5-Cylinder Teardown: Audi Ur-Quattro Engine Build & Swap Underway!

[@adaml.8300]

I am so stoked for this episode! I love this car… and it was one of the last project’s of Ken and Lia’s that I got to watch.

[@stanceworks]

I recorded a bit at the end for Ken but clipped it out. It’s better suited for later.

[@SadDusti128]

I loved that video of Ken working with Lia. So sad to hear of his passing.

[@SadDusti128]

@@stanceworks Thanks for clipping it out. That was a good decision and very respectful. You are a good guy.

[@TURBOTRISTO]

keep ken out of it, this has nothing to do with his tragic passing, no need to virtue signal to people

[@alfonzo312]

Just things I can think of right now to look for: AAN engine things to keep notice of: -Cracks in timing gear key or fully sheared, closely inspect. Full billet options available. Issue also in small chassis cars -Cracks in cylinder head from spark plug holes. Not a total disaster, there is a spec for them in the AAN manual -Lots of small chassis cars like the URQ get the 3b engine from a '91 200 due to more compact intake design due to radiator clearance issues in small chassis that large chassis cars don't have issues with. Not 100% sure intake manifolds are a direct swap. -Many off the shelf options for retrofit newer ignition coils and harnesses. Popular and accessible options seem to the 2.0l red tops from newer VAG. -There is reported issues with ARP main studs and fouling oil check valves in the block of AAN. Just something to look into and research. Urquattro things: -Closely inspect the firewall around the clutch master while actuating, small chassis cars don't have enough bracing in the firewall for these early hydraulic set ups and they often crack/flex causing issues with clutch master alignment and rod breakage. Some aftermarket solutions tie the master mounts to the steering rack mounts. I believe Audi's solution in the rally days was internal to the cabin of the car instead of the engine bay. - Definitely interested in seeing how you tackle the hydraulic brake booster set up. Some have swapped to vacuum assist from 4000s/Coupe GTs but there are concerns there of maintaining vacuum to the booster while under load. Can't wait to see the progress on this build!

[@rylanclark8221]

It might not look the best but some modern vehicles, such as my 2006 Volvo, use a vacuum pump for when the engine is under load, so that's a possible solution. Otherwise would a vacuum reservoir work? My C4 A6 has two.

[@cuatrokoop32v]

3B, RR, AAN, ABY and ADU intake and exhaust manifolds all fit the "different" 20v heads fine. The 7A and NM heads are the same minus the extra water cooling ports on the intake side, which can be machined in to them (same base castings for all seven engine codes). You can interchange valve covers too, basically just the three different styles. 3B/RR, 7A/NM and AAN/ABY/ADU.

[@theo_korner]

AAN: Make sure to get the crank balanced with the clutch to avoid wear through vibration on the first crank bearing Red Top coil on plug vonversion is a good way to go

[@Mpeterson1286]

This. Also, go buy the crank holder tool. You need it. And you will never get the crank bolt out without either bolting the engine stand down or doing timing with it bolted into the car. That torque spec is crazy.

[@repingers9777]

Not trying to be a hater but when i saw the engine reveal i laughed at how cheap and anemic it looked. It makes the honda K series from his other project look like a beautiful big ferrari engine in comparison lmao, no hate just thought it was funny. I'm excited to see this build that 5 cylinder sound is something i wanna hear in person really bad

[@hazethehides]

As a fellow ocean engine aficionado and former wielder of the torch, I can wholeheartedly recommend an induction heater for those stuck bolts. They're only around $200 these days, and you can really get a lot of heat into exactly where you need it. You also don't run the risk of damaging anything else around.

[@blucheer8743]

Ken block just finished a similar car as a family project everyone be sure to give it up for ken very tragic he was an inspiration to all regardless of the sport.

[@nickpappas4133]

I’m retired Audi tech of 47 years, that motor is a strong piece and never had a problem concern with internals as long as there is oil and coolant in it. I just did regular maintenance including timing belt and tensioner and water pump. There is a special tool to hold front crank pulley and a extension used with a 3/4” breaker bar to loosen bolt and used with a torque wrench for the proper torque,make sure to use locktite on the bolt as it is used as a sealant as well.

[@khourispence8043]

Sometimes ring gaps line up due to a worn spot in the cylinder and the rings move to that spot and stay there. Might be a good move to get it checked at the machine shop. Good luck with the build, love your content 👍

[@RogueViirus12]

Looks like that engine truly sat in a field for a while, at least from the exterior. It's great that the seals (and the residual oil I guess?) held up and kept the internals nice! I'd definitely take a "only have to make the external look pretty" headache over "replace thousands of dollars worth of internals" headache any day. Hopefully the lot gets finished soon so you can get back to wrenching like you love. It's great Byron and Khalil both gave you space in their shop to work this week as well as helped you out with what looked like a nightmare of an engine. I know they're still in the early days of starting up that company which is always rough, and I'm sure they're busy. Great content as always Mike! Excited to see the engine slowly get built back up with bigger and better internals in coming episodes.

[@JonnieB.]

As a new Englander all my life I’ve seen ten year old cars that look like that engine. The contrast of interior vs. exterior is a testament to the quality of 1980’s Audi materials and build standards. Looking forward to the next installment. Media blasting and a hot tank on that block and it will look great!

[@daedalus_20v]

Always gotta roll my eyes when KZbinrs work on anything with surface rust and act like it was raised from the Titanic. Any used engine around here that DOESN'T require a torch to take apart is considered "museum quality."

[@Sarzah]

Having grown up in New England, all that rust brought back so many memories! The struggles are real... I was honestly impressed you only had to destructively remove one part. Can't wait to see this come together!

[@coultl6556]

Just rebuilt my AAN. Go with Supertech valves and springs. Keep stock pistons but upgrade rods is a must. I went with IE rods.

[@robert23497]

I love that you did a video showing off your neighbors work.....and views are views. That said, the quality of work that I have seen on your channel tells me that if you are recommending them......they are better than good. Still. Another great video sir. Thanks

[@Dragehest]

I used to have a S4 with the AAN engine, i changed the old coils to newer coilpacks from a TFSI motor and harness from 034 Motorsport. The engine ran much better and smoother at lower rpm with the newer coilpacks

[@carlmillis9522]

Nice. I have a 1996 S2 Coupe not been on the road for 12 years now. Only done 75k miles. Will be getting that back in action this years. Always good to see anyone one of these classics kept in action

[@jbrentd]

Loving the project. Many of us use a 3B intake manifold and piping in the small chassis, but it's not an absolute must to do so. Just have to check for clearance for the side mount radiator. Oh, and I used the engine teardown on mine to "justify" buying a welder (for the stripped hex heads and sheared bolts), lol.

[@Peteblz1]

The Quattro was my favorite rally car of all time. This is the coolest !

[@parishjohnson5844]

Love the build. For my 1990 Coupe I have the Wagner Tuning intake manifold and intercooler.

[@Steveh817]

Subscribed! Having owned a few 10v and 20v Audis and dreamed of doing such a transplant, I will live vicariously through your build. Hopefully the hiccups will be minimal and the outcome will be magical

[@eurobandit]

I had Jeff Gerner @ four ring performance supplying all my parts for my AAN build i consider him a mentor for these units along as many others in the old 5cyl community, in case you are still looking for pistons, cams and all the necessary parts for the build! ✌🏼 good luck!

[@Cursirr]

Being from the north east I've taken to applying grease and anti seize to every component I come in contact with because of the difficulties of disassembly at a later date. Doesn't hurt to take an extra second to save you from hours of headache in the future even if you live in a fair climate.

[@lobster90hm]

Love watching that engine tear-down. I just know you are going to make that look better than brand new! Such an iconic build, can't wait to see how this turns out.

Great video, from someone who is planning on an engine build it is always fun to see. This will Be the best car in the garage when it’s done. Ur Quattro as stated below was Ken’s daughters choice for her first car. Ken Block is on everyone’s mind and it’s a terrible loss. My heart goes out to his family. It is unbelievable the pain they are enduring as someone who has been in their shoes. Looking forward to what you create here. Tons of aftermarket help in the US here. I’m about to spend some serious $ on my build

[@adrianreyno1]

Like any restoration, it takes time. So, take your time. You want this done right. What's really great is that you got started on the Audi and it's going to be awesome. The Ferrari will be done in time.

[@Shiny_Dragonite]

I loved getting to see an engine teardown. Two this week! Eric over at IDoCars does one every Saturday night. On the subject of crank pulleys... at least you didn't need a forklift and a front-end loader to remove the crank bolt. Can't wait to see this thing go back together. Engine work has always been one of my favorite things.

[@bossplayerunit4563]

that car looks amazing, really good conditon, I'm sort of a purist so I love seeing relatively stock survivors like this one

[@benzina5917]

That block reminded me of the BMW blocks the F1 team in the early 80's used to leave out in the elements to help season them to be more dimensionally stable. You may have a real diamond in the rough there and I'm sure with a little effort you'll have a gem on your hands. As for the rods the discussion begins and ends with Carrillo. They are local to you and hands down the only choice for ultimate reliability.

[@stanceworks]

Amen! On all counts. Rumor has it techs used to pee on the blocks out back to season them further. Should I give this one a spritz?

[@benzina5917]

@@stanceworks I'm sure a little uric acid won't hurt but you'll want to give it a good even coat to avoid differential seasoning of the block which could lead to a crack

[@hazethehides]

@@stanceworks if we ever hear the words "ammonia hardened", we know what you did

[@thebigmacd]

I see the BMW F1 lore has grown legs and escaped reality. The F1 team bought used motors with tons of miles on them. Leaving them out in the weather wouldn't do anything for dimensional stability. It was the heat cycles and vibration from road use that stress-relieved them.

[@Kneedeepingore]

A stock head will easily do 600whp. Also, the stock intake is fairly good, and you should be able to keep it. To be fair, an RS2 manifold with a stock intake with a ballbearing turbo and forged rods and pistons will be enough. You'd make a reliable 500ish whp all day long

[@taylortankersley6325]

Yo Mike, make sure your key on the crank snout didn't just shear off. Audi made a tool for holding the damper when doing a timing belt job on these. I made my own out of a 4ft length of flat steel bar and a 4x4 hub socket cut up to fit inside the damper and allow a socket to pass through. Also absolutely have the machine shop inspect that head for cracks!

[@protodad1]

Bought from Atlanta? More like Atlantis! Super excited about this one. Big Audi fan.

[@k00lkidz4]

I love these old 80s cars, love your channel man 👍👍

[@mediocreman2]

Very excited to see this project. I am a bit surprised that more time wasn't spend researching this engine and how it is laid out, and slightly surprised that shop doesn't have any 3/4" sockets or breaker bar. 30 minutes of research would have saved hours of frustration. Both those things would have made your life MUCH easier than depending intuition, and air and cordless. The only thing that was a surprise to me was the alternator bolt. Someone messed with that before and left you a nice gift. lol Check out the key on the pulley to make sure it's good or get a billet pulley instead. These engines are unfortunately getting harder and harder to find these days as so many 'enthusiasts' hoard parts, and a lot of people gave up on these cars around 10 years ago when they started getting to 2nd hand owners who don't have the financial resources, as well as a lack of mechanics that are not scared of older German cars. Now the cars are in more demand, but it's hard to make up for that lack of parts as well as Audi AG not being willing to ship older parts to the US.

[@jasoncavanagh1048]

Flywheels are really heavy on these engines, so if you get a fluidamper running a lighter flywheel won't bother it at all. If you aren't going to throw a ton of boost at it, run a higher compression piston. An aftermarket I beam rod will be fine. Doing an exhaust manifold would help for ease of servicing if you convert to Vband clamps. It would also allow you to run an anti-lag valve, which not only sounds amazing, but is consistent with how audi modded these cars for racing series.

[@lucasfillman5965]

[@chapel976]

Marc at EFIExpress makes an LS-style coilpack system for AANs and can get you the manifold. I had these on my AAN powered S6 and it was so much better. I had an RS2 turbo and 034 RS2 ECU and it was strong to 32psi of boost and regular 28psi. The N75 was the problem... It's now called EFI Motorsport. $509 for the entire plug and play kit. For $250, they'll sell you one that uses modern factory VW/Audi coil-on-plugs, but the coilpack system is remote mounted so the coilpacks don't overheat on top of the engine

[@draggonhedd]

Hey! You're getting a tiny taste of what its like to work on cars in the rust belt! Almost everything I've worked on here in new england has been like that engine. Knife edge the crank and do what you can to add some oil volume, external oil cooler or something. Lose the coolant/oil heat exchanger on the filter housing, they like to fail and mix coolant and oil. I suggest making a custom intake manifold to run a modern throttle body and make turbo piping as easy as possible. Get rid of all of the electronics strapped to the engine and run modern stuff. That means coils, sensors, trigger system, what have you. Try to avoid VW or audi coils, run something japanese or like, LS coils or somethin. I remember there being some other things you can do to the block or crank or head or something to make it better or more reliable but i cannot remember what. add a Windage tray if it doesnt have one already

The intake you can use that is found easier state side for small chassis is a 3b intake manifold that comes in 20vt Audi 200 Quattros. They can be had for about 400 bucks or you can get a s2 or rs2 intake from over seas.Also when you go back together threat the cam bolt in by hand then torque or you run the risk of shearing the key and also be sure to check the crank cog pulley for cracks. Check out efiexpress they have some stuff for old Audi 5 pots. Stand alone can go vems or maxxecu or could do like Nick ( amdisthebest) on his Audi 200 and do syvecs with a whole custom harness and set up

If you want an intake manifold that fits, is practical, looks stock but can displace a 1000 horsepower and uses all stock sensor search for the Wagner reverse intake manifold.

To fit into small chassis vehicle there are a lot of parts that are different. Use parts from 3B, ABY or ADU engines.
