hey guys,

no i didnt make this thread because i want a louder BOV or something

I recently blew my stock r33 gtst turbo. and i now have a GT-RS in there, but the tuner is having some issues getting over 300rwhp

the engine keeps knocking if he tries to push it any further...zzz

comp test and leak down test have been done, and everything seems fine. still cant find the prob

i have the usual mods

exhaust

fmic

pfc

avc-r

z32 afm

740cc injectors

pod

fuel pump

the question is though, the ebc is set to 17psi

but why is the bov releasing shit all air, being very quiet. i have tried putting the stock bov back one, and that one is also very quiet?

shouldnt it being louder as the car is now running more boost?

it is a LOT quieter, sometimes cant even hear anything compared to when the stock turbo was in, and the stock turbo was running 11psi only

and i also notice the suction noise from the pod is also quieter

so is less air getting into the engine? is something restricting it?

all i can think of is that some bits of the compressor wheel from my blown turbo is stuck on the turbo side of the fmic core?

or am i being a noob and is this normal? lol

i dont really care that the bov is quiet now, i just wanna know if there is a problem

cheers

comp and leak down test has been done b4 tuning so i know the engine is fine

i know it's running 17psi because it is set to 17psi on the ebc and also it shows that on the boost gauge

so all this doesnt sounds normal? more boost should make it louder right?

well thinking it over again, if the EBC and boost gauge is reading 17psi means the turbo is boosting, so boost is there so no it shouldn't be the turbo..it an interesting problem you hav there.

    • 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
