Thats kinda nice coz you can see the fuel pressure.... kinda

you wont need an FPR for 11psi+pod mate

I run 16psi (GCG) on stock ecu, pod, full split exhaust/highflow cat/catback and GTR FMIC. The only thing you need to look for is R&R which i occasionally hit and fuel isnt that great :D

Have a look at the Nismo adjustable FPR (~$140 from Nengun) it bolts directly onto the fuel rail, so it saves buying a fuel rail fitting, hoses and clamps.

As used by Sydneykid and Mines, so it can’t be that bad

:D cheers :D

SK, I have just ordered a nismo fuel pump and regulator "as pictured" along with a set of nismo 600cc injectors to strengten my fuel system and be in a position to upgrade to r34n1 turbos or other low mounts GTSS maybe for track and targa.. I have a standard R33 GTR except for apexi powerfc and boost controller which made 283rwkw post an exhaust change. My question is after fitting the regulator do you maintain the standard pressure as it now "guaranteed" or should you increase it and if so to what pressure.

RWKW...naa mate, I make AWKW :P.

Yeh, RB25 in a Stagea. Made 160awkw with the coilpacks breaking up above 5000rpm. Peak power is still climbing at like, 7000 rpm too.

GCG is the turbo, a highflowed standard turbo. www.gcg.com.au

R&R is rich and retard, the ecu retards ign timing and richens up the mixture. Feels like a bit fat bang, then it slowly builds up again and off you go. Its pretty annoying...

BTW, that was on a hub dyno... the best kind of dyno

Hey guys, just a quick and possibly stupid question :)

Do the RB20s have a FPR as standard? If so, is it that little object that sits in front of the inlet manifold that plumbs into the fuel rail? And if it is, why the hell does it have a little rubber hose that connects the side of it to the inlet manifold? I don't understand why an FPR would need to read or use inlet pressure??? But that's because I'm an idiot :( I see that one SK posted also has a little nipple that looks like the same position as the one on what I think is my standard FPR.

Please help me out of this confusion :)

Ben.

Anyway, this thread is about fuel regulators. I wouldn't trust a cheap one. I tried a Malpassi but wasn't happy with it - noisy and inconsistant pressure.

When it comes down to it, it's a very important piece of gear and it could cost a shitload if something goes wrong.

I'm not one of these 'give me brand names or give me death' kind of people but there are some things I wouldn't trust to the cheap end of the market.

exactly why i'm going to a Nismo FPR... no machined aluminium, no anodizing, just something that should do it's job and is virtually Nissan sanctioned... while cheap to boot!

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

      By GoHashiriya · Posted

      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.

      WTB R34 GTR Guard Liners

      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
