i searched and searched but could not find the answer to my question... so please do say search!
i have a d15b on 5 psi with a greddy kit and my question is will a stock gsr fuel pump be efficient enough 5 psi? i think a walbro will be overkill... i wanna get a few other opinion.. thanks

 

It may be ok but do you really want to risk you motor over a $90 part.

 

Hell, your stock pump is prolly fine.

Just fork over the $ for a quality product like the Walbro. They make smaller sizes other than the 255lph. They make a 190lph.

 

I ran a stock pump in mine for a few years when I was only pushing a few lbs....but you never stay there for long, and you'll end up putting the pump in it sooner or later, so you might as well do it now and not risk it

 

my stock pump in my 90 cx (same as all 90-91 crx/civics) was good till 190whp... never tried to go past it.

 

i swapped in a 95 gsr fuel pump and its runs better now. so im guessing it flows better than the stock cx.... anyone know the stock lph for civics and integras?

 

If Im not mistaken, I think all of the older honda fuel pumps were the same....now that doesnt mean yours wasnt starting to go out and thats why you saw a performance increase
