1.3 specs

I am hoping I don't need them any time soon, but does someone have the engine specs for the 1.3? The manual has all the dimensions for the 1.1, but I am sure the 1.3 differs in at least the bore if not the stroke and crank journal sizes. I asked my local engine machine shop if they had the specs if I brought them my block and crank, but they do not.
I have started considering building another 1.3 as a spare, but so far I have only seen one 1.1 block in a junkyard. If I do build one, I may look at camming it up a little bit or whatever you folks do to get a little more power. I'll have to check the tuning forum for that . I may add a header and a 34/34 DMTR if I build.
Does anyone know if the models you have over there are supplied with a catalytic converter? If not, mine is coming out.

Neznam cemu pisanje na stranom jeziku i sta u stvari tebe muci sem glupiranja na forumu?

Ne znam cemu takav odgovor, ni tebi na tvoja pitanja nije niko tako odgovarao..
Covek je iz amerike, nije nikakvo glupiranje u pitanju.






I hope this is what you are looking for. That is the only manual with some data that I could find in English language.

Pogledao sam ali nisam nasao podatak iz kog je mesta pa je zato u svom pisanju mogao da naglasi gde zivi. Cudno je da mu trebaju ti podaci i neznam kako misli da nabavlja delove?

Covek ne zna srpski,ima nas par sto zba engleski pa mu pomogne koliko moze..google kad prevede ispadne kao da ima neki drugi problem ili kao vec bog zna sta..poceo je covek da prevodi sa google,pola srpski post pola engleski,al niko to na srpskom ne razume 😅

1.3 has 86.4mm pistons,9.2 cr and 240deg 9.2mm lift..if you are building new motor,builld it with cr at least 10to1,i on mine are runing 10.3to1,biger valves and ported,wake up motor just fine..some 1.3 come from factory with 272-9.8mm cam and have 73hp,but with carb you got it would do beter than dat..

Hey thanks, dimmu. That pretty well answers for anything the machine shop might need to know. I'll print those off and stick them in my clipboard. It looks like the crank journals are the same, and the block is the same, the bore is just different. I wonder if I can bore an 1100 block out that far, or if the casting isn't as heavy. Sometimes 'same' blocks can have cylinder walls that won't take much boring out.

  I'm sorry if I seem like a jerk posting in English all the time. I am working on learning Russian right now which has helped me identify at least a few words on here. I don't know Serbian yet, and Google translate seems to provide a somewhat mangled product at times. It's especially bad with technical language. There have been a few posts on here I have translated that way, and still have been unable to piece together. I can only hope Google translates my posts in a more comprehensible fashion.

  I actually just started adding Google translate output to my posts a few days ago. I am here to make friends, not enemies. I surely don't want to make anyone angry at me. I've basically found one English Yugo resource, and it's a mailing list that's mostly dead. I am an American, and I understand we don't have the best reputation overseas. I was made to understand a lot of people in Serbia can speak English. Right now your choices from me include English, passable Spanish, less German, or bad Japanese.  I've got to say, your language is a little difficult to figure out. You've got five consonants that all go 'ch' a different way in the Roman alphabet, and ican't quite distinguish between them, plus you have several characters in your Cyrillic alphabet I don't have figured out either. But, I'm trying.

As to actually doing the engine, the boys at Wood's have been at it a long time. They're a good shop, and we have taken them harder jobs. They even do rebabbitting. I also have ebay, and a guy in Texas who does Yugo parts. Worst case scenario, I can have a set of pistons or rods made. We have a lot of custom engine component manufacturers in the USA.  I may yet even order some parts from Serbia. I would very much like to have a set of those metal door handles, and a tray to replace the one I am missing.

Anyway, I apologize to you zmaj87 if I have been impolite or if I seem stupid. It seems pretty logical to me to look for knowledge from the place the car comes from, and where they are used more regularly. As per my new procedure, I am including a translation of unknown quality.

Update: sounds like applying a translation isn't doing a lot of good... I know I keep using translation in my browser, and get some very interesting results. There is one thread where the translation makes no sense. It sounds like the ravings of a crazy man. If that's how I sound in Serbian via Translate, I'll quit doing it.

Junior45: 10:1 is awfully stiff. I'd absolutely have to run high test fuel. Sounds like I do have an option to cam it up a little, but I may have to know more about the cam. I don't think it's one I can just buy from Summit. I do know my 1.3 seems pretty strong, and I am considering a 32/34 or 34/34 DMTR and an MSD ignition. I may already have the big cam. I'd also like a header, but I don't know if one exists, and I need to know if I can ditch the catalytic converter.

Hej hvala, dimmu. To prilično dobro odgovara za bilo šta što bi prodavnica mašina mogla znati. Ja ću ih odštampati i držati ih u memoriji. Izgleda da su časopisi čudovišta isti, a blok je isti, izvrtanje je samo drugačije. Pitam se da li mogu da izvučem 1100 blokova toliko daleko, ili ako lijevanje nije tako teško. Ponekad "isti" blokovi mogu imati zidove cilindra koji neće uzimati mnogo dosadnijih.
Žao mi je ako izgledam kao kretanje na engleskom stalno. Radim na tome da naučim ruski jezik koji mi je pomogao da identifikujem barem nekoliko reči ovde. Još uvek ne znam srpski jezik, a Google translate izgleda ponekad obezbeđuje donekle iskrivljeni proizvod. Posebno je loše sa tehničkim jezikom. Postojao je nekoliko postova ovako prevedeno na taj način i još uvek nisam mogao da pišem zajedno. Mogu samo da se nadam da Google prevodi moje postove na razumljiviji način.
Upravo sam zapravo počela da dodam Google translate izlaz na moje postove pre nekoliko dana. Ja sam ovde da se družim, a ne neprijateljima. Sigurno ne želim da me neko ljuti na mene. U suštini sam pronašao jedan engleski Iugo resurs, i to je mailing lista koja je uglavnom mrtva. Ja sam Amerikanac, i shvatam da nemamo najbolju reputaciju u inostranstvu. Napravljen sam da shvatim da mnogi ljudi u Srbiji mogu da govore engleski. Sada vaš izbor od mene uključuje engleski, prolazni španski, manje njemački ili loši japanski. Moram reći, vaš jezik je malo teško shvatiti. Imate pet saglasnika da svi idu na drugačiji način u rimskoj abecedi, iako ne razlikuje između njih, plus imate nekoliko karaktera u vašoj ćiriličnoj pismu i nisam shvatio. Ali, pokušavam.
Što se u stvari radi na motoru, dečaci u Vudu su dugo bili u tome. Oni su dobra prodavnica, a mi smo ih uzeo sve teže poslove. Čak i rebukuju. Imam i ebai i momak u Teksasu koji deli Iugo. Najgori mogući scenario, mogu imati set klipova ili šipki napravljenih. U SAD-u imamo puno proizvođača proizvođača motora. Mogu čak i naručiti neke delove iz Srbije. Mnogo bih voleo da imam skup metalnih ručica za vrata i tanjir za zamjenu onog koji mi nedostaje.
U svakom slučaju, izvinjavam se vama zmaj87 ako sam bio neumoran ili ako izgledam glupo. Čini mi se prilično logičnim da potražim znanje iz mesta na kojem dolazi automobil, i gde se redovno koriste. Prema mojoj novoj proceduri, uključujem prevod nepoznatog kvaliteta.

Čovek je u svojoj prvoj poruci na forumu napisao da živi u Ajdahu, i nema ničeg lošeg u tome što sređuje svoj auto i što traži pomoć na forumu. Na kraju krajeva svi mi ovde tražimo pomoć, i to je pored druženja glavna svrha bilo kog foruma, ne samo ovog...

Mine is 10.3to1 and i run regular 95 petrol..i have efi and dont have cat,no yugo with carb here had cat

Welp. Looks like the cat is coming off too.

Strait pipe like mine was 😅

No problem. You can download that manual from this link: https://www.scribd.com/doc/272070945/Haynes-Yugo-pdf
As for apologizing, there is no need for that.
That is just a Serbian mentality at it's best, some people react like that but later on they will be ok with writing in English. Well, maybe not everyone :cough: ZAC :cough:
We've already talked about how google translate messes up words, so as long as you open topic's in right places it is all good
Whatever parts you need I don't think it will be problem to ship them to USA. I can't really say how much it will cost but it all depends how big the package is.

I'm actually looking at ordering a part from Slovenia right now... There's a set of rear window louvers for $80 and $40 to ship. I'm going to see if they can find a tray and fit it in with the louvers. I'll have to find the topic I was looking at... One of them translates so badly I can't even puzzle out what kind of repair they're talking about.
As to the manual, I am on a phone and it won't let me just download the pdf. Right now I am stuck with using the Scribd app. They also have the manual for my baler that I'd like to have as a pdf so I can just print it off. Scribd has been a thorn in my side for a while.
Contrary to popular belief, all of America isn't a rich wonderland of people who live like it's an episode of Beverly Hills 90210. My sole connection to the Internet is on a cellphone.
Any word on who the resident electrical genius is? I have a post on Instalacjie related to my other big problem. I got my paint worked over last night, my new control arm is on its way, one tire and low beams and I'll be ready for a run to Boise.

Well that is a total rip off if we are talking about Yugo rear window louver.
People are selling it here for 22$

Someone will probably answer you that question about low beams, but try to be patient.
August is a month that most people from Serbia use for vacations and forum is not that much active as it is usually.

The irony is that it says it was made in the USA.

It can be bought here in Serbia to.. it was very rare part here, but there were some parts, that were shipped from USA back to Serbia, so it can be found here too every now and then. As for the electrical problem, try to change the switch or wait for Miljan, he might help you.

If I can find out which pins are supposed to do what, I can test the switch. I did end up probing power and ground to the connector, but never did turn the low beams on that way. I did turn on the high beams.

A bit tardy, but you cannot overbore 1.1 to 1.3.

Greetings from NC!

That is good to know.

Does the head for the 1.1 differ from the 1.3 as well?

Same head,just a litle smaller head chambers

So I could conceivably raise my compression ratio that way?

No, difference is not very big, you'll get maybe max 9.7:1 from factory 9.1:1...

That puts me closer to 10:1... I'm not sure what else you are doing to raise compression on these... Aggressive decking would not be good since it would alter the timing belt length.

We angle-mill the cylinder head for 10-10.5:1 and timing belt is not a problem. But you likely need to put a adjustable pulley for camshaft if you want all to be perfect.

I can get a head built here, I just need to know the best practices. I went over the valves yesterday. The clearances are all acceptable or correct, so now I am looking for the cause of my click again.
I also installed a thermostat. Previous owner had done some stupid stuff, including removing the thermostat. They broke one of the bolts. I broke the other two. I got two out and drilled out the third. I scraped out some kind of calcified junk that may have been stop leak. Either way, it's nice to have heat while moving.
I did find another GVX, but it's in Kentucky. Still on the search for a spare. I'm more worried about my gearbox... It's rather noisy. More parts coming next week. I'll have it all sorted out soon. The next big pushes are electrics; both washer pumps and the heated window.
