Great video with up to date info and clear video quality explaining the interchangeability of the parts. Because I have a 1986 Audi Coupe GT Commemorative Edition with the digital instrument cluster (2.2L), I also have a 1993 UrS4 with the AAN 20v turbo engine and three 90 Coupe Quattros with the 3B 20v turbo engines. I really want to place the AAN engine in my Coupe GT ( I know it's going to be a pain since I will have to deal with fitment issues like radiator & intake manifold). and with the UrS4 I want to place a 3B engine in there and sell the UrS4. Your video perfectly explained how I can place a 3B head with intake manifold to fit the AAN engine on a smaller chassis, which is giving me more of a green light for the swap. If I can't get my hands on a UrQuattro, then I might as well convert my Coupe GT to the S1 right off the bat. Unless I get lucky and find a 200 avant with the AAN engine thus saving me from butchering the UrS4 for it's engine. In the end I my UrS4 runs and drives as well as 1 CQ supposedly runs and drives, while the other CQ has half of the engine accessories removed, while my 3rd CQ has no engine at the moment. One of my CQ in red color might be sold for scrap or as a shell since that's the only car I have with serve rust damage, I plan to remove the fully intact engine and drop the 3B into my Yellow CQ with a full on S2 conversion. As with the 3rd CQ black color, the trunks of all the cars came with all the parts needed to rebuild that 3A as well as I have a Diesel K27 Turbo 5 cylinder engine (from a 1987 I believe the year is correct) top which I'll source out parts from it. Any advice about all of this and interchangeability of the diesel parts towards the gas powered engines. I also live in South Florida. Thank you and sorry for the long message lol
😂 man you sound like me thinking about all the Audis I have and how to swap and sell. I have a Coupe GT roller that I got for $100. I found the entire dash in the trunk minus the digital instrument cluster which I want to put in my Sport replica along with my MM commemorative seats that are shredded
Hey man great content really enjoying your videos. It's tough to find info on these cars and I appreciate you sharing your knowledge. Was looking for a project car and kind of fell into a 1990 Audi CQ. Spent the last year getting it running. Getting a lot of ideas from your videos.
All three have forged rods, 3B & AAN have different water manifolds... 7A is pretty much a 5cyl version of the VW 16V, also the 7A intake has very long runners to help with low and midrange torque, even so, it's still weak on the bottom end and I believe the torque peak is @ 4000 rpm.
@@shone190 they are the same rods that are found in the 16v aba motor, they are forged, but not able to stand the same amount of power as an aftermarket h beam
Hi there! Thank you for the video, it helps a lot to understand the differences. I currently have a 91 Coupe Quattro with a 7A. Since it is too hard to find an ANN or a 3B, I am thinking on pulling the 7A and work on adding sleeves to it. For what I can see, all I would need is the water manifold and the oil filter housing, other than this I can pretty much keep the 7A and add a turbo to it. Does this sound correct to you?
@@harm1727r don’t know if I mentioned it in the video, but you can use the 7a long block, buy larger pistons for turbo use, no need for sleeves. The oil housing will bolt straight on, and the head can be machined for the correct water manifold
@@BrokenQuattros Thanks for following up, I almost forgot the block is the same, so I agreed with you, no need for sleeves, although I do want to get at least 500hp to the wheels but from what I have seen these blocks would manage easily. When you say "larger" pistons I think you are talking about the diameter of the piston, correct? If this is the case I would have to bore the engine block to what diameter? Sorry for so many questions, but I am grateful you are willing to help. Thanks!
@@mattdaman5182 Hi Matt! I am in the process of pulling the engine out, actually, I decided to pull everything out. I might post some pics and videos, but I don't have the luxury to film while working on it, it is a challenge though but not impossible.
Great video, I've a 20v b3 coupe quattro here in Ireland with the 7a engine and although it's a good bit weaker than the turbo I love it. Any tips for getting extra power from the 7 while keeping it NA such as on the intake side, MAF sensor or cams
Brilliant, clear, concise video. Thank you for sharing your knowledge 👍 I have an early spec 90 20v (7A) here in the UK (bag of snakes, Hitachi ISV & 2 pin ECU). Love the car - had it over 20 years now! Did a later spec 7A also exist in the US with the cast exhaust manifold, Bosch ISV & 4 pin ECU? In Europe from about March 1990, Audi replaced the beautiful tubular exhaust manifold for a cast one and claimed the same power output (170hp), stating the revised ECU made up for any power loss. Never quite believed that! Makes me wonder what they actually did with the later ECU to make up the difference... If the ECU could be tweaked that easily, why didn't they do that first of all? Could the early 7A have power in reserve waiting to be unlocked...? Lots of rhetorical questions - perhaps we'll never know! Keep up the great work flying the classic Audi flag! ☺️
i got 7a engine i planning to put this engine on audi a4 b6 but i told i can use the abk ecu from audi 80 b4 to run this motor the ecu controls all injectors by one wire so i can add one injector wiring and the best simple thing there is no crank sensor for this ecu its only hall sensor on the distributor so what you think i am doing this cuz i love 5 cylinder sound and i love the a4 b6 how its looks and style
I have seen 5 cyl swaps into b5 and b6 chassis, but you run into radiator problems, the engine is longer than v6 and i4 motors so space becomes a concern. Having never done the swap i dont have a lot of input
This was an awesome video, definitely have a lot more knowledge to do my research on! I've been struggling to find good info/writeup's on these engines. Here's a question you may or may not know the answer to, do you know if there are similarities between the underbodies of the B2 and B3? I'm looking into doing a Quattro swap on my Coupe GT, I know the Audi 4000Q is a good candidate but I have the opportunity to buy a very beat up (but still running) B3 Quattro for very cheap haha. Also what forum should I join for other 5 banger Audi related questions?
The project pad or s2forum are the only semi active forums for these, quattroworld is too, but not as good for these types of research. The coupe gt front end is mostly the same as the 4000 and b3, however it lacks a tunnel for a driveshaft to the rear and has a completely different floor plan. It is NOT a simple swap by any stretch of the imagination, it requires extreme fabrication, many have attempted, i cant think of any that have completed it, i know of a few latvian ones that i think might have started as a fwd model, but nothing that sticks out.
@@BrokenQuattros Oh I know its not a simple endeavor but when is anything great simple? Haha, thanks for the pointers man I'll go check those sites out!
Very well explained. Ive been looking at aan swapping my coupe quattro. Just wondering if keeping the serpentine belt is easy to do? I prefer the serpentine set up but am not sure how it works space wise and with power steering pump pressures.
Serp belt is an easier setup, but with your coupe its much easier to keep the 7a balancer and all the 7a accessories, you wont have to change any of them if you run a 3b/aby intake setup
I was thinking of just having a friend of mine reeled the throttle flange further to the front of the intake to clear the radiator. Do you know if the rack and the aan steering pump will work together? I already converted the coupe to vaccume brakes so all it has to do is run the steering.
You said if your looking at bigger power (500+) use the 7a, is that because the block and head is stronger Than the aan… reason I ask is because I have a 1990 coupe Quattro with the 7a engine that runs sweet and was debating just getting rid to buy an already turbo’d AAN.. had no idea the 7a was so strong… Thanks for the video, learnt a lot From England, West Midlands Thanks
Let’s back up. The head is not stronger, they are the same castings. But because it’s naturally aspirated, they usually are in better condition and don’t have the cracks from heat cycles, compared to turbo versions. I thought I said if you are looking for 600+whp because that’s where you will lose stock aan pistons. So if you are going for more power than that, you will need pistons and rods. Which is why you should just build the 7a at that point.
Hey bud, I came across your video while watching group B content. I am looking for a engine harness and ecu for a 3b. Let me know if you can help. Thanks and keep up the great vids!
Hi Dave I'm coming to the last stages of turboing my audi 90Q 7A motor and I'm having problems 😅 I was going to use the 7A intake but have decided against it for space reasons so I bought a AAN intake manifold and the water manifold too, now here comes the problem it has hydraulic servo on it wich means to powersteeing pump is lager and leaves me with no space for water outlet/ manifold any oem parts to get around this problem? Cheers love the vids👌🏻
This is one of the big issues of mix and match. For oem options, an aby or 3b intake manifold with 3b or aby water manifold will work. The problem with the aan stuff is its made for a front mount radiator. Your side mount radiator will hit the aan intake manifold. So you can switch to 3b intake/water manifolds, or you can convert to a front mount radiator (custom fsns and stuff will be needed). If youre trying to move your power steering pump you can convert it to an electric pump from like a second gen mr2, lots of different ways to approach the problem, oe solutions are the easist but not always the easiest to source and buy
@@BrokenQuattros OK food for thought👍🏻, trying to source 3b or aby parts here in Europe is super expensive did look at those intakes and they're up in the 600 to 1300 ££ pounds region for those, I was thinking of modifying the intake by moving the TB to the front of intake and using the 7A TB as again sourcing the parts needed is not easy. Would a 3B water manifold fit with a AAN intake?
@@audihughes3999 yes the 3b watermanifold should fit with the aan intake, if youre moving the throttle body on the aan that works too. If you have fabrication at your disposal, many people also modify their aan water manifold to have the outlet in the middle

@@BrokenQuattros Yes you did- I was wondering about some of the other ancillaries that are different. Also on you CQ build is there a reason you are not using a BST style reverse intake?

I've read various forums so I'm reasonably informed just thought you might have some insight on going with the AAN platform and having flexibility to fit into different chassis- Cheers
@@jdmimportlogistics nothing wrong with the BST manifold, you gotta use what you can find and what’s available, I like to use OEM parts to cut down on fabrication needs, custom intakes can require custom plumbing and custom work to make it all fit, nothing wrong with that if you have the tools at your disposal
The aan oil pan is not made to accommodate a side mounted radiator. The oil pan will occupy the space where the bottom of the radiator should sit if you are putting it in the OEM location. The 7a/3b oil pan is offset and has additional capacity pushed to the other side of the pan allowing for space for a side mounted radiator.
I know this is a very old video, But if I have my 3b engine can I use a AAN block. Are the bolt holes there to attach the P/S pump bracket and the Alternator? assuming I have all my parts off the 3b it should be able to plop in the 200 correct?
@@BrokenQuattros Awesome!!!!thank you for the fast reply. I was thinking about this today and was second guessing myself. The AAN has a oil windage tray girdle as well correct little bit more strength? I'm about to get my Lago 200 20qvt back up and going
I have a C4 S6. I looked on Ebay for RS2 Exhaust manifolds and there are several aftermarket ones. Is there any manufacturer that you would suggest over an other ? AND are these even the same kind of design as the original RS2 ? thanks
Wouldnt probably fit unless the aluminum radiator is super small or oddly shapped. Many people will cut an aan manifold and move the throttle body further down the plenum and reweld it
Easiest way is the factory way, remove a freeze plug from the block and add in the nipple style fitting, 035103111b, still available from the dealer. Then you have your feed!
Well, assuming you want less than 500awhp, cheapest is gunna have to do with your skill set. 034 does sell a 7a turbo kit which is probably cheapest if you dont have experience or skills to build. But a donor car is usually the cheapest route. So a 200 20v, urs4, or urs6 as a donor car assuming you can find one for 2k or less and you can do some minor fab and swapping and some wiring stuff thats going to be the cheapest.
That’s kinda relative. In the USA the 3b is probably the most rare since it was in 1 model for 1 year. But that motor is in more cars internationally (Audi s2, and the rr Urq which is basically the same setup). AAN is probably the highest production in the USA and world. But also the most desirable
So basically the aan belt wont work on the 7a block because its missing a bolt hole.... Can it still be drilled on the 7a? Or is the block casting totally different that it won't accommodate the ribbed belt setup bracket?
@@hybrid_hatch9497 I'm currently trying to get an ur s4 c4... The original AAN is missing the head. Would the 7A head work out fine? How would I get a hall sender kit here in south Africa?

@@lhmllr the aby and aan long blocks are the same. The only differences are in the manifolds and misc parts that are bolted onto it.
Great video!! Can you provide contact information? 7A turbo built in progress.
Should be under the profile, but brokenquattros@gmail.com works
Have you used your 3B or AAN engine?Considering selling or no
No plans on selling, sorry
I have a 7a and I want to turbo it what’s the cheapest way to do it
Well, assuming you want less than 500awhp, cheapest is gunna have to do with your skill set. 034 does sell a 7a turbo kit which is probably cheapest if you dont have experience or skills to build. But a donor car is usually the cheapest route. So a 200 20v, urs4, or urs6 as a donor car assuming you can find one for 2k or less and you can do some minor fab and swapping and some wiring stuff thats going to be the cheapest.
Better engines than modern tfsi.
@@sinmoto1220 oh yeah! Much better built, much more reliable, will out live them all
Do you know if a mc2 oil housing will bolt up to a 7a?
It should, casting is the same
@@BrokenQuattros awesome! Thanks for the reply!
I had to recycle a snake manifold because I had not known anyone that had a 5 cylinder na 😔
What is more rare
That’s kinda relative. In the USA the 3b is probably the most rare since it was in 1 model for 1 year. But that motor is in more cars internationally (Audi s2, and the rr Urq which is basically the same setup). AAN is probably the highest production in the USA and world. But also the most desirable
Hi I have a Audi 200 2.1 turbo Quattro 184 hp. Would it be possible to swap a AAN engine in my 200 Quattro?
So basically the aan belt wont work on the 7a block because its missing a bolt hole.... Can it still be drilled on the 7a? Or is the block casting totally different that it won't accommodate the ribbed belt setup bracket?
Block is missing the place where to drill and tap. I think it would probably still work without the one bolt.
@@hybrid_hatch9497 I'm currently trying to get an ur s4 c4... The original AAN is missing the head. Would the 7A head work out fine? How would I get a hall sender kit here in south Africa?
