well I want to go E85 for performance so I’m wondering what exactly do I need new injectors? New fuel lines? New fuel pump?Marco:
What are you hoping to accomplish with the change? As Kraut mentions, there are E85 compatible parts that are included into an E85 capable system. The fuel lines and fuel pump are different. The control systems are more complex. They must be able to figure out what percentage of E85 you have added, and make adjustments so the engine will run safely.
E85 can produce as much performance as gasoline, but the mpg is less. You will use more for a given number of miles than you would with gasoline.
