Fuel Pump In R33

[subzeroR33]

^^^^Anybody someone must be an expert when it comes to what type of fuel pump to use .

[MANWHORE]

James, what it comes down to is:

how much you can afford to spend

whether you'll be putting it in yourself

how much power

if so, how good are you at modifying to fit

if not, how good is your mechanic

Basically, what it comes down to, is that the tomei and nismo variants are designed to be straight bolt in. In terms of straight bolt in, I mean literally, comes with everything down tot he last hose clamp, tank gasket, brackets, everything.

I personally like the tomei/nismo pumps, and with the aussie dollar at its all time high, the price is cheaper than ever before. I remember when I first got my car, to get a nismo pump, you were looking at about $800 (less parts people back then too, so they charged whatever they liked).

If you don't mind fabricating stuff, you could fit something like a bosch 044 intank, or run a lift pump and use an 044 externally.

Ok thanks for that, with the future mods i should make around 400rwkw. What type of fabricating is involved with installing the 044 if they are an external pump. When i pulled out my pump it seems to be a nismo brand with the brackets or are the brackets already standard.

[MANWHORE]

Well, the standard pump has a bracket.

It's not hard to install an 044 in tank. You just have to modify that bracket, mount it onto that bracket, and squeeze it into the tank (the pump's quite large, so it'll need some maneuvering, but you shoudl eventually be able to get it in without it resting on the bottom of the tank (otherwise it'll be really noisy).

nismo - 311 aud from greenline... and i was about to go through nengun!

i think you may have the 044 mixed up with the 040.

yeah, well, I made the mistake of buying the nismo from nengun - $400 for it, and it took 6 weeks. They decided to send it after a few abusive emails.

Then the prick got smart with me!

Nengun = lose

Greenline = win

Nismo pump = double win

check out the excellent quality.

Came with an eom style bracket, new o ring for the access cap, and all sorts of shit. NO assembly is required.

[joeyjoejoejuniorshabadoo]

yeah, might even pay the extra 30 schmux greenline want for the splitfire di's... 6 weeks is a bit much

[MANWHORE]

Nope, I said 044 for a reason. I have never liked the 040. It always seems to cavitate/fail.

I've fixed numerous cars which have had cavitation problems/failed pumps with 040s in them.

Where did you get 311 AUD?

Email from Greenline:

NISMO Fuel Pump R33 GTSt: 33,264 yen

Shipping: 4,100 yen

TOTAL: 37,364 yen AU$363

[Birnie]

Try a quote on the Tomei pump, it's the same sheeet but cheaper.

I have the Tomei and looks identical to the one Mafia has, including the bits that came with it.

$311 is soo good !

The Bosch 910 pump is only rated to flow ~400hp. If thats all your after then throw a walbro in.

Walbro's are good pumps for low power levels but start pushing 450+hp and don't mess around and throw in either a Bosch 044 or Tomei/Nismo pump.

All bosch pumps can be mounted in tank with only slight modifications.

Generally....

Bosch 910, 200 l/hr @ 5 bar (73.5psi), supports 220 rwkw

Bosch 975, 228 l/hr @ 5 bar (73.5psi), supports 250 rwkw

Bosch 984, 228 l/hr @ 5 bar (73.5psi), supports 250 rwkw

Bosch 040, 235 l/hr @ 5 bar (73.5psi), supports 260 rwkw

Bosch 044, 330 l/hr @ 5 bar (73.5psi), supports 360 rwkw

'Apparently' running a check valve on the 044 helps prevent cavitation and keep it quiet.

Not sure where you got those figures from but they are different to what I have especially the flow rates at those pressures. But your calculations on supporting horsepower is wrong. 200l/hr = 3.33L/min of fuel flow therefore you would need 6 555cc/min injectors to use all the fuel which places the power output at around 550hp using a BSFC of 0.55.

The biggest thing you've got to remember is that as the pressure drops the flow rates go up substantially - more so with bosch pumps.

Thanks manwhore and the others for the advice. It will come down to the Sard and the Nismo pump.

And NENGUN i have never heard a good thing about there customer service very slow postage and no after sales service.

Hey mate that set up looks different to mine, my pump was clamped on and sat towards the end of the bracket with the sock pretty much attached to the pump.

[Birnie]

Yeah, that sounds like an original bracket with either the standard pump, or an upgrade pump (bosche or GTR) clamped down the bottom

Heap of pics comparing original/upgrade pump here:

Yeah mate it must be a GTR pump as it has the nissan logo stamped on it.

I decided to have a mechanic install my bosch 040 today, he modifyed the cradle etc then went to install .... told me it cant be done, the o4o is physically larger than stock pump and will not go down far enough to draw fuel out effectivly and i would be forever filling it to make sure there is enogh fuel, all the reading i have done on the 040 says it can be done??????

you need to find a new mechanic.

im a builder and it only took me 10 minutes to install my 044 in tank with a falcon v8 fuel sock and its wisper quiet.

if a mechanic cant install a 040 in the tank then he has issues.

back to trade school for him.

All the hose is fuel rated from pirtek,

with no surging or running out at 1/4 full.

its not a hard mod, yet everyone goes running to the nismo etc.

just make sure you rubber mount the pump

and you can hardly hear it running

044 FTW

I just took a look at the pic, I was un aware that i would need to modify the pump also, down the bottom where the sock is attached, how is this done??? take the mesh of the bottom of the pump and?? Edit: thats an 044 eh?

Are you sure he is mechanic? are sure he is not a downy?

040 Can be done easily, just requires common sense and locating the clamps correctly so they don't hit the edges of the tank.
