Just thought I'd resurrect this subject with the latest position...
As the forum knows this is indeed mine and driven home from Switzerland in July. It's a nice original late example but needs a lot of work to have it like I want. It's currently undergoing a lot of mechanical changes - Mostly component replacements in order to make it a reliable and comfortable companion on long 3MA trips - There are two especially long dstance ones coming up in the next two years.
Anyway, back to the engine the emissions stuff is now all gone although it wasn't possible to fit a more conventional exhaust manifold. I forget the reason why....Anyway this is what the engine currently looks like and sporting it's shiny new radiator from Yagmur.
A small bit of extra information that I think is fairly correct came to light last night and prompted me to update this thread. Another Swiss S3 2.0 has appeared for sale (details posted in the For Sale section) and it appears to have a similar system fitted. According to the Italian 131 site this was standard for the Swiss market...so maybe there is no US spec connection at all for my car..? I think Alf mentioned earlier that the Swedish BHP was 110 (down from 113). This seems to link in with the fact that the Ritmo Abarth 130TC was actually called a 125TC in Switz alone...maybe because of additional emmissions equipment on that model too.
