I have no memory of doing this with my swap. It could be faulty memory, of course - bc it has been a lot of years! Perhaps it was as easy as pressing an 850 style bushing into the crank wihtout redrilling it? I could just be forgetting this step.
Chris Obert was a great help in sourcing parts (and knowing what I needed).
Reading Greg Schmidt's Fiat & Abarth Tricks was helpful as well.
I remember using parts from both distributors to build One that turned the proper direction and was electronic.
The A112 distributor that came on my A112 engine uses the same electronic pick up, module and distributor cap as a 2litre Fiat Spider 2000 w electronic igntion
The advance unit appears the same as the stock 850 distributor, but is marked 16 degrees instead of 14degrees.
I used a PBS water pump and some custom plumbing, and got rid of the monstrous 850 style pump. I converted to an electric fan. People told me I would overheat with the extra horsepower from the 1000cc engine. I thought they were crazy. They were right. I added a small auxilliary radiator under the car and now it often runs too cool in the cold of winter to properly toast my feet.
Block off the mechanical fuel pump and convert to electric - then you can run the fuel line further from the exhaust system.
For a cam, I bought a Delta cam that they called a "split timing cam." Part number DEL 622 sp hp. It has a nice lope at idle and was easy to set up.
I installed a 28/30 DGV using an NOS Alquati intake I found somewhere. My old notes say that another carb option was "Pierce sells 32DCOF2 - side draft small version of 40dcoe"
The A112 alternator worked without modification, BUT you have to figure out the wiring if your Moretti came with a external voltage regulator. J
udge Parker has an 850 Sedan racecar with twin side drafts and a styling little Denso alternator which I want! (see attached photo - NOT MY CAR!).
