ill send you a little link with guys running one 044 in tank and making 400kw + and not one or two cars a fair few,

Edited by WARLORD

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

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?

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... :)

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

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."

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
