VF34: injector size

If im going 2 run a Cobb AP map for a VF34 on my 2004 WRX, will i have to use the Sti pink injectors(which are 565 cc) or can i use another brand/larger injectors. If so id like to run 680 cc injectors, just o be on the safe side for future mods. Also does anyone have an approximate 0-60 mph time and 1/4 mile time for the AP map VF34 setup? Id just like to get an idea of where id be at. Thanks for the help.

if you want to use anybody else's map (cobb's or whoever), you have to have the same exact fuel system. Yes, you should use pinks if the map is made for pinks. No other size will do. If you are going to get it tuned, you can put larger on there sure and then just get it tuned to handle them.

565ccs are enough for a VF34 though, it ain't that big.

You will be fine running an up pipe.Its more for safety sake anyways. Removes the cat and the O2 sensor that are right before the turbo.

no, you want that cat gone if you're running an aftermarket Turbo. You need to switch that out. While you're swapping the turbo is the perfect time since it's much easier to take off if the turbo is out.

scoobymods or whatever has some walkthroughs maybe... any bolt-on turbo write up should work for you. No, I don't have anything offhand.
