quick question on my vf 39 build
I have a 04 sti
flashed with cobs stage 2 map
cobb catted down pipe
gready ti c cat back
cobb intake heat box is coming
turbo xs top mount
now in the future i wana put a 20 g on but for now i plan on getting my tune with these parts on it that i have waiting to be installed for my tune
port and polish and heat warped exhaust manifold
255 lph fuel pump
prodrive boost Solenoid
gimmick turbo inlet
then my tune
Now my question is.
are bigger fuel injectors such as 850cc really worth the extra 500 bucks for my vf39 or should i hold out on them until i put the 20g on as well?
hold out on the injectors?
or get some and put them on before my tune?

wait for 20g. You will have to tune after the new turbo anyways.

I think both of teh replies above are incorrect.
I say the only way to know if your injectors will be sufficient is the day you get tuned and log idc's you will discover in short order if your injectors are up to the task.
I have a 39 on my car right now and at peak load I hit 90% idc.
That is on a conservative 10.5:1 AFR at the same load however.
