Has anyone done E85 conversion to a Cosworth? Does fuel lines need changing etc. for E85 as it's basically alcohol and it should corrode stuff easier than basic pump gas. On top off that, car might need bigger injectors as it requires around 30% more E85 than pump gas to achieve right mixture. Atleast the performance gain should be pretty good, biofuel Saab's usually make 20-30 hp and 30-40 nm more with E85 than on normal gas.
