Talk:Fiat 124 series engine

Very interesting page but could you prove that the VAZ licensed engines and the Fiat Brazilian engines were derived from the Type 124 OHV family? This is the first time I hear something similar. Scott DNA (talk) 07:13, 17 July 2014 (UTC)


 * The Brazilian engine was absolutely derived from the 124 unit - see the dimensions for instance. The VAZ info was added by some ip a while ago; I removed it until someone can verify/reject it.  Mr.choppers &#124;   ✎  00:54, 18 July 2014 (UTC)


 * Also, how do reckon that the 1367 was derived from the 1929 and not from the 1301? Check the dimensions:

1301cc: bore 76.1 mm, stroke 71.5 mm. 1367cc: bore 78.0 mm, stroke 71.5 mm. 1929cc: bore 82.6 mm, stroke 90.0 mm.


 * I don't have a good source available at the moment, but the shared stroke should be enough to restore the 1367cc diesel to the article. There was a 1698cc derivative of the 1929, maybe that's what you are thinking of? Also, remember that there was a 1367cc petrol version built in Italy, which shares the exact dimensions of the Brazilian-built diesel. Cheers,  Mr.choppers &#124;   ✎  00:59, 18 July 2014 (UTC)


 * I think that sharing bore/stroke dimensions is not a strong connection; many unrelated engines could have common dimensions (ie: Alfa DOHC 2-litres and Fiat DOHC 2-litres, both 84x90). Maybe your assumption is true, but in my opinion we should find something more to prove it.
 * We know that Fiat DOHC, Fiat SOHC (128), Fiat OHV (124) and Fiat Brazil were all designed by Aurelio Lampredi. In a old interview Lampredi said that not even a single bolt is shared between Brazil engines and Type 128 SOHC engines, but I haven't see/read nothing about a connection between Brazil and Type 124.


 * The 1367-1698-1929 diesels seems to be a single family, because some people that disassembles and repairs those engines said they are almost identical at the sight. Someone told me they were built on the old OHV-124 assembly lines, so maybe there's a connection between the two families. But for sure the 1301 diesel was built in Brazil and the 1367-1698-1929 diesel engines were built in Italy.


 * I'm interested in the history of Fiat engines and I'd be very glad to hear your opinions.

 * I do wish that Fiat could have developed a better naming system, as it is currently very hard to tell what was going on with which engine. Does this page give you any useful info? It seems that Fiat renamed engines willy-nillily depending on which car they were fitted to. The 1301 is referred to both as the 127.A5.000 and the 146.B1.000, while the 1367 TD is usually called 146.B3.000.  Mr.choppers &#124;   ✎  00:11, 19 July 2014 (UTC)


 * Wow - just realized that the Campagnola's 2-litre diesel also has a 90mm stroke, although it seems to be based on the 124 original block.  Mr.choppers &#124;   ✎  21:26, 17 August 2014 (UTC)


 * Hello, as a long time owner of several Fiat/Lancia cars and having worked on a lot of these engines in the past, I can say for sure that the Brazilian engine (FIASA) is NOT related at all with the 124 engine. It was a totally different beast, having inlet/exhaust on the front and all the accessories on the rear (the transversal 124 engine was exactly the opposite, much more like the 128), and the accessories themselves were located in different points on the block. Block dimensions were different altogether, with the FIASA engine being smaller and lighter and incapable of going over 1500 cc, and even the bellhousing pattern for the gearbox was totally different. The 1301cc NA diesel was a FIASA. I think that all references to the FIASA engine should be removed from this article and put in a different, dedicated, article.
 * At the same time, I can confirm that the 124-SOHC replaced the old pushrod OHV on the very last series of the 131 of 1982, in 1367cc and 1585cc versions, and lasted only for 2 years (in Italy at least). The diesel 1367/1697/1929 both NA and Turbo are all derived from this late SOHC version: they were in fact the last 124-derived engines still produced in Italy after 1984. The older 1714 NA diesel of the first Ritmo/Regata was NOT really a 124 engine but was loosely derived from the 1756 cc TC of the 132 with new head and pistons (I have an article from the italian magazine "Quattroruote" from 1980 explaining this).


 * Nice, let's do it. Is Fiat FIASA engine a good title? Do you have that 1980 article available? I would love to see a scan or something.  Mr.choppers &#124;   ✎  01:31, 24 May 2019 (UTC)

fiasa doesn't exist
This article was divided, creating a new page for FIASA, an engine that never existed and that is technically just a version of the 124 series. FIASA is just an acronym for Fiat Automóveis SA, the company that did it.
