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!

    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
