Max@034's B5 A4 V6 Build Thread - 6 speed swap, turbo soon, etc

[Max@034]

I've modified this first page for folks just checking it out; a lot has happened since i posted this 6 months ago. The car is about to be on full standalone engine management via a 034EFI Stage IIc, along with a single turbo conversion on the stock AHA motor, running 10+ psi and going for 400whp. Theres been a lot of technical discoveries about the potential robustness of the AHA/ATQ, granted some things are addressed, so check it out:

****

A few folks suggested I started a build thread for my B5. So this is a build thread for my '99.5 B5 A4 2.8L V6 Quattro. You don't see many of these with a lot of mods on them, but I got the car for dirt cheap, I like being different, and I've fallen in love with it. Despite my 100+ mile a day commute, and my absolute constant abuse of this car, it has held through besides a marred input shaft on the 5 speed V6 transmission. However, after 8k miles of even more abuse under the hands of me, it finally got to the point where something had to be done about the noise the tranny was making. Not wanting to just throw in another long ratio V6 tranny, I decided to do a 6 speed swap to an 01E transmission from a B5 S4.

The transmission is just the first part of this cars journey; the next thing on the list is a Precision 5857 single turbo. I wanted to catalog the modifications the car undergoes, along with dyno runs, etc. Having owned a 2.8L before, I wanted to see what the potential of this engine is. Everyone is always so quick to jump into to say "go buy a 1.8T or an S4". But some of us like our little underrated 2.8's and selling/buying a car is a lot of annoyance.

The new transmission is great. I really like the shorter ratios, and it revs about 250-300rpm lower in 6th on the highway. I had an RS4 clutch in there previously, but for some reason this new S4 clutch feels a lot better. Car feels a lot faster with the shorter ratios too.

So here is a mod list, then a list of the necessary parts for the 6 speed swap, and then some pictures.

Current EDITED Mod List:
- 01E 6 speed transmission and associated drivetrain (more below)
- B&M short shifter
- 034Motorsport custom 2.8L tune
- 034Motorsport Street Density transmission mounts
- 034Motorsport poly snub mount and cage
- 034Motorsport Street Density rear diff carrier bushings
- 034Motorsport X34 Cold Air Intake
- 034Motorsport Adjustable Upper Control Arms
- 034Motorsport Adjustable Rear Swaybar endlinks
- 2.5" custom catback exhaust w/ resonator and Vibrant Stealthpower dual 3" outlet muffler
- 034Motorsport High Flow Cats
- Stasis Ohlins Mototsport Coilover suspension
- Porsche Boxter 4 piston front brakes with A8 312mm rotors
- B5 S4 rear brakes with vented 252mm rotors
- 17x8" Rota Torque rims w/ 255/40R17 Conti tires
- Full exterior S4 conversion (nearly complete)

6 Speed Swap Parts:
- 01E transmission from a B5 S4
- 01E bellhousing spacer (DON'T FORGET)
- 01E shifter linkage, stabilizer bar, and crossorod (there is an early/late version)
- 01E clutch and flywheel and pressure plate
- 01E throwout bearing release arm
- 01E transmission mount brackets (bracket from tranny mounts to tranny housing)
- 01E shifter box and shifter (you can use 5 speed, but you'll have to push down to get into 6th)
- 01E driveshaft heatshield
- B5 S4 rear diff from 6 speed
- B5 S4 driveshaft from 6 speed
- B5 S4 front axles from 6 speed
- B5 S4 or B5 A4 V6 uprights (to fit the S4 axles)

About to be Installed:
- Precision 5857 turbo with .82AR
- 034Motorsport 034EFI Stage IIc standalone engine management
- 034Motorsport Plug In Engine Harness, motorsport spec coated/sealed
- Large FMIC w/ custom piping
- B5 S4 intake manifold w/ 30v DBC throttle body
- 034Motorsport Phenolic transistion intake manifold spacers
- 034Motorsport 2.8L exhaust manifold flanges for single turbo conversion
- AEM methanol injection kit

Notes: B5 A4 rear axles fit if you swap flanges on the rear diff. Reverse light is a 5 pin Bosch female on the V6 tranny; it is a 2 pin Bosch female on the S4 transmission. Heatshields for axles can swap over; driveshaft heat shield does not. Everything else swaps right in.

[Max@034]

Also, while I know its more "feasible" to buy a 1.8T or an S4... I already own those cars. I wanted to do something different and fun with the V6, that will give me about 250whp with 8 or so psi. Kit is all planned, just need to get the S4 working before I tackle any other projects.

[Ldiaz12]

I'm glad you chose to be different, another reason to visit the forum. That intake ....will it work fine with the 2.8 12v? I really like it.

[somebody5788]

Sweet project =D, looks to me like an early 99 not a 99.5 though. How can I get a job at 034 so I can just do a project like that??? lol.

Just be sure your oil system is in top shape (I recommend sea foaming it or something) Also I'd recommend meth injection as well as a quality front mount. 250AWHP is about the limit for this engine before the pistons fry but I think with some precautions it's possible to get on a daily driver and not have any long term side effects.

Might check out scaudi.com even though you are looking into a turbo they have more information then anyone about boosted 2.8's. And there are several with built engines (usually from blowing them up at 10 psi...)

[brettj20]

its about time someone wants to do something with a v6[up][up]

[geeky]

Nic, is the the actual pressure thats causing the piston issues or the volume of air being moved? on that note, how much air does a G1 or G2 move, anyone have a graph I can look at?

[coolgraymemo]

i like that sound...

[LightSwitch]

that exhaust sounds great man, i look forward to the rest of the build.

[v3n0m]

Yeah nice project, and i think, so far that is the BEST exhaust I've heard on a b5 a4. Thats my opinion, not even close to ricy. Thats the exact exhaust i want, to sound like a v12, and not a rocket.

[Silverstreak98]

Looking forward to following this thread Max!

Also curious what modifications, if any, you had to make to the intake to get it to work for you 30V? It looks great, I'd probably buy one in a second if it wasn't a hassle to make it work.

[shokwav09]

when you said everything else swaps right in, does that include all fasteners and bolts?

[Dan[FN]6262]

are you going to make a custom manifold for the single turbo, or just pick up the OEM V6 single turbo exhaust mani that audi produces?

[somebody5788]

Nic, is the the actual pressure thats causing the piston issues or the volume of air being moved? on that note, how much air does a G1 or G2 move, anyone have a graph I can look at?

Supposedly it's the pressure. I'm not entirely sure. I would think it's the heat myself as they actually melt lol. But supposedly its because the ring seizes.

[.Mad Hatter.]

looks to me like an early 99 not a 99.5 though.

This, awesome either way though Max!

[somebody5788]

How much would an exhaust like that run for my supercharger?? lol

[Max@034]

I'm glad you chose to be different, another reason to visit the forum. That intake ....will it work fine with the 2.8 12v? I really like it.

Its the passenger head that causes a bit of a fitment problem. I just jammed the heatshield in there and it stays in place nicely, lol.

I'm quite fond of the sound myself. I'm excited to get some turbo noise in there. My S4 is hands down one of the best sounding cars I've heard, and thats not just to stroke my ego lol.


Looking forward to following this thread Max!

Also curious what modifications, if any, you had to make to the intake to get it to work for you 30V? It looks great, I'd probably buy one in a second if it wasn't a hassle to make it work.

The heatshield itself fits in there pretty good; it won't bolt up, and its a bit of a squeeze at the front end, but as you can see, it looks great. Its not a factory fit like it is in the S4, but nice. However, there is a problem; the MAF. The 2.8L MAF uses a MAF with a 4 bolt flange, so you need an adapter plate. You can see my adapter plate in the photo.


when you said everything else swaps right in, does that include all fasteners and bolts?

Pretty much. Swap the axle flanges on the rear diff, all the bolts can be reused, the driveshaft support bolts up, etc etc. You'll need the shorter hardware for the transmission brackets, and the hardware for the throwout release arm, and hardware for the linkages, etc. But the major stuff bolts right up.

[Max@034]

5857;6063726']are you going to make a custom manifold for the single turbo, or just pick up the OEM V6 single turbo exhaust mani that audi produces?

I was thinking about trying to grab one of the OEM pieces, but it is going to be so easy to fab up some flanges for the stock manifolds and run the pipes up from the collector/downpipe flanges. I'm going for a used turbo, and as many used components as possible to keep cost down since this is just the initial setup.


This, awesome either way though Max!

Oops! I am teh sux


How much would an exhaust like that run for my supercharger?? lol

Depends on the shop you use. I have high flow cats, an AWE 2.5" bullet resonator, and the Vibrant Strealthpower 2.5"**>dual 3" muffler.

I used that specific muffler because it is the same one I use on my S4 (albeit the one on my S4 is 4" instead of 2.5");

that video is of your S4??! nice, my boyfriend found this video a couple weeks ago and really wants to do this, 4" sounds really good

Yep my baby. That was on K03's. The car is now on GT28R. Should be interesting to hear what it sounds like when its done.



5857;6064637']that was my thoughts also.

I am itching to do the turbo! I almost wish my S4 was working more so I could do the A4 project, then to be able to drive the S4 finally after months of it being down. It is looking more and more simple to me. Plus, I am having turbo withdrawal.

[Coopa]

The car is now on GT28R.


This!^ Gt's in s4s are just insane.

[Max@034]

The car is now on GT28R.


This!^ Gt's in s4s are just insane.

Should be a lot of fun. Originally, it was going to be my track car, but now I've decided to keep the S4 as the daily driver, the A4 V6 as the beater, and my A4 1.8T as my racecar. I've still got 1 more A4 chassis I dunno what to do with. Shooting for about 500whp as the starting point.

Classic: owning 4 Audi's and only 1 works.

[bandit]

I really like the fact that you're trying to do somthing new but I don't see the point of having a GT'd s4 and a turbo V6 A4 as a daily driver or beater so to speak. I'd just keep the A4 clean and maintained and not have to dump cash into both cars when they break.

Your logic doesn't make sense since Max works at 034. They can't keep their hands off anything [;)]

PC-16 is a little more than 30hp bud, and its called "budget" for a reason.

[.Mad Hatter.]

It's actually not much more than 30 (over a chip)...and you can do an elim. turbo for just about the same price.

AAAAAAAAAAAAAAAAnyway.

[>_<]

Don't get upset. After exhaust and all the stuff you need for a K04 anyway, you are about 30hp more with a k04. Hell, even 50hp more, you're in pretty deep for a minimal return... :)

Sorry Max...back on topic. This build is unique, and at the VERY LEAST, some of the 2.8 guys will have a good resource for their options.

this conversation is/was hilarious.

[anmagro]

wow! this is great! i cant wait till you get this figured out with the tune and everything!

please please if there is a single request for us 2.8 guys in this build, it is to try and have the turbo run on the stock internals and see what kind of power numbers you can get from there! and if all is well, show us your dam tune! tuning has always been the biggest problem for the 2.8 weather it be in a supercharger or even turbo.

lookin good with the exhaust keep it up!

[viceprp]

It's ok Hatter I'm not upset, I know math is tough and everything.

I once thought doing a k04 would be a great mod but then I noticed the little gain that you get out of that snail. The only benefit that you get is the low end torque and the additional 30whp with a loss in mpg. The difference in your build costs is probably $300 and Mad will get an additional 80miles on his tank than you. So in ~32 fill ups, ~8 months, Madd will make up that "lose" and you will be the one throwing money away from that piss poor mileage. Also, Mad also as 30+whp then your k04 and matching torque. Making his DD, mathematically, a better choice. Maybe you should have put the time in to figure that out on your own.

Max, we look forward to the numbers that the 2.8 pushes out. Like some of the 2.8er's have said, post up some stock block friendly numbers and a tune with it. Will you guys be making a kit once all is said and done?

[Max@034]

Whoa there fellas! Don't get your panties too much in a bunch! [:D][:D][:D]

K04 on the 1.8T is perfect for most folks who just need a bit more top end and a slightly more reliable turbo setup (pushing 16psi through a K04 is more reliable then pushing 16psi through a K03). However, yes, it is barely more to start throwing on a GT Eliminator, but you are opening up the possibility of more issues simply by running more power.

The point of this build is not practicality (none of my projects ever are, except for my track car possibly), but moreso the fact that I don't know how to leave anything alone. So instead of dropping in a VR6 with a GT35R on it, I figured doing a small, easy, and low pressure turbo kit would be a great alternative.

I am obsessed with boost; especially displacement with boost. The 2.8L V6 is pretty fun already, and its been enough to give me 3 speeding tickets in the last few months [=(] and the top end power is just fine, but I feel there is a lack of low end power. I have a very long commute that involves about 3000 vertical feet of elevation gain on the way home in a short period of time.

A GT2871 running under 10psi should be plenty to give me a nice horsepower boost, but without much risks. While the AHA/ATQ isn't as robust as the 2.7T APB, it isn't a piece of crap either. I have plenty of faith that even my 175,000 mile engine will be ok. But the other reason I want to do it, is simply to find out and to help the community. I want to know what the max power output is the 2.8L can handle, and superchargers just aren't the same so I do not think its fair to compare. I firmly believe a turbo 2.8L can put down more power safely then a supercharger. However, I also have the advantage of working with a dyno, so I can get the car tuned very safely.

I will be running our 034Motorsport Wideband Controller, which besides being awesome and having barometric pressure correction, it also has EGT so I can keep an eye on everything and make sure nothing runs to hot and lean.

As I've mentioned a few times, the goal is simply 250whp, which is a bit of 300bhp at the motor. This is about the power of a Stage 1 B5 S4, and having owned and driven many Stage 1 S4's, they are at a perfect power level for daily driving. Considering I don't track this car at all, I'm going to be running a fairly small intercooler, but for safety, I will be running meth injection too.


I see this evolving into something more than 6psi & smallish turbo at some point.

You my friend could not be more correct. My original plan was to pickup an A4 and use it as the daily driver, and make my S4 the weekend/track car. However, awhile back I decided that I wanted my S4 as my daily driver, since the car is surprisingly comfortable with the Ohlins Motorsport suspension and such. What this means is that eventually, this B5 2.8L V6 will become the project car. I also made this decision since my S4 has a clean title, and my A4 has a salvage; I'd rather have the project car be salvage.


Max, we look forward to the numbers that the 2.8 pushes out. Like some of the 2.8er's have said, post up some stock block friendly numbers and a tune with it. Will you guys be making a kit once all is said and done?

Part of this project is to check out the viability of producing a kit. Making one isn't going to be that difficult, but unless we can sell 10+ a year, its probably not something we will produce on a larger scale. Doesn't mean the kit won't be available on a semi-custom basis, but we won't know anything until I finish my own and see how it runs. So if it ever is going to be available, expect it to be a year away.

[Euromike]

Making one isn't going to be that difficult, but unless we can sell 10+ a year, its probably not something we will produce on a larger scale.

Depending on what the final price ends up being, i would think you would have no issue selling 10+ a year, i bet you could sell 15-20 in an initial group buy. But thats in the future.

Cant wait to see you start the project!

[anmagro]

Update?

[Max@034]

Update?

Well right now the car is just getting major miles stacked up, and I am shifting focus to the S4 to try to get it working. I can't start the turbo project on the A4 until I have at least one of my other Audi's working! =)

The 6 speed has been great, and I've noticed a solid 2mpg better on long trips, and about 1mpg better between city and highway over the last 1k miles. As of last week, the car is sitting on new ContiSport Contact3 tires and an alignment so its driving great, besides an annoying metallic ringing I can't trace down.

I won't even be starting to do any fab work till the S4 is tuned and ready to go. However, I am planning on throwing on a set of rear B5 S4 brakes with one of our 300mm B7 rear BBK upgrades, and a Porsche Boxter 321mm front BBK.

The ringing on mine was the o2 wire mount on the transmission.

Interesting... I was under the car on Wednesday and we couldn't find anything loose. However, since this is a different transmission and the noise has continued between the two transmissions, it seems unlikely it would be something like that. I'm convinced it is something to do with my aluminum LWFW flywheel, which I did not change.

Could be. Just thought I'd throw it out there. I had over torqued the bolts on the brackets (bolts into the center dif) and snapped one. Fortunately I replaced my center dif and housing when I went with the 4:1 dif.

[Max@034]

SCORE!!!!!

The car is 100% quiet, and beautiful. Ended up being a loose O2 sensor!!! How wonderful!

I also picked up some Porsche Boxter calipers, A8 312mm rotors, stainless lines, and Apikol brackets (THANKS APIKOL!!!) since I am taking the badboy V6 to the track. Front brakes will go on with rear S4 vented brakes. This thing is coming together wonderfully.

Cool project guy, sub'd!

Before X34 intake and exhaust, but also when engine was fresher. Bout 220hhp at the crank with a bit over 20% drivetrain loss. w00t!!!

I think you should just buy my supercharger off me =P

[ZimbutheMonkey]

uhh no. Chipped hp on a 150hp 1.8t is 197ish, PC16 is 265 and almost 300 ftlbs. Apparently canadians can't do math.

So does this mean that Americans believe everything that AWE tells them? [rolleyes] No chance whatsoever that you're going to get 265 HP out of a K04-015. One of the Frankenturbos maybe, but not a K04-015.

Max, have you considered trying a rear mounted turbo setup like the Squire kits? For what you're looking for it'd probably be a hell of a lot easier than trying to cram it in the front of the engine compartment (assuming that's the plan).

To be perfectly fair, I have seen totally maxed out K04 setups reach 220whp (manifold, FMIC, full 3", etc etc). Assuming 20% drivetrain loss, thats actually 265 horsepower at the motor. Food for thought. Thats also pushing the turbo to much, and you can get the same power for cheaper with an Eliminator. And you certainly aren't doing that on a PC16 file.

There is plenty of room in the engine bay for the turbo; its actually a somewhat common thing to do with the B5 S4's, which is the area I come from (I have a slowly coming to fruition GT28R S4). The turbo sits dead center behind the motor. A lot of folks don't even know that Audi produced a single turbo V6 manifold in Europe for a diesel setup. Its too small to make proper power, but bolts right up so it makes a good model. Some people have even stuff the turbo without cutting the false firewall, however, I am relocating my battery to the rear and heavily shielding the heatercore hoses, which affords a ton of space. The false firewall does nothing really.

As I've said a few times, for now, I am just want a nice reliable 250whp. This should be easily achievable, and I am going with a really small turbo at first. I want instant spool, and primarily low and medium torque; the car already flies at the top end already with the big heads, etc. A twin scroll GT2871 or 76 is the plan. Very low boost. Meth injection to keep things cold, and a side single mount intercooler. Intake manifold has to be reversed.

[NeedingAnAudi]

Aaaahhhh, you make it sound soo easy. But most of us don't have your resources. Going to be good though, very good.

[ZimbutheMonkey]

To be perfectly fair, I have seen totally maxed out K04 setups reach 220whp (manifold, FMIC, full 3", etc etc). Assuming 20% drivetrain loss, thats actually 265 horsepower at the motor. Food for thought. Thats also pushing the turbo to much, and you can get the same power for cheaper with an Eliminator. And you certainly aren't doing that on a PC16 file.

Think you pretty much nailed it on the K04 point. Pretty much welding the wastegate shut and running race gas is not what I consider legit when quoting dyno numbers. As I like to say, it's kind of like hanging a cinderblock off your wang and telling everyone you have an 8 inch dick. But I digress...

If you're considering a GT2876r are you thinking of doing it on an asymmetrical setup then? It seems like at that kind of boost levels all you'd get above and beyond a GT2871r is lag and surge. Also, are you going to be running a T3 divided housing so as not to have to change things up once you've gone bigger?

[SleeperAvant]

Ouch on the cinderblock imagery....

Back on topic. Max – it sounds like you will have a reliable, fun V6 daily.

Yes, running a divorced/twin scroll T3 flange; the eventual future plan (with built APB 2.7 block) is a Precision 6265 or GT35R.

Also, I must have spaced out; I was talking about a 3076R, not 2876R, hahah. Looking between 2871-3076; I can get all of them with T3 divorced, however, there are no T3 divorced with an internal wastegate. I was hoping to avoid running dual external wastegates, both due to space constraints and cost. Also, due to the low PSI I am running, its highly unnecessary. One of the options would be to run a Ford 5 bolt Internal Wastegate Discharge Flange, which integrates an internal flapper wastegate to an external WG turbo.

Fact of the matter is that even a large A/R 3071 spools before 3000rpm with 2.8L of displacement and 6 cylinders. It will limit top end power a lot too, choking it. A GT35R would be an appropriately sized turbo for this motor; full boost around 4000rpm, and 700whp capability.

I'll be running a 4" anti-surge compressor housing with any of the turbos, but if I rock a 30R frame, I'll be running like 5psi.

Max, please use a quick spool valve. I'm totally intrigued by them and I feel the idea is solid and most everything I've seen about them in application shows extremely good results.

[Max@034]

This is going to be a fun weekend; Infineon Raceway (Sears Point).

I think this weekend I may have the fastest naturally aspirated 2.8L B5 A4 in the world, hahahaha... I'm swapping on my Stasis Ohlins Motorsports from the S4 and realized if I go ahead and swap over my S4 uprights and Cayenne brakes as well then I can use my track pads! H-Sport rear bar too. Supposed to be raining. I am excited to see what happens since the rain should level the playing field.

Nice, better than I expected stock, and probably better than my stage 1+ FXK03 B6 1.8t was.


Max, please use a quick spool valve. I'm totally intrigued by them and I feel the idea is solid and most everything I've seen about them in application shows extremely good results.

I second this. If I ever do a single turbo, I'm going to be going twin scroll with a quick spool valve. Though, not very practical on such a small turbo anyways, cause a single 2871 will already spool like cake on that motor.

[Max@034]

Figured I'd put a little update on my A4 DD...

I've put 16,000 miles on the A4 since I bought it, and 10k+ of those with the 01E 6 speed, and quite a bit of them with the Ohlins. The car is...well it is still running like a champ! I drive over 600 miles a week, often more, and the V6 just keeps chugging along. I've been about 4-5k between oil changes. She's a bit slower then she was a few months ago, and she's endured some pretty gnarly conditions and a few good road trips as well. Let's not forget a track day @ Infineon Raceway too.

Hasn't broke down on me once though. A lot of things are loose and rattling, the alignment can never stay still, 1st is getting a bit hard to get into but the tranny was sticky to begin with, and I never really boithered to center the shifter anyways. The Porsche Boxter brakes are continuously amazing me, and the loud exhaust always makes me think I am going faster then I actually am; and isn't that most of the fun anyways?

All in all, this car has taken my abuse and commuting better then any of them before, and the 2.8L V6 has grown quite a nice little spot in my heart. I will never talk down upon it again, especially after more then a couple folks came up to me at the track and asked what turbo I had. =)

Long live AHA/ATQ!

PS. I forgot. Over the last 16,000 miles, I've had an average of 21mpg. 21mpg. I commute a lot, but I also climb 4000 vertical feet on my drive home. I have to say, thats not too bad. 27mpg on the highway.

[Max@034]

I drove a widebody 400whp Avant all weekend. I would have never thought I'd be so happy to get back into the A4!!!!!!!!!!!!!

Sure, it's got literally less then half the power, but... the wagon was also big, heavy, and very expensive. I paid $2k for my A4, and I've only put about $1500 into it, not including tires or the suspension as I swapped that over. I imagine part of the reason I was happy to get into my A4, was because I too have Ohlins, but I also have 17's and I run 255's versus the widebody 265's, so its not that much of a difference.

Still... so glad to be back in the beater. Never thought I'd prefer a crappy '99 B5 A4 V6 over a RS4 replica B5 Avant Stage 3+... For some reason I think this may be the case even after my own GT'ed B5 S4 is done here shortly. My motivation to finish the S4, is to turbo the A4.

Can't wait to blow the AHA so I have a reason to find a APB!!!!

[NeedingAnAudi]

Was it the nogaro in a bunch of the AZ10 pics? If so I am very surprised. But I can understand that just because it's "better" doesn't make it better. If that makes sense.

In my opinion, that RS4 was the best (if not one of the best) at AZ 10th.

Yes, widebody avants certainly give me a raging hard on...

Just was surprised at how happy I was to get back into my A4. A stock S4 clutch, so smooth, so effortless, especially when compared to the Eurospec Billet clutch kit. The Avant moves like a raped ape, but man it really is big and heavy. In the end, its about the build; Christian wanted a daily driver that was comfortable, but I would have made some sacrifices to cut down on weight and comfort if I were to do it myself. My A4 is considerably more nimble, and for the first time I'm somewhat glad my S4 is a sedan and not an avant; although I wish my A4 were an Avant, mainly due to the utility.

[Max@034]

Just need one of my other B5's working and I can start the fab work.

However, I have new goals...and I think they are going to turn some heads and cause some stir;

New initial power goals? 400+whp. Stock 2.8L AHA motor. Precision 5857 turbo (essentially a 30R with a billet wheel). Turns out AHA/ATQ have oil squirters, same rods, etc. Only primary difference worth mentioning is of course, the lack of forged pistons. With good pistons, the motor should be able to hold just as much power as a stock 2.7T. With rods and pistons, it should be able to push well over 500whp.

No more pussy footing around. Compression dropping headgaskets and 10+psi!

[bandit]

I don't see this making 400whp on stock internals dude, let's be real here

I believe the 2.8 has a 2 bolt main. That kind of power cant be done with a 2 bolt main, a 4 bolt is needed from what i read. You should look around scaudi.com more. Here is a really good link. Not sure if i posted this before in this thread but heres the acutal build im talking about...

[Raacerx]

I'm not worried about anything but the pistons. Meth injection, large intercooler, low psi. Not revving it out either. I also think it's fairly safe to say that most supercharger disasters are related to an improper tune, and the non-forged pistons are less forgiving of this. Same rods, same forged crank, etc.

AHA/ATQ are missing the cross mains, which do relatively nothing for the power levels I'm interested in.
'
This will of course be an experiment; if and when the AHA goes, an APB 2.7L with rods will go in its place. However, the more and more research I do, the less differences I find. There are now folks running stock 2.8L exhaust valves with big turbos also.

[jibberjive]

Finally somebody agree's with me.

All of the blown ones I've seen looked like they failed due to being lean. Keep the intake temps down and run a better tune and your golden.

Nobody has ever blown up a 2.8 bottom end w/o oil starvation (which no engine will last through) we don't know that 2 bolts are a weak point at all. Besides you can probably drill to fit the S4 mains or get/make a girdle for the bottom end.

I would bet money that this thing fits w/o modification. Just wont have as many bolts lol.

Indeed; figure with some upgraded hardware, it will negate the main difference even more.


What steel, and pricing?

Most likely 1018 mild both to keep cost down, and to help negate some of the expansion/warping that can happen with stainless. It's not a high rust area. Stainless will certainly be available, but figure quite an increased cost and it is unnecessary. Exact material and final pricing won't be ready for a bit.

The only thing I will note, is that the VAG ETKA (along with dealer, etc) only shows 8 main bolts for AHA/ATQ, versus the 16 that are listed for APB. Are you positive thats not a 2.7 APB block, bored out to 2.8L?

Possibly they drilled and tapped?

See his pictures are confusing; you see he rebuilt the motor with it still in the car... However, then he has pictures of the motor out of the car. The picture of the motor out of the car show cross-mains, and I am 95% sure that the AHA/ATQ do not have cross-mains. I believe that he must have switched to an APB block or something, unless there truly aren't any differences. Someone must have a picture of a AHA/ATQ bottom end.

You can clearly see the 2 bolt mains in this picture of his motor, to the side. Possibly, the block is actually tapped and ready to go, but the V6 uses different bearing caps? I am very intrigued.

Main Questions:
- Does AHA/ATQ have 4 bolt mains? If not, can they be used? If so, are the provisions there?
- Does the AHA/ATQ have cross-mains? Maybe just provisions? Block is absolutely identical in every other aspect.

He started rebuilding in the car and then decided to have the block gone through at a machine shop. This all I know

[somebody5788]

I had the 4 bolt mains drilled, the stock 2.8 comes with holes for 4 bolts in the caps but not in the block.

Oil squirters in the block are standard, oil squirters in the heads are apparently only on some ATQ heads. AHA do not have oil squirters in the heads.

Fantastic. Great to confirm. The part number differences are just freeze plug orientations and the drilling of the main bolts. The fact that it even comes with the 4 bolt bearing caps is fantastic, because then they won't need to be machined.

The only thing that made me curious, was the oil squirters in the heads... I have a set of AHA 2.8L heads sitting here, and ATQ 2.8L heads sitting here, and there is not one single physical difference I can find and I've not heard of oil squirters in the head?

It sounded weird to me lol. Couldn't tell ya why it would have them on the head and I wouldn't worry about it anyways. And I know what you mean, having the caps with 4 holes means much less work! In fact "technically" you could drill the 4 bolt mains while the engine is in the car! I'm thinking low compression head gasket and 4 bolt mains and this engine could hold anything an S4 motor could as long as you are much more careful with EGT's and AFR's.

You should do a reversed RS4 intake manifold though. You can install it backwards so that the throttle body is still on the back of the engine.

I'd also do the Phenolic spacers.

Makes more sense to flip the throttle body to the front, due to the intercooler. Otherwise, you need about 40% more tubing in order to run all the way to the front of the car, and all the way back to the turbo/throttle body. Unfortunately this is where the problems begin, primarily because;

A) The stock plastic intake manifold is not going to like the increased temps of a turbo
B) The V6 throttle body has a different bolt pattern then the S4 intake manifold
C) The S4 throttle body is drive-by-wire, and Pre-2000 cars (like mine) are drive-by-cable
D) S4 intake manifold requires S4 fuel rails, etc

The goal is to do this with the least amount of fabrication and parts as possible, so I haven't figured out the best course of action there.

The RS4 intake manifold also requires 034EFI billet fuel rails (or RS4) and needs to be custom drilled to fit any throttle body but an RS4, which is about $700... Also, there isn't going to be a big performance increase at the levels of power I will be going for. The manifold doesn't start to shine until the boost really gets up there.

[somebody5788]

Trust me the intake temps are the least of your worries if you are going to be intercooled. I had nearly 200* intake temps until I intercooled mine.

[Dan[FN]6262]

not having forged pistons is not a big deal, as long as the AFR is kept in check.

[somebody5788]

This is what I was thinking, EGT's and AFR's and I think this engines strong as hell.

[Dan[FN]6262]

This is what I was thinking, EGT's and AFR's and I think this engines strong as hell.

Since EGTs are directly affected by AFR, that's kind of a given. What kills a piston is running lean, lean is HOT and HOT melts pistons. Detonation will blow apart a rod before it will a piston, wristpin, or crank. That is, unless you have kryptonite rods and glass pins. There are always variables, but a general rule of thumb.

5857;6621221']Since EGTs are directly affected by AFR, that's kind of a given. What kills a piston is running lean, lean is HOT and HOT melts pistons. Detonation will blow apart a rod before it will a piston, wristpin, or crank. That is, unless you have kryptonite rods and glass pins. There are always variables, but a general rule of thumb.

EGT's are also controlled by timing and type of fuel.

So just as some cliff notes if I read correctly:

2.8 bottom ends have forged rods and cranks
2.8 bottom ends have bearing caps drilled for 4 bolts but the block is not.
ATQ heads have oil squirters

I've got an ATQ head right here, and an AHA head right here, and there are absolutely no differences or additional oil squirters. Plus, I haven't the faintest idea where the oil squirters in a head would go?

Wow interesting. Most definitely does not have that.

So the composite intake manifolds are holding up to supercharger temps?

I haven't heard of the intake causing a problem.

034 should probably make a centrifugal supercharger kit for the 2.8 ;) I know we could both test it out for a year and then it could go up for sale hahaha. Just mount it exactly how my supercharger was.

I would donate my extra set of supercharger mounts to this cause

[Dan[FN]6262]

EGT's are also controlled by timing and type of fuel.

like I said, there are always variables. wastegate and manifold design also affect EGTs. variables.

[somebody5788]

Ugh, this really sucks. I have an the expensive ass 034 IIc with the 4 bar MAP sensor, a full supercharger kit, Walbro 255 fuel pump, Adjustable FPR, and more yet I don't have anyone to tune the dang stand alone......... I could have a nice amount of power =(

Funny thing, not all APB engines use oil squirters in the head lol. So one more area where they don't differentiate.

[anmagro]

Wow, good info here, im glad that we got everything figured out about the 2.8 bottom end. To the OP, I understand the idea behind not going the 'crazy, buy everything and out-do everything' way. This is good and more realistic for most 2.8'ers and such.

I just need to find a way to give 2.8'ers a cheap option that produces the same power as a stage 3 1.8t or stage 2 S4 hehehe.

Hey i hear ya, i think your on scaudi right? I had my hands on a centrifugal charger and it slipped away. As far as i know there easier to tune than roots blower and would be great. Maby not Stage III 1.8T but close. Low heat too.

Yep! If I felt a bit more confident in the AHA motor, I'd do a 6262 so that when I was ready for rods or a built motor, I could push 600whp. However, the 5857 should spool like K04's on an S4 and be able to put down similar power, and I won't need to worry so much about pushing the motor too far.

PS. pretty excited to see if I can extract anymore power from the 2.8 naturally aspirated by self-tuning it.

Most definitely! We make almost all our files available on our website!

I'm going to look into how difficult it is to run a B5 S4 manifold with my current drive by cable V6 throttle body; the runner length and lack of plenum is just too much.

We have Phenolic Transition spacers which smoothly go from 2.8L Big Port to 2.7T Small Port, so you can run a 2.7T manifold on the 2.8L head without weird turbulence.

Yep, we have SAI block off plates. Just came off the CNC. I am doing the same. Not sure they are on the website yet.

PS. At quick glance, the 30V DBC throttle body seems to look nearly identical in bolt pattern to the S4 DBW throttle body; this would save a lot of time and money.

If the rods are the same as the S4, they're cast.



Funny thing, not all APB engines use oil squirters in the head lol. So one more area where they don't differentiate.
Yeah, none of my S4 heads have had squirters, and neither did my ATQ or AHA set. I saw them in the Bentley though and was wondering where they were ha.

The S4's are all DBW but he's not. Also the 034 IIc isn't compatible with DBW so you have to convert. Therefore if you wanted to try to use an S4 intake manifold you would need a throttle body that is DBC but fits the manifold. If the 30v one fits from the AHA engine then this is a simple solution.

[Max@034]

Forged crank on both, same cast rods, forged pistons on APB and non-forged on AHA/ATQ. That is what I meant Mike.

The 30v DBC throttle body looks to have the same bolt pattern, and is similar sized to the early S4 throttle body. 65mm or so. Generally with 034EFI S4 conversions, we sell a custom DBC 75mm throttle body that bolts to the stock or RS4 intake manifold. However, that is too large for my application, and our smaller custom TB's don't fit the bolt pattern unless I use an adapter plate, but then it sticks forward a bit too much for a single turbo 90 degree TB inlet. I don't want to clearance my locking plate.

It seems the squirters are for late ATQ and late 2.7T C5 chassis cars, like BEL. That being said, not one single person I've talked to has ever seen that. I can't even find it in ETKA, but maybe I should be looking in the Europe market? Thing is, did Europe even have AHA/ATQ? I thought they had the 2.4 and a different 2.8, hence the less aggressive cams found in the Europe 2.8L.

[Max@034]

Oh, and a couple pictures from yesterday. Vented B5 S4 brakes in the rear to better match the Boxter calipers up front.

IDK I see aboloutly no advantage to DBW. The RX-8 I used to have had it, so much less throttle control.... It also had electric power steering like a lot of new cars do. I tried to have some fun and throw it around a corner only for the steering wheel to lock up in the middle of it..... If it had normal DBC and hydraulic steering that thing would have been sooo much better.

[Max@034]

Began the S4 facelift exterior conversion this weekend before I slipped a disc in my back and killed any future progress for the next month... Weak.

Swapped over the S4 rear bumper and S4 hood, already have the S4 headlights installed. Removed the S4 fenders and side skirts from the donor car, just need to swap them. Last thing is to swap the doors, but I need to swap the door cards since my car has Bose and the donor S4 does not.

Only thing I am missing is an S4 front bumper; once that is acquired, I will pull and roll the fenders aggressively front and rear, and then get the rear quarter panels and trunk painted to match the facelift silver color (since hood, front fenders, side skirts, doors, and rear bumper are the lighter silver). Roof is getting brilliant black. Hoping to get all the painting done pretty cheap.

I also picked up a 3" exhaust, so all I will need to fab for the turbo exhaust is a downpipe. 3" may be a tad restrictive for my goals, but I'm on a budget.

5857;6633553']Because its OLD technology. AEM is cheaper and can use DBW.

We intentionally keep our system somewhat simple so that it is incredibly user friendly; that doesn't mean there are limitations. Some of the fastest Audi's in the world are running our systems. We have 3D mapping, anti-lag, push-to-pass, MAP change on the fly, CAN integration, etc etc. I'm not really sure what else you would want. DBW is harder to tune and doesn't offer any benefit to a standalone system. It's primarily emissions based, and DBC is much simpler. We use DBW on our GTi-RS project car only because the motor is in the back seat and running a cable would be tricky.

We also have tons and tons of basemaps for all kinds of Audi and VW setups, ranging from 16v naturally aspirated motors, to fully built twin turbo 3.0L V6 motors, to 1000bhp 5 cylinder 20v motors...

Finally, AEM won't offer you any type of support for your specific vehicle; its a universal system. There is no "Plug and Play" engine harness option, which we offer for any Audi or VW (or almost any other car) that you require. Not as if the AEM system is bad by any means, we just have designed our system specifically with these aforementioned aspects in mind.

Just don't get why folks sometimes claim our system is "old technology" when it offers everything you need and more, without being overly complicated. Happy to hear your response.

No no, I was not taking offense by any means! As I said, I'd love to hear your response to what I said, merely in a debate type of way and not so I can try to rip apart your responses hahaha. I love discussion, and while this is my build thread, in the end its really all in the name of technical discussion so please don't worry about cluttering anything. Plus, since my car will be running standalone, it is definitely pertinent to the conversation.

However, feel free to PM me if you prefer as well. I enjoy criticism and I will certainly address things, but don't ever take it as me attacking anything either. I also like to hear why folks may not prefer our system, so that I can understand why and potentially address that in the future.

[Max@034]

I say get rid of the "A4" and keep the "2.8 Quattro" as per the great nature of the build.

I think I want it to say A4 and 2.8L; it will make people think the car is slow as hell. I love sleepers. But I'd be down to do the facelift A4 badge.

***

I also think I'm changing direction a little bit. Despite really wanting to push my 200,000 mile AHA engine in stock form, since I need to remove the motor to do compression dropping headgaskets and fully fab everything up nicely, I figure I might as well do a little work to the motor as well so I can push boost a bit more. Also since I'm tuning this thing myself, it would be nice to have a big more leeway.

Unfortunately, this always brings up the inevitable "well, while I'm in there, why not..." which is what caused my S4 K04 build to turn into a built 2.8L twin GT28R. I don't want that to happen, however, I also feel it would be stupid not to at least throw in a stud kit. But...if I remove the upper oil pan and install a stud kit, then I might as well tap the block for the 4 bolt main caps the motor already has. But...if I do that, then why not just throw in some new 034Motorsport Coated Main Bearings while I'm in there? But...if I'm really gonna go through the trouble to do that, why not do some 82.5mm JE pistons and IE rods.

But then I'd be able to run 700whp on the block, and the stock heads would be holding me back. And that is one thing I'm not interested in doing; heads cost far too much and there is no reason to spend the $$$ on labor if you don't at least replace exhaust valves and springs/retainers.

Sigh.

I think the most likely route will be to install a Main Stud Kit with the 2 bolt configuration, and keep the stock 82.5mm non-forged pistons along with a big ass intercooler, water meth, and a our 034Motorsport Wideband O2 Controller Stage II, which has an EGT.

[NeedingAnAudi]

Oh man. You have it rough [:p]

[somebody5788]

This is what I would do:

4 bolt mains, new OEM bearings, and I would consider doing rings and just having the block honed for the hash marks. End result would still be a 2.8 but a nice fresh healthy one.

[jibberjive]

There's no point in spending that much on new rings, honing and misc engine hardware just to throw the stock non-forged pistons back in. A new set of OEM rings is like 1/3 the cost of a complete new piston set, which would come with rings as well. I'd just do the main bolts (if even that) and not remove any of the rotating assembly.

If you go with new pistons your gonna want to make sure you have perfectly matched cylinder bores which is even more machine work and more money.

I'm with you on this one Mike; if the motor goes to a machine shop, then its getting fully rebuilt... The machining costs and time to fully disassemble is simply not worth it without replacing rods, bearings, pistons, etc. I've got good compression still. And as I said, if I do pistons then theres no reason to bolt everything up on stock heads... Labor on the heads is what kills it; not the valvetrain cost itself. But I don't want a shortblock that can support massive horsepower, but with heads that can't even rev past 7k.

But... everyone keeps thinking that AHA/ATQ exhaust valves are different from APB 2.7T, or 1.8T, or 16v, or 20v 5 cylinders, etc etc etc. They are the same. The forums have seen some people pushing over 500whp with stock 2.7T valves, which is probably not something I will be doing with a 5857...

If only the AHA had the same stroke as the 2.7T, and I could just throw in my old S4 pistons!!!!!!!!! Which, once again, brings me 360 degrees back to my original plan of swapping in a stock APB 2.7T motor... We know they can handle 450whp easy, and I can toss in some rods and bearings, avoid honing, and push 600whp. DAMN ALL THESE CHOICES!

On another note, fabrication will begin next month for the rest of the exhaust manifolds.

[somebody5788]

Just drill the 4 bolt mains with the motor in the car hehe. It would take a long time but it's doable.

[Max@034]

Just drill the 4 bolt mains with the motor in the car hehe. It would take a long time but it's doable.

Motor has to come out for, at the minimum, compression dropping headgaskets and easing the turbo manifold piece/downpipe.

[Max@034]

The S4 is working, drove it 70 miles to work today; this means it is time to order up the Precision turbo and get this A4 V6T party started.

I've narrowed my choices to the following:

1) The Cheap Route: pull motor, compression dropping head gaskets, and ARP 2 bolt main stud kit (coated main bearings depending on how the OEM bearings look).
2) The Smarter Route: pull motor, JE 9:1 82.5mm pistons, Integrated Engineering h-beam rods, 034Motorsport coated main bearings, rod bearings, thrust washers, drill/tapped for 4 bolt mains and ARP stud kit, but keep the heads stock.

If I go #2, then I will rock the stock 2.8L heads for awhile until I can get them fully built (intake, exhaust, springs/retainers), and then either swap them onto my S4 or the A4. My S4 2.8L heads are semi-built, but I can't decide which car will be pushing more boost or power so I don't know which one I should invest in.

That being said, I think the #1 option is the best and should be able to hold 400whp without much issues.

Going large Garrett intercooler core, got the S4 intake manifold, confirmed I can use the AHA drive-by-cable throttle body on the S4 intake manifold, and basically I'll be running the charge power next to the air intake, down to the intercooler, and then up the driveside where the driveside bi-pipe would normally be on a 2.7T.

Also, here are some pics from a customers car, to give folks an idea. I hope he doesn't mind I am posting them.

I just want to see a 2.8 make 400hp w/o any major work done to it. I didn't really consider drilled mains very major though.

Hey Max, whats the ID on those 2.8 exhaust flanges? I'm currently in the parts collecting process of my own single turbo build and since you guys have released these I am contemplating using them with the 2.8 manis I have laying around as an initial set up as I am tired of the car sitting around in the garage. Plus my initial set up will be on just a stock block and make "only" mid 400s at the wheels.

[ApeX-CrZn]

no point in building the engine up you've pretty much done that with the s4. I would think this builds purpose would be to see what kind of power you can get out of a relatively stock 2.8 for cheap, no?

I agree. This build's direction has changed vastly from page one. I'd like to see a stockish 2.8 block make some power.

My cars always start off with mild intentions; my B5 S4 was simply going K04 Stage 3. Then 2.8L big port heads and K04s. Then bigger turbos. Then built motor. Then carbon clutch. etc etc etc.

We will see. It is most likely I will just do a 2 bolt stud kit and the compression dropping head gaskets and shoot for 400.

Yes but I'm getting sick of pulling motors and more into the mentality of do it once. We will see though. I don't really to spend the money to build another motor anyways, so it wouldn't be an ideal thing. But... In the long run its not much more for a lot more peace of mind. If the car was ME7 and DBW, I would maintain the stock Motronic and keep it mild. But since I am self-tuning, I wouldn't mind being able to push it past 500whp hahaha.

[Max@034]

Finally decided what to do;

Precision 5857 v-band turbo with larger .83A/R exhaust side
Stock AHA 2.8L motor
034Motorsport 2.8L Exhaust Manifold discharge flanges
034Motorsport/ARP main stud kit (2 bolt)
034Motorsport Compression Dropping Head Gaskets (should bring it down to around 9.3:1 stock S4 compression)
Eurospec Reusable Head Bolt Kit
eBay FMIC kit
AEM meth injection
034EFI Stage IIc standalone engine management - full DR-25 coating/insulation, custom harness
034EFI Stage I wideband controller

So everyone who wanted to see what a stock motor can do, should be happy.

[somebody5788]

I'm sure it'll be very impressive.

Stock AHA 2.8L motor
while i would consider it grossly unfair for you to shoulder all the burden of taking the 2.8 in this (much anticipated, for me) direction, i'm glad you're leaving it stock when the turbo system, EMS and tuning come into the mix. i just read this thread all the way through and in the few posts above this when you were considering doing a build before the turbo, i admit i started getting a bit disappointed. glad it's staying stock - even at 200K.

i've always been vocal (to my Audi friends) that i preferred the 2.8 A4s to the 1.8Ts and i was always the lonely voice. i'm glad to see some of the enthusiasm i've seen for your project.

[RickyCastro]

any updates?

[Max@034]

any updates?

Oh man...

Unfortunately, this project may end abruptly; I may be shifting my focus to another A4, and taking this V6 back to stock. [=(]

While the V6-T would be fun, it is a ton of work and I have another A4 that would be much wiser to invest my time and money into. It already has a new paintjob and S4 body kit, interior, suspension, brakes, and a GT28RS 1.8T.

Hoping that someone else will step in and take up where I left off. Still a chance I'll stay with the V6, but I have no reason to have 3 running turbo'ed B5's.

[flynnr]

figured this would happen... you have so many resources at hand? why would you want a laggy 300whp when you could have something unique?

[Max@034]

The real reason?

I'm suddenly single turbo'ing my S4. I don't need two single turbo B5 V6's.

The good thing is that all the parts will STILL work for the AHA/ATQ V6... But this way, i can push 35psi. =)

Stupid bump, but are those Leistritz high flow cats.....as in OEM cats? In your first post, you can see a pic of new looking cats, and in your mod list you mention 034 high flow cats.

[confused]

[Max@034]

So yes, this project is officially dead. I am just about at the stage of beginning mockup and fabrication of the single turbo, for my S4.

Unfortunetly, I will be ditching this car all together. Just need to pull the 6 speed S4 drivetrain out, install it into the 1.8T, and then sell.

The 1.8T has a nice new Casa White paintjob, full S4 body kit, etc. I am going to rebuild the cylinder head and drive it till I want to go bigger or need to do more work.

However, folks shouldn't be bummed, because this doesn't really change anything in regards to production of the kit. I will still pay extra attention to ensure fitment on the A4 V6, and as we've discovered throughout this thread, there are surprisingly little difference between the AHA/ATQ and the APB. I'll be looking for an A4 V6 eventually to help test the kit out with lower boost and a smaller turbo.

My Precision 6262 turbo will be here next week for the S4.

Just the heat shields so they look OEM! They are high flow units though, just camouflaged. =)

How were the 255/40's? Did you rub?

[Max@034]

How were the 255/40's? Did you rub?

Only thing I run on my narrow body B5's.

A quick fender roll and ET35 offset with an 8" rim, and they are perfect. No rubbing. 255/40R17

255/35/18 fits as well, but requires a +5mm pull up front.

It is official; the project has begun.

I'll periodically probably come in here and post updates pertinent to A4 owners.

SUPER good call on the switch to the S4.. a shame that it's already twin GT'd. guess you're going to find a nice home for that kit? which one was it btw?

ATP 2560 Eliminators.

I am going to pull them, most likely rebuild to be safe, and then resell them with WG all redone/reset.

I believe they can do close to 500 with meth and 30psi, but I've only done low 400's @ 20psi as I've ironed out other issues.
