Extremely excited to finally get this project going; its been a long time coming.
Many OG Audizine folks will be familiar with this car; it won the 2004 Eurotuner 1.8T Challenge and was owned by an old forum member, audimus ed. It's probably one of the most well used B5 A4's out there, with over 215,000 miles, tons of track time, and even driven briefly by Gary Sheehan at one point. It was purchased by a buddy about a year ago, and we were going to build the car together, but plans changed and we decided recently that I would take on the project by myself. She finally came home yesterday.
The car sits basically the way it was back in 2004, with a few minor changes, specifically the gorgeous Casa white paint job and 4 bent valves in the head (2nd or 3rd time this has happened...). She's already pretty dialed and been this way for quite awhile, with an APR Stage 3 complete turbo kit, spherical control arms, Neuspeed bars, Stoptech brakes, Recaro seats, 4:1 diff, and more.
However, I've got a bitttttt more then that planned for her!!!
First order of business is to get the car up and running, which means a complete Supertech valvetrain into the AEB head. Inconel exhaust valves, stainless intake valves, high rate valve springs, and ti retainers are all going in next week. Hopefully add an Integrated Engineering drop-in "factory timed" mild intake camshaft, and we are good up top! Going to keep the shortblock stock for now, since I do not want to build the 058 block; I will begin building an 06A block on the side.
The car will be run on 034EFI standalone engine management system instead of the APR Motronic; specifically a Stage IIc, which gives me incredibly easy tuneability, as well as a host of options needed for racing, such as "Push to Pass" boost control (kills understeer by a huge amount), gear based boost control, anti-lag, flat foot shifting, CAN integration for logging, AIM dash, and much much more.
After the engine is up and running, I will be swapping the 01E 6 speed drivetrain over from my other A4, at which point I will do the rear cage and the interior starts to get pulled in preparation for the front cage, along with battery relocated to the trunk and a complete set of 034Motorsport aluminum subframe bushings and motorsport/track mounts to replace the aging units.
Then comes the most important part of the car, suspension; while it is already outfitted with adjustable control arms front and rear, it is only sitting on a Koni strut/spring combo which is hurting its performance. The car will get either another pair of Ohlins Motorsports, the Ohlins off my S4, or a Performance Shock Inc. rebuilt and revalved set of Koni coilovers with 800/900 Hyperco springs (basically more aggressive Tracksports). I will also be swapping out most of the CPP adjustable control arms and links for our own updated 034Motorsport spherical race control arms, top and bottom, front and rear.
I currently run 235/40/17 Nitto NT01 DOT-legal tires on some Kosei T1's, but I will be rolling the fenders even more and pulling a bit so that I can fit 245/40/17 NT01 or RA1s (much larger then street tires); I will run the standard 255/40/17 for street tires that I run on all my other B5's. Besides pulling the sunroof, I don't have any body modification plans, since the car has a full S4 body kit and a new paint job. Pains me to know that this will probably get damaged as a track car, but so be it.
The 06A block will have JE 9:1 pistons, 2L crank, IE rods, and may immediately go to a dry sump system. The goal is for a competitive and relatively easy to maintain Time Attack car; there is a pretty vibrant TA scene here in California, and another coworker is doing basically an identical build as me, but 2.0L from the start. We are very lucky to have the 034Motorsport B5 A4 Time Attack race car right here, since it is one of the fastest road-racing B5's in the entire world, and we are both using it as a model and inspiration.
Next year I have the goal of removing all glass as well as some other major weight savings. I want the car under 2750 without full stripping, which shouldn't be a problem considering the 034 Time Attack car sits about there and still has full glass and a very heavy cage. With a bit more planning from the start, I should be able to do a lighter and just as effective design.
I'll be updating this as time goes on and I juggle time with my other project; my single turbo B5 S4.
The nice pics are all stolen from Ed; I've been to busy to take my own. But the car looks just as good now as it did in the photos. If only I could easily insure it for more, I'd swap my S4 into this chassis and make the race car out of my beatup S4.
2001 A4 1.8TQM. Custom turbo back (eBay test pipe, LaBree downpipe, 2.5 inch piping back to a MagnaFlow muffler). Stage 1 tune. K&N Cone filter. RS6 Wheels painted dark gray with Continental DWS tires. ST Coilovers. Coming soon...2.0 coil packs.
For sale...Brand new, never used, still in box Bosch rear o2 sensor.
Very interested in what you do as far as weight reduction. My car needs to go on a serious diet :)
It's a give and take with the cage; I want to go as far as I can without dipping and trussing the frame from the very start. I'll probably keep the stock glass this year, but moving to composite can save well over 100 pounds. Besides moving the actual glass, just getting rid of the motor/regulator assembly is significant. The sunroof weighs over 50 pounds and sits at the highest point above the COG of the car. I'll do a carbon roof eventually as well; they are surprisingly less money then I thought, but aren't possibly without the cage fully done since the roof is a load bearing item.
Aluminum uprights, no glass side windows (i'll keep the windshields for awhile), no sunroof, interior gutted, remove A/C, 1 piece driveshaft, my Koseis weigh 15 pounds each, Odyssey race battery in trunk (the weight difference is almost negated by the amount of wire necessary, but it does move weight rearward). The steering column is a big one.
Unfortunately, the other half of the battle is making sure not too much weight is removed from the rear compared to the front; of course, its always easier to ballast to wherever you want.

They are true Work, but unfortunately did not come with the car. =( Car originally came with BBS rims but I traded em for some stockers and a rear roll cage.

Thanks much, Rob!
All concerns that I have when I put a plan of action for my potential setup... However I have thoughts of going a little bit more radical with the car and making something like an exoskeleton open cockpit racer..

A big huge thanks to Supertech! This just arrived today;
We are big Supertech dealer, its what I run on my built S4 motor, and what we love and recommend @ 034Motorsport. Folks can always hit me up for a valvetrain package!
whats the details on the original recaros? also, why are you choosing to build a 06A instead of the 058, did I miss the boat on something?
The Recaro are Sportster, and I'll probably be selling them soon since I want to find a matching seat for the Status seat.
As far as the 06A vs 058, there are a variety of advantages of the later 06A block. No balance shaft is the main one, no external water pump, etc etc. The balance shaft has to be clearanced for the 2L crank, requires the ABA crank, etc etc. Besides some different coolant and breather hoses, which we make, everything else fits on it.

Yes, originally black when it did the Eurotuner challenge. It got hit in the rear or something and then got the new paint job.

I did. It's a custom Status seat, Tjin Edition; FIA drift. One of a kind. Came out of an R34 Drift Skyline that has a GT42R, pretty famous car, all over the web and the magazines.
I am shifting funds from different areas of the car; namely, I am selling off my Stoptech brake kit and my Recaro seats in order to help fund the rest of the car (PM me if you are interested!)
I already have a Boxster BBK kit with race pads that is sufficient for my current needs, and I already have the above Status seats.
Roll cage goes in very soon as well, and the head should be back from the machine shop in a couple weeks.
Still debating whether I want to deal with the trouble of swapping over the entire 01E drivetrain from my other A4; the car currently has an RS4 clutch in good condition and the transmission is shifting fine, but I know once I am 2.0L and putting down 400whp...that things might not be as happy.
I don't care about gear ratios for drag racing; this is a road racing car. I've never owned a powerful enough 1.8T to bust 3rd gear. I will most likely install my SPEC 3+ disc and RS4 PP into the A4 when I reinstall my carbon clutch in my S4. It is holding my 450-500 ft/lbs of torque I've been running around with, so that should be plenty for the A4.
However, the fullsize clutch kits shift so, so, so, so slow.
Are you planning on running a 30r size turbo? You keeping the Apr hardware or moving on?
Yes, am going to be running a Precision 5857 turbo; the motor build is basically going to follow our Time Attack A4 build, just maybe without the dry sump to start with.
SPA manifold and downpipe.
The APR Stage 3 kit will be for sale as a whole package, including the inconel manifold. I'd love to keep the manifold but I don't want to be limited by the T-25 flange. For the time being, I'll just be running low boost and keeping the revs low as well, while I build up an 06A block.
Integrated Engineering is helping out, so a big thanks to them! If only they weren't out of their CVA1/A2 cams though!!!!!!

I could use a good shifting 01A if that helps at all. My 2nd gear syncro is fubar'd under load. I have been eyeing those seats too. Lets talk next time i am up there.

Hmm, a car after my own heart. Keep up the good work.
Nice to see some B5 A4 track cars popping up.
I'll be at big willow this weekend. Just got my car back from the alignment shop; -2.1° in the rear, thanks to the 034 rear adjustable CA's.
Maybe I'll see you out at some of the Socal or Audi Club Track events.
DO WORK!

Definitely need to get out to Willow Springs; haven't been to any of the SoCal tracks, but we do have 3 great ones so close to home up here. The car will be street legal for awhile I hope. I've currently got full CPP sphericals, but need to change over to 034 stuff!
Yo, I was watching a B5 track car on you tube. If I am correct they had a 2.o vr6 in there pushing 450 HP. Wicked ass car, I think it was quattro also. Kinda made rethink VR6 in a B5. I'll post the link.

Yes the 034Motorsport B5 A4 Time Attack race car originally had a 24v VR6 turbo motor, but we swapped it out for a 2.0L 06A turbo motor since it saved weight, had better weight distribution (didn't overhang so far forward), and dropped about 1.5 seconds on the track.
My car that I am building here will be following in the same basic footsteps, just slowly iterating towards it.
Very excited to say that a lot of parts have been sold, and progress is moving forward to build up an 06A right now instead of in the future.
RS4 front fenders have been added to the mod list; going to rock the ghetto RS4 front fender and stock sideskirt rear, since the rear can be made to fit a 265 tire pretty easily. I'd like to fit a 255 r-compound for now, or 265 street. Hopefully pick up the rear quarter panels and doors in the summer time, then run a true 275 r-compound.
Excited to get the 06A in with the 01E and then get this baby running!
Max I would look out for those supertech valves. I've seen them ruin a handful of motors
We've had great success with em, they are local to us, we work directly with them, and they helped me out big time on this project.
I run them on my S4, we run them on our GTi-RS and our Time Attack B5 A4. Ran em on our VR6-T that produced 800+ whp and do pretty much every build of ours with them (and that is a LOT of builds). I don't really know of any of our builds that have gone wrong because of the valvetrain.

No worries, I've just seen when they are supposed to bend they snap causing all kinds of problems. Happened to 3 separate builds by 3 separate people around here

Pretty sure Mike Hood runs them in his 500+whp B5. No problems there either..

What are you going to do in the rear to get 265's to fit. I ran a street tire 255/35/18 et+32 with very light rubbing. The sheet metal in the rear looks double walled. Currently running 235/40/18 r-comps. I want to go to 255/35/18 r-comps. With the increased camber it looks plausible.
Why are you going with an 01E?

Why are you going with an 01E?
255 street tires fit just fine with appropriate track camber and no trimming, just careful placement between the upright and the fender. I tend to run not as wide rims so I can get a better contact patch, which helps fitment (ie, a 255 wide tire on 8" wide rim, versus a 255 tires on a 9" wide rim).
The fact that I also ONLY run 17" wheels makes it easier as well, due to the larger sidewall aspect ratio/height. However, with a 5mm pull and roll and some care taken to flatten it out, 265/35/18 street tires will fit. 17" version will fit even better with a not as wide rim. Finally, this is a race car so I'm not concerned with the aesthetics of it. Although, it will hurt to mess it up since it has a brand new paintjob and perfect body panels. But with the salvage title and all, I need to just look past the perfect exterior and interior.
And I am going with the 01E because of the strength, because I have it, because it needs a rebuild anyways, and because the 01E in our Time Attack car is bloody gorgeous. Cryo and WPC, lots of care taken when built, Allroad 3rd and 4th gear, custom 5th and 6th. 01A just cannot handle more then 400whp in my opinion; at least not continuous beatings and so much time spent in 3rd/4th gear. However, for road racing, I'd say the 01A has better gears stock.
I have a complete 01E drivetrain on my other A4, and I need a 5 speed drivetrain to sell it, which is the other reason I need to put the 01E in this car. I know at some point in the future I would be swapping to an 01E anyways for strength and such. I'll take the sacrifice of slower shifting with the heavier gears.
Also, if it wasn't clear before, I run 255/40/17 on all my B5's. 8" rim with 35 offset. Only the front needed a little rolling. Same contact patch as a B7 RS4 stock.

Exactly. I am also running a Gates racing belt, so unless one of the other components fail (and I religiously replace timing rollers and tensioners), I shouldn't have an issue. If something does go wrong, I'm expecting pretty catastrophic stuff to happen anyways.
