Hi!


As promised some pictures of the differences of a std 903 cc head and the 1050 cc Abarth head:




1050 Abarth head on top vs. 903 head on bottom. Only notable differences:
1)The Abarth has opened up the combustion ch. around inlet valve for deschrouding,
2)The Abarth combustion chamber wall (on the spark plug side) are rounded towards the cc. roof, where the 903 has a more edgy transition towards the cc. roof.

Another of 903




Abarth head in its original form - now also with rust and spiderweb included....:-)


In other words: Head design equal in dimensions except for combustion chamber. Valves - inserts - port dimensions are all the same at least on these two a112 heads - I cannot speak for other models like 127/uno etc, but would be surprised if they differ significantly.

Thank you very much , your advice is great sir , it is pretty hard with the parts here in Romania , now depending on the money me and my dad will make a choice , stronger stock engine is better because of the lack of parts so we will see .

Good day to you all Alex P.

Hi Alex!!


Beautiful car!!

I would love to have one of these myself.....

What are the progress on Your engine?

Reason I am asking is that I just visited a friend today. He is racing a 600 in the norwegian historic racing series. He won his class in 2009 (against 1300 minicoopers among others) with a well built modified 1050 engine from an Autobianchi...
these engines are antiques but have a good potential for tuning - cheap parts, and are very easy to work on.

Good luck anyway!!


Best regards

Thank you Remi , thank you Guy , im glad to see you like it and it means alot to me , here not all the people agree with my ideas for the body , i have decided what engine to use , a 1.6 sohc , i hope that not later than this summer to mount the engine on the little 600 , it needs rebuilding but at least i can take measurements on the body for adapting it .
