K-Series 75/ZT 1.8 NASP and 1.8T In-Tank Fuel Pump Question.
 

What are the differences ... if any ?

Does the Turbocharged version of the K-Series require a higher Fuel delivery rate or pressure ....or what?

Thanks in advance.

The turbo pump assembly has a 4.55 Bar pressure regulator fitted. I cant say if the electric pump itself on the NASP is the same or not. Perhaps its just the pressure regulator that is different ?
From my experience with a poorly running turbo model that had only 2.8 Bar pressure the running was horrible, Once fixed I obtained >4 bar with the pressure gauge fitted at the Schraeder valve on the manifold and normal running was resumed.

On the turbo model the item at the other end of the manifold at timing belt side is described as a damper and not a regulator. The NASP does not have this feature.

The NASP is supposed to have a 3.5 Bar pressure at idle, so this would suggest a lower rated regulator is fitted to the pump assembly in the tank.

Here's my experience with the turbo model pumps with reading taken.
