I did a search and didnt quite find the answers i was looking for. A rough breakdown of my set up is the following:

t04e ball bearing
fully rebuilt block+internals
full head work
-8an feed, -6an return steel braided lines
walbro 255 intank fuel pump
paxton fuel filter
paxton fuel pressure regulator
rc 720cc injectors
AEM fuel rail

My question is, at idle what should i set my fuel pressure to be? I saw on some threads they recommend 40-47with hose on and like 37-41 with hose on, but i just wanted to ask you guys just to be on the safe side. Also, this will be the settings i need BEFORE i put my hondata 4b on, will i need to change the pressure once i have the 4b installed? I am going to have it dyno tuned 3 weeks after i get the 4b on, i just need it in good driving condition until i do so. Thanks guys

How do you plan to even use those injectors before you get the Hondata installed? They are like 2.5 times larger than stock. I don't think your ECU will be too happy without some kind of fuel controller.

Yeah, you wont be able to idle those things w/o the hondata.

To answer the question, considering the hondata is installed. You would want 50 psi atmospheric. Ofcourse you will have to tell the hondata this when you burn the chip.

 

i forgot to mention that im running the stock 240cc injectors untill i have the hondata installed....
