Is it worth it to go E85 on a turbo build? What parts are needed? Will any old 1000cc injectors work?

 

Depends on power goals. I'm doing a flex fuel setup so I can run 93-E85. E85 will take atleast 30% more flow than regular gas. So bigger injectors are needed if your power goals are high and a big / dual fuel pumps.

 

I'm only looking for 400-500 Whp. Would 1000cc injectors work? Is a special type of fuel pump needed or just one with big enough flow? Will I need to upgrade the fuel rail?

 

They make e85 pumps, I'm going with the walbro 416 e85 pump, and the id1300 injectors due to the fact there stainless. I don't drive my car much and e85 isn't food to let sit. I'm sure the 1000 with net you 400+ I'm going to try and push the id1300 to 600. Stock rail will be fine

 

How long does E85 sit for? Would I have to drain the damn thing every winter?

 

as long as you put a couple of tanks thru before putting it away, they say thats good enough to clean the system before storage (read it here on s2k )thats when a flex fuel system and tune comes in handy
science of speed sell a nifty flex fuel system

 

What all is in their kit? It kinda looks like just injectors, pump, and EMS,

 

The have just a flex fuel sensor kit. You get there mounting kit sensor harness fittings. Everything to install it.
I'm just running a GM sensor and harness and will pick up a gauge to monitor my percentage

 

you should pick up a flex fuel kit. im looking to get one soon from SOS. in my opinion its worth it because from my understanding E85 isnt always the same. even if you plan on running straight E85, the flexfuel kit would still adjust your tune accordingly to the content if for some reason your E85 isnt always consistant. i could be wrong though.

 

I store my car with E85 for 6 months a year without any issue. I also do that on my STi, and did it on my SHO when I had it as well. If the system is sealed, then moisture won't be an issue. Since ethanol absorbs moisture, that's what you have to worry about. I just did a track day on about a half tank of my 7 month old E85. Still smells gud!


As far as E85 being worth it... As long as they make it, I wouldn't run anything else on a boosted car. Even if your power goals aren't crazy, E85 is safer and burns cooler. If it's available near you, there really is no reason not to run it.
