Rb25det with stock 240 fuel PUMP

[skyview]

Hey whats up guys,
my walbro pump crapped out on me after driving with it for about 3 days so i just through my stock pump back in. Sounds and runs fine.

So my question is, will this pump push enough fuel to supply the stock rb25?
By the way.. my motor is stock besides manifold/stock Throttle body

thank you

[eh?]

I don't have first hand knowledge but I know others have done fine with the stock fuel pump with a stock rb25. Just don't push it.

Okay, yeah im still breaking things in. It's not backfiring or acting strange so good enough for me.
thanks for answer

Do you have an AFR gauge? You will be able to see your afr's leaning out if the fuel pump doesn't flow enough..

na thats the next thing im getting.. but im just being realistic about it. It's not hesitating or backfiring. plus the car was running rich anyways with the walbro.

How come everyone says to get walbro? i think the car is actually running better with a low flow pump

To tell you the truth i think the stock one is doing its job but it aint doing it right, just get another walbro and return that one.

Yeah that's what i thought, because everyone says they have to upgrade their fuel intake. Makes sense.. switching from a 4 cylinder non turbo'd vehicle to a six turbo.

but than everyone says that they run way rich, (i agree) and the answer to the problem is buy an adjustable Fuel pressure Regulator(FPR).

So isn't buying a FPR then turning the flow down just making the high flow pump work harder for nothing?


I dont know if that made sense to you but let me know
