E-85 on a stock 370z?

-On an NA car, you can run GT-R injectors for E85. That's your cheapest immediate option.
-On a boosted car, with 93 octane, you already need substantially larger injectors. I'm running 750cc @ ~500whp, using about 80% of capacity.
-If I were running E85, I'd need to increase size substantially, probably 1300s or 1700s.
-If that's where you're heading, you'll also need a bigger fuel pump or fuel pumps to provide appropriate flow.

You'll absolutely need a tune once you go to larger injectors. Trust me when I say that your car will not work with incorrect fuel scaling

Edit: +1 on Rusty's comment about the AAM twin turbo kit. Do not go for that one. If you want twins, go Fast Intentions. If you'd consider a large twin scroll turbo, go BP.
