I'm curious if anyone is running a stock fuel pump on their set-up. My initial set-up was a TD05-12a boosting 15 psi a few times until i installed an intake and exhaust, this backed it off to 8. At the time, i was simply running an FMU on a completely stock fuel system, the stock fuel pump seemed to supply it fine because it pulled hard, but i've no idea my air:fuel due to not having a wideband.

Now i've upgraded to a T3 Super 60 and DSM 440cc injectors chipped with an Uberdata base rom boosting 10psi. Is anyone running a similar set-up with a stock fuel pump without leaning out?

Edit: I've yet to drive the car with the new set-up. I let someone else do the chipping (i didn't trust my soldering) and i'm still waiting on it, as i wait, i figure if the stock fuel pump won't be sufficient, i can order what i'll need so it will be here when the car is ready to drive.

Everybody is running a stock fuel pump. Upgrading is just for your piece of mind. The stock one is working hard with your setup, but it is working, and that's what counts.

iv'e never really heard of anybody upgrading stock fuel pumps on turbo conversions. it is more common to need to replace the the fuel pump on nissan engines such as RB25DET and RB26DETT which fuel pumps max out easilly.

no one here running walbro, just stock fuel pump?

SpankedYA!

I run a 255 walbro. I installed it for piece of mind because my stock one had like 175k on it. I have the standard not the high pressure.

I run a walbro fuel pump with my setup. I love honda and all but with 440cc injectors and possibility of upping the boost later... why risk it? If you have the money upgrade it otherwise see what happens........................................... ............

if you are going to get one get the standard and no high pressure........I'm still running stock with about 150k :P

you dont reqiuire extra pressure of a walbro, your using the same pressure with a bigger injector, allyour doing is flowing more at the same pressur... ---- it, im keepin the sti\ocker cause it works, never had a problem... if itll take 16 psi with 550s and work mint, good enough for me
