Does anyone know which lines exactly need to be replaced to run E85 on a stock fuel system? I want to run E85 naturally aspired and tune using Uprev Osiris.

The FSM simply says "tube" or "line." Does not say what it's made of.

 

Why? The E85 only benefits (perf-wise) the boosted bubbas...

You need new injectors and pump. Metal lines are fine - only hoses may need to be swapped.

 

Probably because it's cheaper.

 

It can help NA tuning as well... 100 octane helps when you're pushing timing to the limit. The loss in mileage pretty much defeats the cheaper price though.

I'd also be interested to know what has to get replaced for E85. Surprised there's no threads about this.

 

its a big thing on the evo forums

 

My neighbor just changed his 450 hp srt-4 to E85. He told me he added a bosch 044 inline pump and surge tank. Obviously, he also went with bigger injectors. I believe he is still running stock fuel lines for the most part. He has me starting to consider switching my car to E85. I am going to start looking into it.

 

Proedi128 something something they use it on a supra and recently on a 350z . It allows you to use both gas and e85 and the program does all tha stuff. Like you can have a quarter e85 and have 1/2 gas. And you can still run the car:0)

 

dont need to replace anything. stock lines are all coated so they are fine

 

Turns out it is true. Maybe a benefit of Renault and Nissan working together in Brazil?

I ran it for 3 days straight with the only problem being a lean condition on bank 2. Could have been caused my a vacuum leak. Osiris will take care of adding more fuel soon.
Should be a nice power increase running aggressive timing.

The low MPG and low price comes out to about the same as running 93 octane. BUT E85 is US made and makes more power from tuning.

 

Curious to see if any NA Z's have seen results from switching to E85

Might not be much of a "gain" but it's another option.
