What Intank Pump Will Deliver The Most Flow? Nismo?

I might then try relocate the surge tank so that I can get my oil cooler back in for the driveline

Move the oil cooler.

I'd rather not, it has oem mounting brackets and fittings

Thanks for the info Nick

I actually need to see what my intank pump is, fitted back in early 2000s but it did support 366awkw back in 2004

[Deano 1]

Could u take a pic of the tranny cooler next time u get a chance. I'm interested to c how its setup

[Marko R1]

Here it is from my workshop manual

its got its own little pump & interestingly enough, the core is an Earls item (well, it is an ADM GTR so what would u expect as these were fitted locally before sold)

Ah, transfer case cooler. I have never seen one of those before, I can't remember if the Gibson cars ran one...

Now I am wondering how hot my transfer case is getting.

hi guys,

curiosity got the better of me so i decided to pull my intank pump out...how did this pump support 365awkw when i had the car tuned back in 2004 (2.6ltr bottom end with sard 700cc & hks gtrs turbos)? how is this possible as it looks like the oem pump to me - can someone pls confirm if this in fact the factory pump for an r32 gtr?

i did have the relay added to the fuel pump harness wiring to increase the voltage but that was it - hmmm

[Marko R1]

I have now confirmed it is an r32gtr pump but can't find the flow rate on this unit...I'm still baffled /surprised that it supported 365awkw

Are the surge tanks really nessesary, 2 nights ago I throught to myself I'm going to put a end to all this talk about surge tanks and test my setup.

Got some decent windy roads around my way, they all private of coarse.... So my tank was low, like the light was on and the needle only just on the E white line.

And I was into it, throwing it into the corners, coming out of them sideways foot flat, up too 140+ and back down to 40 around some of the bends...... Not 1 drop of surge, nothing it was like I had a full tank of fuel..... This is 330kw -5's on 98, but still it was a low tank.

I don't see the need for a surge tank in a street/track car.... And for a track car, just go buy a fuel cell.....

Keep it simple guys, less sht goes wrong.

And now I understand why you don't have surge issues Dean...I took the entire fuel pump holding bracket & harness out (which sits in a track at the bottom of the tank) & now I am much more comfortable about running just an intank fuel pump. The OEM system has a surge tank which by my calculations holds just under 1 litre of fuel & this is constantly replenished by the return line which is the black fuel line in the pic with a zip tie on it. The return line runs directly back into the base of the surge tank & obviously if the tank has more than say 10% fuel, the height of the fuel line will also overflow into the surge tank from over the top which is the opening where the fuel pump sits in its cradle.

Verdict? Under car surge tank is coming out & my 'Bugatti Veyron' pump will replace the OEM fuel pump...not much modding required to make this work.

The pierburg should drop in easily & provide all the fuel you should ever need .

Where did you pick up your pierburg from ?

i bought it from efi performance.

i just noticed that the supplied fuel sock doesn't work, the mating diameter is about 5mm too large - where can i source a fuel sock, any ideas?

[scotty nm35]

Just remember, at WOT there is very little fuel being returned to the tank.

Can't EFI supply a sock? If not, I may be able to help you out...

[SilverECR33]

I got a Nismo Intank, heard of a fair few cars that make over 400 with this pump, on 98, E85 will need more flow. im about to turn the wick up soon on it on 98, and see if it can make the numbers.

thanks I've emailed EFI and I'll call them tomorrow. If I have no luck, I'll be in touch

[Marko R1]

update. i spoke to efi performance today & was advised that all i need to do is run a '-10 push lock hose' between the pump inlet and the filter & job is done

i asked about retaining my intank pump & running the pierburg inline without surge tank (under the car)...not a good idea as the pierburg will run my intank dry hence best that i remove the intank pump & run the new pump intank with the removal of my surge tank/044 setup.

they ran a car tuned on e85 making 500whp & didnt hit the limit of the pump (e85 needs approx 30% more flow).

they also ran this pump on multiple cars making over 500kw atw with 98 & have never hit the limit of this pump

Did you have a look at the new walbro 460lph. The specs I've seen says it will flow 5.6l/min @5bar and 13.5v compared to that of the 044 that flows 4.16l/hr @5bar and 13.5v it looks as though it would be great for e85. Can't see why this pump wouldn't be good enough for 500rwkw on pump or 350rwkw on e85.

thanks for sharing - now makes more sense as to how my oem pump supported 365awkw..."Nissan R33 Skyline GT-R stock. This factory Nismo fuel pump was tested to flow 252 lph at 43 psi and 13.5 volts."
