Time for power mods! I'm looking for....

-VF43
-STi top mount I/C
-Walbro 255 Fuel Pump

do I even need to upgrade my injectors? I have a 07 WRX. If so, I need larger fuel injectors as well.

Thanks BAIC

 

I just sold that same setup about 2 months ago... Hope you find what ur looking for. Bump

 

PM'd you

 

hey wuts the different between vf39 and vf43 and do u change 04 sti injectors if u go vf43 thanks(i knw its a newbie question cuz i am)

 

PMs returned. anyone know if I need to change my injectors with this setup?

 

your stockers will be fine.

 

I believe they are pretty similar turbos. They are both to prone to cracking on the WG but there is less chance with the 43. I saw a comparison and they said the 39 looks to be a little bigger than the 43.

 

stock injectors will work fine but depending on what mods you do next, you will need to upgrade them so they dont run at 100%.

you can be proactive and do them now if you know in the future you will be doing a bigger setup.

but again the stockers will be sufficient for what you are looking to do

sweet, thanks noah and AL. what size injectors should I be looking for?

 

565's should be good shouldn't they? OH man your actually gonna do it ! AWWWW man bump for a good guy ! someone hook him up

 

depends on what you plan on next, if you even do?

we sell deatschwerks, so depending on the setup... 650/740cc+ (ask the tuner what he/she prefers)

well, I plan on sticking with the vf43 for a good while. IF I decided to step it up, MAYBE 18g. well, guess im trying to ask this..

lets say I get the vf43 and upgraded larger injectors, but never end up getting a 18g...will that affect anything?

 

k thanks al

 

for his current projected setup, yes stock will work fine...it's not necessary to change at this time

-Noah

 

then it will be tuner dependant if they would want them upgraded to larger.

stick w/ stock for now....they'll be more than fine w/ the setup
