i have just got a profec b2 and i installed it onto my r33 gtst, now i am having problems as it doesnt want to stop boosting at all. I have checked the boost lines and none of them are kinked. i am not sure which way the filter for the boost line into the back of the unit is supposed to be? and also the wires running from the black booster that connects to the intake and actuator the wires for the clip on the back of the unit in the car were off and im not sure which way they are supposed to be? could someone please help?

Hey guys, jst a quick question....

I know in the instructions a clicking sound is normal while the solenoid vavle is operating but how loud is it meant to be? i can hear it quite easily from inside the cabin...

Cheers

While on the topic - with that hose that comes out the back of the main unit... would that T off into one of the hoses off the back of the plenum? or would it be better to disconnect the stock boost gauge hose off the back of the plenum and connect that hose straight into the back of the plenum?

Make sure you rubber mount it, I just put piece of rubber of an old bike tube between the soleniod and bodywork.

I just T'd it into one of the hoses coming of the plenum.

As for the clicking, it shouldn't be that loud. However this shouldn't mean it is faulty. You may just have a loud unit.

Dunno, i spsoe you could take it back and try another one?

Im not overly concerned about it as its not affecting anything, just was wondering if they are all that loud. I do have it rubber mounted so that shouldnt be a problem. And it does say that a clicking noise is normal so im not going to stress bout it too much...

thanks for your replies tho!

cheers

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