Hi all, This has probably been covered a billion times before so i apologize if i upset anyone.

Im currently in the process of replacing an RB20e (yuck!) with its DET sibling (including manual conversion) into an A31 and was just interested to know how i go about getting it passed by regency? Im aware some type of engineering cert may be needed but is that all it takes?

Where could i get this done in Adelaide and how much is a certificate usually worth? Should I not bother and just wing it, and if i happen to cop a defect just gut it for drifting? Any help would be greatly appreciated. Cheers, Simon.

Go talk to your department of transport, they should give you a list of registered engineers in your area, then go talk to them about what is required for them to give you a modplate/engineers cert.

Usually it will just be something as simple as upgrading the brakes to the equivalent of the DET model.

varies from state to state. In VIC you'd need an engineers cert, and their biggest requirement is that you have upgraded brakes and handling to compensate for the extra power.

eg: RB20DET brakes, spring rates in suspension, bigger brake boosters etc.

    • 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
