Gidday fellas,

I'll soon be purchasing a big pump + adjustable press reg for a series 1 r33 and am interested as to what people are using on their '33s.

Got in touch with a company called Powerflow awhile ago and got some good prices on in tank bosch 044's.

I've seen a few press regs in nengun's site - one there looked good which is a nismo item - adjustable and looks very similar to the stock '33 unit.

(great price too!) Just wondering if anyone has purchased one of these and are happy with the result?

Anyone use any other products/can recommend anything for me?

ie Sydney kid with that r34 that made 265rwkw?

Thanks!!

Yep, I have a Nismo adjustable fuel pressure regulator that came from Nengun, it bolts onto the end of the standard fuel rail, I'd say $180 well spent.:D

Im running a larger bosch in tank pump with a malpassi adj fuel reg. 248@rear out of stock injectors....works well....(yes im in the process of getting 840cc items from japan, i know stock items arnt intended for this power).

there are many different brands and options, my advise would be to go with what whoever is tuning it is recomending and familiar with....

Thanks for the replies.

Looks like I'll order the nismo item and 044 pump.

I've been told there's two different inlet sizes on the pumps in the '33s - has anyone else found this?

The injectors i'm running at the moment are stock but I plan to get some nismo 740cc ones in conjunction with a turbo upgrade after we tune the pfc, but that'll be awhile away.

Still waiting on the pfc but when we dyno I want the fuel system up to scratch as it was leaning out last time with stock boost/computer.

Anyway - hope to post up a dyno graph soon!

Hi

I just ordered one of the malpassi's, any tips on fitting it ?

a pic or two would be great !

thanks

I've used a Malpassi reg., seems to work fine on mine. I've used the standard fuel pump with an external Bosch 911 to make 450rwhp, but now have an 044 to push past this figure, it's running from a 3lt surge tank.

Hope that helps

    • 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
