the crank?

holy mother of gawd!!!

~500awhp on 93, very well done Mark... what about octane program switching - 93/100 ?

492/CHP = 100 - (100 * Drivetrain loss %) :-P

For those with Stage 3 set ups already...
 

It looks like the turbos and software are all that one would need to do the upgrade?

who needs k04s???????????????????????

Which bring the next question. With DPs and cat back, can I knock 2k off the kit price?

NNNIIICCCEEE!!! Me likey.

Woah! Do you get special seat belts with that? Congrats Mark, Nice work!!

630chp/653Tq

Group Buy! :D

Mark told me he's only going to sell the kit complete... maybe he can chime in here...

No manifolds and downpipes are required, this does NOT bolt up to OEM.

i think you'd need different DP's.

amazing work Mark, cant wait to get the kit on the Nogaro :)

Thanks Rob, still need to have you come down and tune your beast.

yes sir.

<begins putting worldly possessions on Ebay>
 

So is it okay to sell my wife's car for this and make her take the bus to work?

Any tests on 91? For us Cali folks

Great numbers...
 

Decent drivability. Why is the curve so shaky compared to the K04 kit? Ouch on the price, but at least it's available! This will empower S4s and allow them to go after cars like the Supra. Should also help drive resale value up as people realize JUST how much of a tuner and fairly rare car this is.

You could always just move.

21.5% drivetrain loss I guess...

&lt;begins surfing ebay&gt;

The video dyno is nice. I'm reminded of a jet... &lt;wets self&gt;

Absolutely awesome :-)

Congrats Mark!!!!!! Looks like an aweseom kit :)

THUMBS UP :) Why did it have to come after xmas? LOL :-)

Start under Other Categories -> Adult -> Videos
 

I should have my Jenna collection up shortly.

Nice!!! See you on the 14th. :-)

things look to be moving well, maybe i can up the target date to march-april :)

Mark, will you sell the Software/Manifolds/Turbos as a slightly discounted rate for Stage 3ers?
