Default Fuel system for current and future goals with E85?

I am thinking of switching to E85 on the Procharged WS6 in my signature which is currently making 556 rwhp 485 rwtq. I know that I will need larger injectors to make the switch and possibly a BRFPR but I don't know if I will need to upgrade my current fuel pumps or upgrade the stock lines. I don't want to buy injectors twice or anything else for that matter...

Eventually, I will build the bottom end and max out the D1SC or go with a F1A, so anywhere between 700-900 rwhp. At this point, I know that the rest of the fuel system will need to be upgraded.

So I guess my questions are...

1. What injectors should I purchase that will work with my current setup but are large enough to work with my future rwhp goals and E85?

2. Will the dual Walbros be enough fuel pump for my current setup with E85?

3. Do I need a BRFPR to make the switch to E85 with my current setup?

4. Do I need to upgrade the stock fuel lines to switch to E85 with my current setup?

I'm just re-saying what i've seen people run, so take it for what it's worth...

-12 feed to the filter/magnafuel 4303. -10 to a Y to the rails. -8 from the rails to whatever regulator you want to run. -8 return.

120 lbs injectors.

That should be good for just about anything you can throw at it lol

Thanks for the reply and good info but I was looking for what I need to do to run E85 as my car is currently setup but will also work when I build the engine down the road. So if 120 lb injectors will work for my max goals, could I just upgrade the injectors now and retune to run what I have in my signature? Or do I need to upgrade anything else? Regulator, fuel pump, lines, etc...

I have dual walbro pumps, -8 braided steel feed, BRFPR, 95lb injectors, speed inc fuel rails, racetronix hotwire, and pushing about 17psi. So far so good, but having some issues with fuel pressure that I'm testing for today. Might be my injectors or pumps

You have quite a few options depending on the vehicle usage.

Feel free to give me a call if you want to discuss in more detail.
