flow rate of standard fuel pump

[japmadlad]

I remember recently a thread bout the flow rate of the walbro (255lph) and the standard pump (???). Nobody could find a definate figure for the nissan pump. Well I think I have found the answer. 138
Nismo have an uprated pump which they claim pumps 4.1L/min or 246lph. this is a 180% increase over the OEM pump which means if u work back. The OEM pump runs 2.3L/min or... wait for it...

Drum Roll please...

Source?

Was that specifically for the S15, or the S14?

Nice find :thumbs:

But like Nicely stated I would also like a source or more info.
Spec-R or Spec-S pump? Manual or auto? or are they the same?

I found the figures the other week, It was on nengun site. Posted in the write up about the Nismo Upgraded pump. I'm pretty sure the Spec S uses the same fuel pump as the Spec R.
Heres what it says:

Nismo Fuel Pump - Silvia




Nismo High flow Upgrade Fuel Pump 4.1L/min (at P=294kPa,3.0kg/cm2), an increase of 180% compared to the standard pump..

Work backwards from this to get the figures I stated in my 1st post

Unfortunately, it says the same thing for the S14, but it lists two different Nismo part numbers....
