fuel injetors question
ok i have a few question about the stock injectors because im been searching around and it seems that the stock injectors can support for alot, but im confused about it. how much does PSI the stock injectors really support with the stock twins? plus should i upgrade with 850/1300 to be safe? plus my other question is, is there any bigger intank pump other that the walbro 255? thanks

The stock injectors on an FD can support a lot:

You could easily have found that one with a search, though.

rule of thumb is 12psi.... but 12psi on OEM Turbos.
clearing up WHAT TURBO you are planning on running would help answer you question a little better (looks like you are asking for stock twins??). 12psi on your OEM twins is not the same as 12psi on a large single. This is why you see the answer represented in HP, not boost. CFM of a turbo changes from one to another.

i never thought about how much in HP that injector can handle. because i use to have my turbo II setup and i actually running 550 pri and 800 sec with the stock turbo at 15psi and street ported and it seems not enought with what i had. of course ecu settings and fuel pressure will play a role on it, but that why if i want to have more boost or a boost spike, wich all turbo rx7s have that, the stock injetors will handle it. you can tell me that it will handle this much power, but in reallity not all injectors will handle the same. some more, some less. and yes im asking for a stock twin turbo setup. im just worry that from idle to the 3800 rpm will lean out. but with the power FC, is this gonna be enought?
