I have the following for my fuel system, but I'm not sure if it's enough to run E85.
DW300 fuel pump
FIC 900 (1000cc) injectors

Should I get a rail and FPR, and maybe larger injectors? Do I need to upgrade the stock lines?

 

how much power are u trying to make?

 

I want to make 550-600 on E85. If I make over 500 I'll be happy.

 

my guess is u could make around 550 on e85 before u max out ur injectors or ur fuel pump

 

You are going to need bigger injectors if you do not raise your base fuel pressure. I started to run out of fuel with one aeromotive pump on 1600 ID's at 544whp at 18psi E85. You can get close to 500whp on your current setup. You dont need a rail and your stock lines are fine for that power level.

 

Can you put a FPR on the stock rail? Looks line I'm gonna need bigger injectors at the least.

 

You can use the aem fpr w stock rail.
