So Im going to be buying an rx7 to start my project on and I'm going to be going with e85 I know I need bigger injectors for the 30% more fuel, my question is dose anyone have suggestions about this or has run e85 and could tell me some of there results

 

I heard running E85 is unstable not sure reason for it. Also much more cheaper on gas!

 

Hm.I've been looking I to it and haven't seen to much of bad news but I will have to post in a different section on here to see if I can get some responces, I mean if you can run it you can make a lot more power without detonation it has a lot of plusses to it and it runs super clean

 

Hey man, I see you're in Arizona, I'm located down in Gilbert.

Don't listen to that other guy, E85 is a great option for an FD.

It depends on what kind of power you're shooting for and what turbo setup you have, then you can pick injectors accordingly. Injector Dynamics is a local company here and have good options for E85, also Full Function Engineering is local as well and they make the fuel rails you will need to run bigger injectors. I would also suggest picking up an Adaptronic plug and play ECU so that you can run a flex fuel sensor so that you'll still be able to switch between E85 and pump gas easily.

You're also in luck because UMS Tuning in Mesa can tune FD's and they are a dealer for Adaptronic and Injector Dynamics, and can also do installs for fuel system stuff as well. Talk to James, their number is on their website, UMS Tuning :: Home


There is a whole section dedicated to alternative fuels, start browsing through it and you will learn more about E85 use in rotary applications. https://www.rx7club.com/alternative-fuels-249/

 

around here the only drawback is availability of that fuel.

 

Flex fuel capable ECU takes care of that, just won't be as fast when you have mostly pump gas in the tank.
