how much hp does the stock gsr fuel pump hold?
okay first thing i dont know much about fuel stuff yet so i dont even know if this question is a good question....does the fuel pump flow even compare to hp or no?...my situation is that im kinda low on money to finish my setup and i was wondering if i could put the walbro255 on hold...the setup is just stock gsr, using t3/t04 54 trim turbo, boosting 7-9lbs, rc 550cc, going to be tuned on crome...so is the fuel pump a must rite now or can i put it on hold when i have more money?...i already know its probably recommended and good insurance or whatever, but how bad will it be without one?

As long as you have an adjustable fuel pressure regulator you wont.. Just check the pressure with the stock fuel pump and make the pressure the same with the new fuel pump..

on that turbo and running that boost pressure you will be running close to if not more then 250whp so I would get a pump. Worse comes to worse though you'll lean out in high RPMs and blow up...no big deal though 
. I would say get a 190lph pump, but the 255 is the same price pretty much. I wouldn't risk stressing the stock pump. It's kind of like injectors, you can do 100% duty cycle, but I wouldn't risk it
