aright im going to be using a hybrid to4e with 57 trim wheel and i also have an FD fuel pump new which i believe flows 243lph.. i have s4 fuel rails and im not exactly sure as to what i need to have done to the secondary rails for the 1600cc injectors and what else i NEED to get as far as lines, fpr, etc. can someone please clue me in to whats necessary to upgrade the fuel system to accomodate these things??? thank you guys

annnybody? is it a different secondary rail for 1600s or does the stock need to be modified?

teknics

you can use 1680s from injector.com (marren fuel injector)



just buy the pro import injectors, they're plug and play with stock rails.



as for an FPR the aeromotive 13109 (i believe is the part number) is the main one most people use it has a rising ratye of 1:1 and bla bla bla its the one to go to.



as for lines you could just use stock rubber hose and get slipfit AN adapter for the FPR so you dont need to swap over to braided lines if you dont want to.

thanks you.. thats what i was lookin for lol.. i think i may run smaller injectors im not sure yet.. like 1300 or so but i may just end up using what you suggested! thanks again



are those 1680s the american or jap o-ring style??

teknics

if you choose the pro-import ones theyre the same style as the stock ones, aka japanese.



they are literally drop-in.

n/p.



i believe theyre low impedance, it says on the site i havent bought them in a while so i dont recall off the top of my head.

i didnt know it made a significant difference whether theyre p/h or saturated but ill just go with the pro import ones on the site

teknics

yea dont worry about the other options, as long as its pro-import its good.



if its low impedance you may need to solder in resistors.



also dont forget injector clips, they sell them with or without wire pigtails.
