If your going to retard timing , why bother running e85 in the first place?
if your going to do those mods and you dont have the money to do it right just wait, i would go with a return style if i was going to spray nitrous and run e85. ZZP one is good its just a eye shore so and ottp one is all steel braided lines and the works so its up to you.

 

So both of them can work. What I am thinking is that I still need a 3" intake and the headers. Those can come later but I got to spend the money wisely, if not I take a year finishing lol.

 

please open up the exhaust first. your pushing soo much air. i made good power with a 2.5 but it was killing my top end
