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.

Well, the standard pump has a bracket. :laugh:

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).

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

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

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.

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.

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:

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.

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
