I'm looking to upgrade my secondaries to 1300cc. I'm also going to install my Warlboro HP fuel pump at this time. Will I need to upgrade the fuel pressure regulator at this time? I'm only running the stock turbos.

 

You should be ok with the stock fuel pressure regulator. But I would recommend upgrading it eventually, especially if you go single turbo. You'll definatly have enough fuel.

 

I might consider it anyway. You can't expect these parts to last forever and you do have a car that is 8 years old.

 

do i have enough mods to add a fuel system (13000 sec, fuel regulator, fuel pump):

mods:
midpipe
apext gt exhaust
dp
apex pfc
new vac lines
ngk plugs (9)

i have the stock intercooler, intake and radiator because i want to go single with the apex rx6 but don't want to buy the gt fmic with dual intaakes because jan or feb i'll be single (run on sentence).

am i doing good or am i in danger?

Usually doing fuel mods before is the best idea! So yes, with your mods up the fuel system. I guess the question should be, "should I upgrade the fuel and ignition system NOW because of the mods I am PLANNING?"

 

I am doing the exact same upgrade--1300cc secondary injectors and Walbro fuel pump.

I am not planning on upgrading the fuel lines or the FPR...I am not planning on running that much more boost...and I feel the stock lines and FPR will be fine with the 1300s and Walbro fuel pump.

Anybody got some leads for where I can get some 1300cc injectors? I'd like to keep my stock 850s if possible.

Also, if anyone has info on removing/installing the secondary injectors and/or doing the fuel pump install...that would be very helpful. :)
