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?

Yeah the stock injectors run out of fuel right around 350whp, for FI e85 I would say to go with a stealth or aem e85 pump minimum if you plan to be over 500hp the 255 in all the FI kits will be running hard on alcohol at that point.

Agreed, a big pump is a must for a boosted e85 370z. I was only thinking of all-motor use when I said I think a stock pump would be good-to-go for E85.
