Hello i am planning to make an e85 switch for first mod on my 2005 evo 8, because i can switch back and forth between 91 and e85. I have a stock evo and am wondering what should i get before the upgrade to 85 and if possible could i keep my stock ecu and still be able to run it? thank you.

 

Need injectors, different boost controller, and a tune. ECU stays in the car.

 

Stock ECU yes, Injectors, fuel pump, boost control, tune. But all supporting mods will help with POWER

 

yes you can. just get a E85 pro tune.

 

Also interested in doing this on my x, just unable to decide on injectors and pump. Already found a reputable tuner

 

Your tuner will tell you what works best for your goals.

 

Minimum 1000cc for e85
