Righto so i just got my R32 GTR back from the tuner

The car made 375rwkw at 18psi on pump fuel before the Fuel pump decided it couldnt flow anymore, that and the injectors are at 75% duty so they'll be swapped out as well..

and before everyone jumps in and tells me the nismo should flow more, i dont need to hear it. Yavuz tunes a certain way and its been working pretty well so far

Current set up is:

Borg warner 83/75 on a twin scroll manifold

Brand new Nismo intank pump that been wired to recieved the correct voltage, (so i know its pumping as much as it can)

Standard fuel rail and reg

Sard 800cc injectors

standard fuel lines

Now what i want to do is run the turbo at 25psi which will/should make in excess of 430rwkw on pump, BUT i will also be running an EFLEX tune with ethonol...

ive already got the ID 2000cc injectors on the way, and ive decided to get a twin entry fuel rail with an aftermaket reg, fuel lines will also be upgraded.

The decision that has to be made is what fuel pump set up to run, keeping in mind i will only be using the car for street duties mainly and light track days...do i:

1. Run a surge tank and have the nismo feeding two bosch 040's,

2. Sell the nismo and run twin intank 040's, or

3. Buy one of these big suckers and run a "Y" pipe so both sides for the rail can be fed

problem with number 3 is that ive heard it doesnt flow as much as it claims

what do u guys reckon? if ive missed anything let me know

cheers

What ever you decide, don't buy an aeomotive pump...

My personal preffrence is a large single pump... whack a surge tank in if you'r looking at alot of track work- or not if you dont.

Keep it as simple as you can.

Has anyone run a twin nismo intank setup before? I've heard of twin 044's so I imagine it's much the same yea?

I want to try and avoid the surge tank and obvioslusly I can get two Bosch pumps for the price of 1 nismo, I dont mind the noise of the 044's but obviously nismo is the preferred :thumbsup:

Simple is good, though I'm not really sure what else is out there in terms of big single intank pumps... Anyideas?

It'll need to flow well and truly more then a nismo

I'm not sure if it will flow enough for 430rwkw though especially on ethanol... that is some serious mumbo!
