Hi guys

Just wondering how good the R34 GTR fuel pumps are as i am about to fit 750cc injectors and power fc (keeping standard turbo's for now) and have been told the GTR factory pump will be more than sufficient for this (by an actual tuning shop who you would think would try talk you into fitting a new one for they're benefit)and are good fuel pumps to over 300kw which i wont be getting near with these mods. It would save me fitting an aftermarket pump till i'm ready to upgrade turbo's AFM's etc. Can anyone else vouch for this or has experienced the GTR pumps limits/performance?

Thanks

I have to ask... Why you are putting in 750cc injectors with stock turbos???

Stock injectors will flow more than stock turbos can make. So sticking with stock injectors would be a far smarter idea, and keep your 750cc items for when you actually need them.

A GTR pump can flow 380rwkw no problem, been done before by two people i know.

Infact there is conjecture as to whether or not the Nismo pump & OEM GTR pump are actually the same part - as there is evidence to suggest they might well be. Wouldn't be the first time Nissan have branded the same part with a different part number and price.

The only thing sticking point, the "OEM" GTR one costs much more than a Nismo replacement, so it makes sense that people just buy a Nismo item.

***HOWEVER*** the pump you have now, is 10 years old or there abouts. I think for a $300 part, it's simply a risk not worth taking. I'd be swapping it out with a Nismo or a Bosch pump. Nismo being easier to install and a bit more expensive. I would honestly change it for piece of mind.

      From Japan and back to Europe, my sh*tbox R34 GTT

      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?

      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
