Morning guys,
Just wondering if anyone could give me some informations regarding turboing the ACE engine fitted in the Audi 80. Really wanting a bit more 'umph!' but not really got the time to do a full 1.8T swap.
Has anyone done a conversion on the ACE engine?
I believe its pretty much the same as the 9A and ABF engine in Goof's and Corrado's?
What bits are needed other than the obvious bits?
Can K-jet deal with upped power?
Will I need to upgrade internals?
What sort of boost could I run with standard internals? (was only really thinking half a bar?)
Any help/advice would be greatly recieved!
Cheers,
Andy

I've heard it said before that K-jet injection doesn't like turbos, but I can't see any real reason why it wouldn't work as a 'suck through' system, providing that it still has the capacity to provide the extra fuel required.
If you're looing at running on standard internals then you'll only be able to run low pressure anyways.
That's about all i can advise as I know nothing specific about the engines you've got!

If its the same K jet that used to be on Fords there were a number of extra gadgets that had to be fitted to allow then to run turbos, 2.8 sierras and capris spring to mind, i think the bit for the metering head is the bit thats very hard to find these days, but the ol memory is a bit foggy.

Volvo back as my main squeeze, more boost and some interior goodies on the way.

I would fit a corrado G60 engine, ive done this to an 80 coupe in the past and it was quite easy tbh.
Turboing an n/a making exhaust parts, getting it to fuel right, ect ect and will the clutch take it?....more hassle than you need..
I can get you a G60 engine and other bits, not sure if i can get loom tho.

Didn't even think of the G60 engine!
How did you go for the the engine mounts on the G60 engine in the coupe?
Dude, your avant looks mint!

The 924 Turbo does indeed run K-jet as 'suck through' .
The metering head, warm up regulator, and dizzy setup are all turbo specific.
Oh and the injectors are screw in rather than push in.
You can problably find all the gubbins off a Series 1 924 Turbo (<1980) without much fuss and it'll probably all swap in directly for your components. Simply add a turbo...

I'm not convinced by the logic of doing this because you don't have time to fit a 1.8t. Provided you used an A4 engine so everything's already inline, then other than the management I'd expect fitting the 1.8t to be less problematic, involve less custom parts, and result in more power and a much nicer delivery than turboing the current engine, and importantly, be much more reliable once done. If you do go ahead with turboing the current lump it'll be an interesting project, but personally I'd expect the 1.8t to be an easier conversion, so be sure of your reasoning behind doing this.

I didn't just mean time. I meant time and effort. using the exisiting engine everything is already in place, all the bits are available and I can leave the engine in the bay on its mounts.
If I do a 1.8T swap, I'd buy an A4, have to take the engine out along with all other bits required, take the engine out of the 80 along with all other bits not required, mount the A4 engine in along with all the other new bits.
I kno the 1.8T is a better idea but would take me more than a wk. keeping the original engine I could do it all in under a week I rekon.
I don't expect any of this to happen soon so its more than likely i'll go the 1.8T route, I was just asking about the 2.0 16v idea.

Fair play. Like I said, it'd be an interesting/cool project anyway, I just wasn't sure of the reasoning. Having pulled a 1.8t out of a Passat before I'd still maintain that the 1.8t would be a quicker swap, they're quite an easy engine to remove if you're methodical about it all. Fair point about the time to break an A4 if you wanted to do it that way, but I'm sure you could buy an already removed engine/box/other bits for less than the money you'd spend on turboing the 2l, they're getting cheep recently.
Either way, it sounds like a really interesting project, and should be great fun. I do have a big soft spot for these Audi's.

You could go down the route of having the 2.0 ACE with a turbo and run it on G60 management with a SNS or similar remap for Turbo application.
If you source a G60 ECU, loom and injectors then you will need a turbo, exhaust manifold, intercooler (+ pipework) and you may find that using a cut down audi S2 inlet manifold is a good option.

The turbo fords ran KE-Jetronic with the little electromagnetic actuator on the side to control fuelling along with both an ignition and fuel ECU.
Very few bother with this system now most preferring to convert to efi instead as even the newest rs' they were fitted too are touching 22 years old and it could be a problematic system back in the 90's when I was messing with it.
The Porsche mentioned above was 1981 so that's even older!!!
HOWEVER.
from memory the old Audi turbos are k/ke jet and should be an easier swap then.
Personally I'd go for standalone management,yes it's more pricey initially but a lot easier to tune,set up and fault find on plus I believe second hand systems are pretty reasonable now.

KR and 9a engines have been turbo'd for years - in fact for a long time they were preferred by the Americans and Germans for higher power setups through the belief (right or wrong I couldn't say) that they are stronger lumps...and 1.8t is practically drop in and what is the fun in that?!  VWVortex is the place to look at such things. 2.0 16v turbo'd passat... www.edition38.com/forums/index.php?&showtopic=34937&st=60 (I don't know if you are a member but it may be worth signing up and using the search or to see the pics in the link - just be aware that you will probably have to sift through a load of 'do you think my wheels look good' type curse word). There are a few places in the 'states that do spacer head gaskets for compression drop. I'd avoid G60's TBH as they are getting long in the tooth, the chargers are made of chocolate and need to be babied if they are to last; tuning them is expensive as is the cost of replacing it when it blows a hole in itself - a turbo setup could be done on the cheap. Have you tried asking on the Audi forums? There're a few contemporary thinkers on them (audi sport...? I think). I'll bookmark this - will be interesting to see what unfolds. You need to check out Vortex though - the amount of info on there is staggering. |

Your opinion is invalid, I've seen your wife.

Have you tried asking on the Audi forums? There're a few contemporary thinkers on them (audi sport...? I think). I agree with what you are saying about KR/9a/ABF etc VAG group 16v units being turbo'd for a few years now and there are some units running 700+ and a handful of nearly 1000hp 16vs which have been proven performers. Id recommend having a browse of ClubGTI and specifically the WOLF R project by TOYOTEC - google should turn up his mk2 16VT. Also regarding the G60 - my original comment meant use G60 MANAGEMENT ie just the loom, harness and injection system which can be configured to run a turbo set up by getting either an aftermarket chip like a SNS Stage 5 + Anti Lag Aside from 1 or 2 sensor issues - coolant temp springs to mind being 1 pin on DIGI and 2pin on 16v but a 9a KE-JET one can be used to get around this. |
