What are your power goals? Bare minimum you will need to get ethanol rated injectors, fuel pump, fuel rails, and a fuel pressure regulator and a pro tune.

With this I'd also recommend a flex fuel kit because rarely pump e85 is actually e85
Cobb discontinued their flex fuel kit last I checked. Only real perk of the flex fuel kit is being able to run e85 or pump 93, or any mixture of the two on one tune.

Now things are back to old school, you need a separate tune for pump gas and one for e85. With the e85, tuners typically just have the customer fill up on whatever e85 pump they typically use and adjust the fuel tables to that ethanol content.
