Ok so i have a 2003 WRX, stg 2 mods. moving onto stg 3? i think u could call it that. Anyways im putting in a vf39, 565cc injectors and have the up-pipe/downpipe/turboback combo. Will be flashing with the Cobb AP. So i know that people always get the walbro 255lph fp! But i got a free sti fp. So would this sti fp work fine with my setup. Since my car has the vf39 and injectors, would the STI fp be good to run? I think the STI fp is 140lph? Is that enough?

Thanks any help would be fine. If not ill just buy a walbro from speedelement!

 

get the walbro and call it a day. only 95-100 bucks brand new

 

isnt the sti fuel pump the same as the wrx pumps? do what cornfed said and just get a walbro, its easy, cheap and you won't have to worry about anything until like 500awhp.

 

yup thats what i figured. walbro here i come!
