Then I wont try it with them! I will make sure I have enough injector before I try.

No way would those work..unless your going for 4xx.

Buy my injectors...$350 Need to be flow matched though.

E85 can be as much as 100hp over 93 Oct but as said before you need the fuel for it
I would say right fuel system , e85 and a little more boost 500+ can be had even on the stillen kit

I have the CJM road race fuel pump with the S1 fuel system on order so the fuel system is covered. When Stillens kit is ready I will add more boost and injectors and we will see if your right! Hopefully there is a good upgrade for the 7AT by then because I will probably need one if you are right!

Do you know what degree your timing currently is?

No I'm not sure what it is right now.

When I converted to e85 I went with larger injectors, AAM return loop fueling system, adjustable fuel pressure regulator , all stainless.braided fuel lines and fuel cell and pumps designed for e85. Don't underestimate the corrosive nature of e85. I don't think much of OEM fueling system is up to rigors of pumping e85.

My car now makes well over 400 wHP in naturally aspirated form running pump e85.

Not only do you want larger injectors but ones rated to run e85. I used 725cc on my NA motor.

Everything in the 370z fuel system is fine with E85.

For any boosted 370z on e85: 1000cc injectors!

have you tested this? The pump injectors and line are all fine? So all you would have to do is tune for e85 then? Oh and find as station to get it at?

No, he means that all the lines and such are compatible with E85. You still need injectors and pump.

Ah and tune of course. Is this even "worth" it WHP on a bolted car or just for FI. Thanx

I don't think you would need to upgrade the fuel pump. But you're right my point is that there is no problem with e85 compatibility. As for if your fuel system provides enough volume for it is another issue.

Edit nevermind I was thinking the stock injectors were 440cc but I believe they are actually like 310cc so injectors would be pretty much for certain, sorry.

Plus, as cheap and easy as it is to throw in a Walbro 255 at the bare minimum wouldn't it make sense to give yourself headroom?

All the Fast Intentions data is crammed into one really long thread so I cannot dig it up within the hour lol... but on one of their projects they checked to see if the stock fuel pump was up for a bit of horsepower and it kept up with as far as they bothered to push it before swapping it out precautionary.

I think the stock pump would probably keep up. Its at least something I would do only if it wasnt holding, rather than proactively. That is, on a NA car. A fuel pump is always running at 100% in the Z since there is no resistor pack or anything... so its not any extra wear on the pump to use it for all its got. I just wouldnt want to run it to the max on a boosted application since environmental conditions and boost variances will cause fuel demands to have a bit larger swing.

But there is certainly no harm in upgrading the pump anyway. I think I am going way off topic here mixing up 2 active threads on E85. This one here is supposed to be about a supercharged application I suppose.

Ive been working on converting my car to e85 for a while. Should be able to get it done by next summer. Have a few small issues i ran into on my car since installing my supercharger. But once i fix it i plan on doing e85 my tuner also wants to do this badly. Im going to get a return fuel system and im going to run a dual fuel pump setup. I already have both pumps and i have id1000's in the car already.
