sr20det fuel pump walbro 225 lph

[phantomfoot]

Is the walbro 225 lph will be enough for Sr20det swap?

I just did my Sr swap and i put this walbro 225(I useless see people use walbro 255 lph) in my car.Every time i rev up to 5000 rpm the fuel cut, so i don't know if the 225 one pump enough fuel for Sr20.

Plz help, This is suck when u can't rev up above 5000 rpm.

That isn't your problem....even at full throttle, a stock SR will not even use 1/2 the flow capacity of a 255 lph Walbro pump.

So if yours is 225 lph, that's not much less.....not enough to make it cut fuel anyway....

Fuel pump choice has a lot to do with HP

I suggest using a walbro but just be careful when installing it the filter is kind of flimsy and if it falls off and anything particulate wise gets in the pump they die very easily.

Stock FPR is fine for up to 450-500 hp even

so, this isn't the problem. damm then what is it?
everything in car are stock parts.
could this be the MAF? i current use the single cam KA one.
