- MK3/MK4 8v Deep Dive Info:
ABA:
Bore Diameter: 82.5 mm (3.25 in.)
Stroke: 92.8 mm (3.65 in.)
rod, ABA:159mm
Compression Ratio: 10:1
Horsepower: 115 @ 5,400 rpm
Torque: 122 ft-lb @ 3,200 rpm
OBD1 ABA's through 95 had forged cranks, under piston oil squirters and the dual valve spring heads, this allows for a cam with more lift without getting spring bind. Some had EGR, but that only made a small difference in the intake manny and management.
OD2's engines came out in 1996. OBD2 ABA's lost the good crank and squirters, went to a single valve spring design, and had a hole in the head for the smog pump.
The OBD1 ABA is an amazing engine to turbo. Rumor has it, VW originally set-out to design a turbo engine when they ran out of time / funding and decided to up the compression (with different pistons) and use it as a torquey N/A 4 cyl. Who knows if that story is true ... it certainly is possible as it is very unusual for a 115hp VW to have oil squirters ...!
AEG, AVH, AZG:
Bore diameter: 82.5 mm (3.25 in.)
Stroke: 92.8 mm (3.65 in.)
rod, AEG:141mm
Compression Ratio: 10:1
Horsepower: 115 @ 5,200 rpm
Torque: 122 ft-lb @ 2,600 rpm
the stroke length is maintained through different wrist pin heights and the shorter block (ie aba’s deck height change is equal to the change in rod length). Thus the shorter rod creates better low down torque but the ABA will rev better and make a wider torque curve (higher in the RPM band).
AEG heads do have swirl ports though… The intent is to swirl the mixture as a way to help it fill the cylinder at lower rpms. Its believed that this is one of the reasons the AEG makes better low-end torque than the ABA. However, the shorter deck and larger bore the the AEG is the primary reason for the greater torque though; this intake design is just a way to help fill the cylinders because of the shorter stroke.
Basically, the biggest difference comes in the power curves. The AEG+ engines give more torque and horsepower at the lower rpms. Mostly this is due to different camshaft profiles and the individual intake manifold runners compared to plenum in (MK3). The torque and hp actually comes LATER in the rpm range due to the different manifolds and the camshaft profiles! The MK4 intake manifold is longer and has individual runners. The longer the intake manifold runners, the earlier the torque comes. The shorter the runners the later the torque comes.
The AEG cylinder head is nothing more than a modified cast of the ABA placed on a 1.8T 06A block. Thats right,it is the block that has the 3 oil return drains in it NOT THE HEAD
Other Notes:
The AEG cross-flow is not a tall block, dropping back to 220mm like the earlier block (1.8). Suspect this was to enable it to fit the more aerodynamic hood lines that are becoming fashionable. Bore spacing, head-bolt pattern and all of that stuff is the same, but that's about where the similarities end.
The tall-block ABA cross-flow motor was transitional, and would bolt into a mk1 Rabbit. No such luck with the AEG-motor. There are no provisions for a front motor mount and no provisions for a side mount - in fact, there are no provisions for the MkI/MKII motor mounts at all. There is no intermediate shaft, and thus no distributor- and no place for one. The MkIV cars all have a coil-pack ignition, and since you can't add a distributor, you would have to swap the whole ignition system over to use this motor in an earlier car.
ABA’s have external water pump, intermediate shaft driven oil pump and distributor
AEG has a timing belt driven water pump and a chain driven oil pump thats built into the front of the engine, Audi style. Because of that, the AEG crank is not interchangeable with previous motors. It's a heavy cast crank, so serious, high-revving performance mods are probably not a good idea. The water pump is all in the block, and there is a different style of oil pan. The cylinder head bolts are 10mm diameter rather than 11mm.
Can you swap a AEG head on a ABA bottom end?
The AEG 8V head has the same 5 oil drain holes that the 20V heads have. You will hear a lot that, If you want to put it on an ABA block you will have to plug the three middle holes. However, this is not true! It is true only on the 20V head because the 20V head sticks out over the block, the 8V does not...
I believe its best to run dual valve springs on the OBD1 ABA head either way. This head seems to be the best flowing, least extra work head to use. Using the AEG head the manifolds should be fine, but since its on an aba anything you buy in the way of exhaust should be tailored to an ABA because of it's taller block.
In summary of AEG head on ABA… If it's an OBD2 ABA it wouldn't be any difference. If you have an OBD1 head, then I would stick with that over an AEG. - Авто та транспорт
my scirocco is a 95 aba block and head. 97 obd2 management. 268 cam and chip, techtonics 4 to1 race header. poly mounts. 1900 lbs with me in it. lots of fun.
Cant wait to watch this one in bed tonight...I'm extremely tempted to take the VR6 out of my cabriolet and do a 20v turbo set up but cash flow is always the problem lol
Thumbs up from Cape town South Africa
Hahaha cashflow always gets in the way doesn’t it! Still planning out my 20v swap as well into the EA cab… stay tuned for that hopefully sooner than later! Appreciate the support as always! Cheers!
The 8V is efficient, simple and bulletproof. Performance engine it is not, but for those of us who don’t care, it’s great.
Man, what a walk down memory lane. I miss working on ABA 8Vs. Love these bullet proof little motors.
this engine is a tough SOB too, really holds up to punishment and neglect.
Yup, that is the recipe:
Cam
Chip
Header
Cat Back
Light Weight Crank Pulley
MK4 Intake
10mm Spark Plug Wires
If you have time, add M90 using G60 bracket
****I did not know about the lifters. Cool tip.
I learn something in every video. Appreciate you taking the time to explain the differences.
The ABA with its longer rods makes it a smoother and more refined motor. I prefer the ABA because of this.
I like stepping outside the norm nice job
I did that suspension uplift that you did on that vehicle and I love it thank you on mine
Very interesting episode Ry. No doubt you spent a ton of time doing your homework. Looking forward to the next episode to see the gains. Appreciate your energy and time into this channel, always stoked to see whats next. Dig the Hot Rodding aspect of this build.........cheers
Thinking right out the box there 👍look forward to seeing the outcome 😎
Here in South Africa we have a lot of 8v's and i have to say these 8v's can make a lot of power on a budget, you just need to know how. Like me i always had 8v's for more than 10years and only building a 1.8T now but keeping one of my cars 8v.
Howsit bro. I live in durban. I have a 1.8i citirox. Yes 1.8. Bzf. Upgraded version of the velociti motor. I have 276 cam. Full exhaust. Dicktator. I make 92kw flywheel. 186nm. Rest of motor is stock. What can I do to get her up to about 100/102 kw?
How to hot rod a 8v, vr6 swap it
Hahha kidding good video
Great stuff!
Excellent video
Watching from Ireland 🇮🇪
Currently building an AGG 2.0 8v with similar mods
Keep up the good work 😉
wow. I'm glad I found you. super informative.
I’ve been waiting for this! Love your channel 👍👍
Thank you, thank you!!! Appreciate the support and thanks for watching! Cheers!!
one of the best teachers I had always said "if it has threads, bolt or screw head..its supposed to be played with" in regards too the safety wire on the fuel delivery or advance on diesel injection pumps. i wasn't into Vw's at the time but he said he had a lot of IDI tuning tips, i missed out on that but i always appreciate this kind of video, im on my second ABA, a late 98 GL that is getting a cam after learning all this. all praise TTuing, i just installed their short shift kit 👌
I am have an OBD 2 ABA installed in my MK1 caddy.
Cool video, it took me back 15-20 years ago !! I had a MK3 2.0l NA, that could keep up with my friend MK4 Vr6, but mine was so much fun to drive because so much light and responsive. There's nothing like NA light car feeling...had to sell the car to move to Europe, I wish I could have kept it !
I stand by the ABA being the best bang for your buck swap in a mk1/mk2 . Especially if you're just building a gnarly daily driver .
They can be built for power for cheap too . Guys have 550+ hp turbo builds . Iirc the fastest 8v in the world is in Brazil and does a 8.9 in the 1/4
As for the fuel rail and injectors ... I just used the aba ones in the mk4 intake
Is the AVH reliable enough to turbo and push around 250?
@@doreetoes69 yep. Should be able to handle 250 with the right supporting mods
@@VWarmyhow about aba how much can a bone stock motor run reliably? I know they make aftermarket pistons and rod setups that drop the compression
I’m custom building a whole setup with an Eaton supercharger on my mk2 aba swapped golf. So excited to finish it!
So much information such a great video and if you love cars .... really appreciate your videos man keep up the awesome content ☝️😎🙏
Sick car man!
Major flashbacks. I had a Mk1 GTI in that same color with that motor in it. Miss that car
love your show
all the way from south Africa 👍
Hoyaa...I'm from Cape Town
that makes 3 of us lolll
Love it, thank you so much! Thanks again for all the 🇿🇦 support!!! Cheers to each of you!
I did an 2.0l aba swap into my mk2 golf a few years back and know some tricks. I got 165hp at the flywheel.All na power.
I had my fun with this motor in various iterations in the early 2000's both NA and Turbo. Takes me back a bit.. It will be fun to watch. I can tell you the 6A black is very similar to the 3A 2L 8v block with 144mm rods. Torque did come quicker how ever they didn't rev like the ABA. I'm grabbing my popcorn now :)
Hahahah love it!! Cheers, appreciate the watch and support! All these iterations are so cool to deep dive into!!
Us in VW of America got screwed with the ABA where as Europe got the ABF 16v. Was widely covered in Sport Compart Car and European Car magazine BITD how great the ABF was in Europe and how terrible the ABA was that we got. "Underpowered" and "gut less" were widely used. We got the VR6 later but too late. I went from Mk2 to a later Mk4 and skipped the 3rd generation entirely.....until recently. Now I own a proper 1994 LHD ABF GTI here in the USA and love it. Evolved 16V engine with more modern management, Recaro seats, textured mouldings and flares, etc....reminds me of my old 1992 GTI 16V in many ways. Looking back now, the ABA engine is pretty unique in that the rest of the world got the counterflow head 2E engine similar to the 3A we saw in some Audi engines.
I have 2 MK4 Golf GLS, 1.8T Brazil built and a 2.0 AEG German built and I would love to do a comparison between the cost of modifying both engines vs the cost and gains. the AEG engines shares most of the parts of the 1.8T internals (con rods, valves, springs, oil pump, etc.) the obvious difference is the cylinder head/ amount of valves and only one camshaft. I personally think the 2.0 8v has as much potential as the 1.8T being they are extremely similar overall. the cylinder head may not flow as much air as the 20V but just because there are more valves it does not mean it cant be ported and fitted with OS valves to get better flow.
Ya I love it all, there’s so many things to review or look at when you start down this rabbit hole but I love it hahaha!! Thanks for watching, truly appreciate the support! Cheers
Hey Noel! Which motor has the most miles on it! I have a Golf GLS 2.0 AEG BRAZIL BUILT. Reaching 191.3k miles and Im happy owned it for 6 months.
@@TePasasALV The AEG have the highest mileage at 205K miles and the most reliable. The 2.0 8V get ragged for being slow but they are great for a daily commuter.
Thanks, I'm kinda doing something similar, I just didn't know much
About headers, I have a tri y that I ran on the ABA/JH setup. It measures 19 1/2" total height and has a sway bar kickout.
Fit better than a short deck
Dump the factory fuel injection and install mega squirt. Also add a short runner intake manifold.
Isn't the short runner gonna push the peak hp higher up? These cars are already slow in city traffic I wouldn't want to lose any power in the low revs even if it means higher top speed.
A UA-camr by the name of memphis, did a 2.0 ABA swap on carbs....
Yes yes! Good videos too! Thanks for watching, appreciate the support!!
Gti/gli/gtx 2.0 16v have oil squirters under the pistons too for only 130ish hp. Pretty sure they work based on oil pressure so they not flowing at idle but once rpms/pressure goes they work. My guess is to reduce wear over time, especially when its designed to have people rev out the car to get the most enjoyment
Very true, also has cooling properties too when you pushing the engine hard (especially if it’s boosted) which is why it tends to lead in that direction! Appreciate the comments and support as always!! Cheers!!
Great video today, I didn't know that there that many differences between the 2.0 litter 4 cylinder engines that VW used in these cars.. I'm really looking forward to seeing how much horsepower you get out of this combination.o VW engine parts in the next video.
You are now one of our references and inspiration as we start our MK1 Scirocco hill climb (Berg Cup) car. Full on dry sump 2.0 aba w/ 16v head turbocharged port polish etc etc. Shooting for 650 hp screamer 9k rpm interrupter...thoughts? Love your videos.
Nice video as always 👍🏼 I must be honest that here in Europe I've not heard that about an 8V turbo being on the cards, maybe why the ABA and the non crossflow 2E here in Europe have those cranks and oil squirters is mainly due to cost cutting, as the ABF has the same block and crank and so no point going to the extra effort and cost of making a cheaper crank or another block casting with no oil squirters. I have heard that the ABF was meant to have 170ps and the VR6 was meant to be a 200ps 24v, but the early heads cracked so the 12v TDI head was used instead, so vr6 had 174ps and the ABF dropped to 150ps.
Yes not a type o, TDI vr6 👍🏼
Ya see, we never had the ABF in any form, so for us the view always has a bit of a different turn, which is why the “internets” always loves to throw in oppinion hahaha! But I love it! All the cool variations around the world using roughly the same parts is so cool to me! Probably the part I enjoy the most about this hobby. Endless endless Lego options!! Appreciate the support as always, big fan too btw! Keep up the great work!! Cheers from this side of the pond!
HEY! MG! really good video!
I have a mk4 AEG 2.0 in my `81 mk1. I want to swap the 2.0 head for the 1.8t head (manifold, turbo, etc) , do i have to change pistons and rods? or can i use the original pistons and rods that came in the 2.0?
Thanks Mystery I never knew about the stock 8v dual valvesprings. Are they stiffer than 16v stock springs? I wonder if they will work for a high rev 16v cam setup…
🔥🔥🔥🔥🔥
🙏🙏🙏 cheers appreciate the watch and support!!
What heater hose is that off the head to the top of the rad?
I guess my next build is gonna be a 2.0 aba cabriolet 😁 on boost🏎💨💨💨💨💨💨
say no to cabriolets!
Don't use the mk3.5 the ecu and wiring is a pain when it comes to tuning
I do not care much about the street / rain noise since info you provide is priceless. I have Jetta 2001 with 2.0 L engine, still runs great, it is smoking at the cold start and i have to add about a liter of oil every couple of months. Would you know what needs to be fixed to eliminate consumption of oil. Thanks and greeting from sunny but cold Ontario
Appreciate that, thank you! Could be a lot of things it’s hard to tell without being there. Does it also smoke under deceleration? Under Acceleration? Idle? Does the engine have higher kms? Lol lots of questions to ask, but either way, thanks for watching, really appreciate the support! Cheers!!
Use mk3 injecs n fuel rail double up nozzle tip orings and spacer to mount rail to intake and ur good
I have a question! I have a 1986 convertible rabbit, need to put an engine with trans... what engine and year you can recomend?
Every aba I've had has been stupid reliable.... ac pw steering delete, mk4 intake and exhuast manifold some sort or chip underdrive pulley.... make a fun daily reliable 30+ mpg car... oh yea even better if you get the scientific rabbit ported mk4 intake
Very nice video !! I have some questions about EGR doesn’t get deleted?
Love the color of the car! What is the paint?
My MK5 Jetta has this 2.0 8v motor. engine code is BJZ
tons of infos added :) , 1.6 mpi can accept the mk4 aluminium intake and roker cover? from what i see they might , also the tt cam is from an early audi TT?
wow its been to long sinds ive seen youre videos almost a year. i have some requests on the piston rings of a 2H engine mine seem to be some wat stuck in the piston i dont have a place to realy work on the car but i want to loosen them up. It has a few kilometers on it over 300k but it still does what i want daily. I did get some new shoes for it the snow flakes. Any way i heard ATF is a good one but how do i get that out off the block? and how do i do a timing belt job? love the channel and the cars!! Also wen my engine quits im doing an ABA and on youre recommendation an OBD1.
Is it possible to use a 2.0 block with a 1.9tdi head ?
Have and idea where i may find a ABA Engine very simple Electric wiring diagram to run it in my westfalia . I read somewhere on the web that only few connections and wiring could run the Engine , without all unnecessery wires.
12:45 torque peak drop to 2600 rpm because of the cam.
So if I'm hearing correct the 06a na doesn't bolt into a mk1 ? Or am I hearing things ...?
Pardon my ignorance but the mrk lll 2.0 aba motor comes from a 95-98 Jetta right?
Yes
Can you put an ABA bottom end with an MK4 obd2 top end?
Well i dont know about the mk4 but if the timing belt comes to snap, on an early aba, the valves and piston don't come in contact.
I have an OBD1 swapped ABA into my mk2. Looking to turbo but can’t find a good ecu mgmt system / tune :-(
Very very interesting, I'm go swap 1.8 mk1 automatic for something like you do with this. I have in Guadalajara Mx. Atlantic 86 , were a can found motor ,transmission standard, brackets and all that I need ?? Can you help me??
Thank from Ontario Ca.
Can you make a 16v from a 8v engine? If so what you need to change en what would be de price from something like that
I’m swapping an MK2 16V on mu AEG
People sleep on those mkIVs all day.
Serious question: what's up with the ABF clone?
I want to Weber my aba obd2 how can I deal with timing advance?
I have a 2.0 ABA 8 valve with digifant 1 fuel management from a corrado in a Mk2 Scirrocco works great lots of torque. Unfortunately o2 sensor shorted out and fried my ECU. If anyone has one kicking around 😢 shoot me a message.
I can't seem to find the final episode. Can someone help me ? I got blue balls right now
what is your opinion on swapping the 8v ABA head to a 16v ABF or possibly KR?
Hahaha oh boy! That’s interesting! Personally, I’d stick with the 16v head, love them and I personally believe they are far superior to the 8v Aba head. Again, internet may chime in differently. But again my opinion! Appreciate the watch and thanks so much for the support! Cheers
@@MysteryGarage I think I worded that wrong, meant putting a 16v head on an 8v block but I’m sure plenty drag guys prefer 8v to 16v because of the quicker torque delivery off the line
@@mk1maad oh you absolutely can. Look at the videos on my ABF clone build I started. That’s exactly what that is, aba tall block with a 16v head. (ABF clone)
@@MysteryGarage will definitely do.
A lot of guys in South Africa run the KR 16v head on the 8V bottom end for low cost turbo builds as it drops the compression ration to 8.5:1, runs at low boost but plenty of power for a MK1 because of the weight.
I have questions about doing this swap and can’t seem to find a clear answer if you have an Instagram or email I can ask you these questions that would be great
Absolutely! @mk1build on insta or support@mystergarageshop.com. Thanks for watching! Much appreciated! Cheers
Can't you just use the lower intake manifold from The Mark 3 and the upper from The Mark 4 then you can keep your injectors
Nope totally different
ABA engine... 159mm connecting rods , EA113 engine... 144mm connecting rods. Maybe is not a good choice change this engine... Maybe!
