The Deatschwerks ones are great i have been using them for about 1 year now with no problem what so ever. if they are put in the right way you will not have a problem. Another good thing is that the std ecu can run them as well.

my point is why bother paying so much from Deatschwerks when they are easily avail locally much cheaper.... between $100 and $150 a set for exactly the same thing..

Right.. Since no one can tell me a went and tryed to find an answer..

Estimated power goal 250rwkw, Estimated 290KW at flywheel

Right retract everything I said

. Standard injectors at standard pressure (36-38 psi) 370 cc = 370 bhp (~210 rwkw)

Use adjustable fuel pressure regulator to get pressure up to 45 psi and the standard injectors will flow a bit over 400 cc’s. Which is enough for 400 bhp, ~240 rwkw. You will need a fuel pump that can flow 400 cc’s X 6 = 2.4 litres per minute = 144 litres per hour. Any of the standard GTR fuel pumps will do that, and a bolt on Nismo FPR ($150 from Nengun).

So technically 480cc will be close to 90% max .. But shit they'll work

SAU search brings up so much crap, can you please exclude the dribble it brings up

do all Nismo injectors have nismo etched into them

is it the only way of telling if they are Nismo

Does any one know this? We had a look and the R34 nismo ones have nismo etched into them and come in a nice little nismo box. My R33 ones have nothing on them and came in a poxy brown box :( lol

PM-R33 two things

1. ill let you know when I get them lol.

Your sig seems to be stolen from me!!! How dare you!! I nicked it from someone else first!@

Alright then, Seems greenline are the cheapest option but dont sell nismo.

Again ill just ask will 480cc be enough for my application? if stocks are handling 200kw I dont see why 480 wouldnt handle 250rwkw

at 250rwkw my 555cc injectors were at 50%

440cc GTR injectors just make 300rwkw..

Surely thats enough of an answer?

Bringing up an old thread but i figured it was better than starting a new one.

I have just recieved my nismo 555cc injectors for my rb20det r32 and i have just noticed that the nismo 555cc injectors for the 32 gtr have the same part no. So im wondering if i need a gtr resistor pack to run these injectors, the instructions have a diagram that looks suggestive of this.

cheers

Well this got bumped so I might as well a little bit of info that I have picked up about Sard injectors.

I installed 800cc Sard injectors and they were a straight drop into my R34 GTT. No extra parts (collars) required. However, they were apparently very tough to tune for. They keep dumping excess fuel into the cylinder which results in some awesome flamage which is fine if you're into that sort of thing but not so good for fuel economy or my cat and the area around my exhaust needs pretty frequent cleaning lol I wouldn't recommend them if you're after a no fuss install/tune.

Cheers.

And another since it got bumped post. I got 250rwkw and Nismo 480cc injectors. They max out sometimes but I have a rich tune atm for all the track work. I have had it as high as 272rwkw at about 98% injector duty.

Im looking at the Nismo as an upgrade for my GTT but heard Sard also produce 650cc injectors with no mods required. Target hp is around 450-500hp max for my T04E turbo setup with PFC. Which would be a better buy and easier to tune both power & economy using datalogit software?

One last thing, I hv the Nismo fuel regulator bought a year ago but haven't installed yet. Will I be able to squeeze more fuel if both FPR & PFC working together with standard 370cc injectors?

    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
