Apologies if this is not the appropriate thread, chose it because the 127 also used the Fiat 100 Series engine along with the Autobianchi A112 and other models.
Anyway the Fiat 100 Series engine has fascinated me being a compact engine with a long production run, interested to know more about it particularly whether any experimental updates and unbuilt developments were considered for the engine over the years before it was eventually phased out in favour of the FIRE units in the mid-1980s?
Was the 1050cc version used in the A112 Abarth the absolute limit the engine capable of growing to in terms of displacement or was there still more scope for further enlargement (potentially overlapping with the Fiat 128 SOHC engine)?
