Some newbie questions if I may...

* How much rwhp (or rwkw) can the standard factory Fuel pumps handle ?

* Obviously the more power the more fuel required and the stock pumps are only good to pump so much fuel ? Anything else worth knowing... ?

* What is the typical cost and can anyone post some websites with info/products/prices ?

thanks,

Ben.

You might find it a bit cheaper to go a second hand GTR pump, can get them for 250-300 compared with 500 for a 044.

I have those mods, and I am only making [email protected], at the time it was about 35deg C. What turbo are you getting?

Currently the injectors are starting to show the strain too(up 82.9% when tuned with a Z32 afm, 77.7% when not so well tuned with a sock afm but that was pushing out 191rwkw and pretty lean), so you may want to think about a rising rate reg too.

sorry I'm rambling a bit.

Benm, sydneykid answers some of your quesions on the SDU forum, a thread entitled 600hp fuel system, here is a link

Hope it works as I cant get on to the SDU forum at the moment, bloody server too busy.

Findings from a trusted source differ to that in that link posted above.

I've got a 975 mounted internally in my car.

Begin Cut and Paste

The big daddy Bosch Motorsport pump is part numbered 0 580 254 044, it can flow

330L/hr @ 73.5psi and price is $550.95

The last 3 digits will be different for other Bosch pumps.

975 is a 228L/hr flow @ 73.5PSI at $340.95.

984 is the same as 975 just that the fittings are slightly smaller.

040 is 235L/hr flow @ 73.5psi and it comes with a screen for in tank operation and is priced at $359.95.

910 is 200L/hr flow @ 73.5psi at $229.95.

I know that although the 975 doesn't say its a in tank pump, it can be mounted

internal or external to the tank, maybe all the other Bosch pumps can be

mounted internal or external also.

End Cut and Paste

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
