In the next year I am planning to swap to e-85, Fp-black, and Manley rods and AMS pistons.

I currently have... ARP head studs, springs and retainers, S1 cams, 255 walbro

Will the fuel pump be big enough for say 500 ponies?
What size injectors would be best(links to exact injectors you would prefer would be great too), and possible running two tunes? One for e-85 one 93oct...

I definitely need to upgrade my fmic..

Thanks for any replies.

This being what I was looking at...

 

you could run another 255 in line for e85. as far as the injectors i'd suggest id2000s/fic2150. spend the money once and never have to repurchase. They also have phenomenal idle control, much better than the low Z 1250/1450/1650s etc

EDIT***
I would also recommend having two maps so that you can run a few tanks of 91/93 through it every 3-6 months to keep the e85 from gunking up your motor/injectors.

 

So one 255 won't be enough. And I won't be buying injectors twice. The setup I posted. Looking for 500awhp is my stopping point. I am sure everyone says it. But this is the truth

 

Doubt it. E85 requires 30% more fuel for the same power as pump gas. Someone else may want to chime in on injectors, although the search function will do you wonders. You know my suggestion.

EDIT***
And as an FYI the FIC2150s are about 250$ more than what you are going to need for a low Z injector. Well worth it IMO

 

Go with the double pumper from buschur...quick easy and never have to worry about it again. I know they push 700hp with their double pumper
