Guys, I have been looking for a while into these cams and I am at this stage not sure whether I can get hold of brand new OEM FIAT parts. However, there's a chance you can get these cams as replacement parts from AJUSA (I haven't checked with them personally).
Part number for Tipo cam from AJUSA is 93077900.
Part number for Coupe 16VT cam from AJUSA is 93044300 and CAMPRO is CP16468.
Plus if someone's quick there's Tipo inlet cam by AJUSA for sale on ebay.de -
390521951060 I might be able to help anyone looking to buy these as it seems they're available in Poland (at least from what it says on the www - still awaiting reply from retailers).
Cheers,
Jack
