hey guys,

saw a spotless R33 SII today, only 70 000kms, the owner was an international student and hard on english

He produced a dyno sheet for the car that read 276 rwhp.

the thing is while it drove perfectly it felt more like 200, or even like standard - he couldnt explain to me if the boost had been turned down (very hard on english)

Is that power possible for the below mods?

- Greddy FMIC

- Apexi cold air induction

- 3in Xforce TBE

- Apexi Neo AFC

- Greddy EBC

- Bosch fuel pump

Could be acheived with mentioned mods. but boost is definately increased. 276hp isn't much at all. it's only 200kw.

it also comes down to what you are comparing it with. to be honest, 200kw (270hp) in a r33 doesn't feel that fast. it is fast, but not that fast. because the rb25 makes it's power down low and pulls all the way to redline it doesn't have that turbo rush that some other cars have. one day i hopped out of my 33 making around 200kw and into a s13 making about 160kw and it felt much much faster. i know they are a lighter car, etc, but because of the way that they don't really start to pull until higher in the revs you get a feel of the sudden rush of power. the 33 just doesn't feel that quick, until you have something to compare it with. i know that my old 180sx that would've been luck to be making 150kw (was stock other than cat back exhaust and 9psi boost) felt quicker than my 33, however once you were up against another car, or the clock, you saw that the 33 was actually reasonably quick.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      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
