Brazil has high ethanol % fuel, so any car that is also sold in Brazil is likely to use the same globally homologated components in the US market or whatever your market is. But there are no guarantees.
Basically the 1st generation of people to convert their cars to E85 were very bold and stepped into unknown territory. Now everyone just reads online and looks back and finds out if anyone has converted their particular car to E85 and find out what problems they ran into.
