so my 31 box is slowly on the way out and kinda driving me nuts. had a look a round and i’ve come to 2 possible solutions either rebuild the current one or put a low k wrecker box from a 32 or 33 in but i was wondering if it was at all possible to do so? i’ve seen a few people ask similar q’s but mainly with manual box not with an auto any info is greatly appreciated.

It should be doable. You'd need the TCU, and you'd need to make sure that you got a compatible TPS for the auto onto your throttlebody (have no idea if the RB30 is same same or different....do know that R32 uses a TPS switch only for the ECU and the variable resistor part is for the TCU, and that R33 is different from that). I don't know if the load signals between the ECU and TCU would be compatible (or even what they are, seeing as my first action with a dying R32 tranny was to pitch it and manual convert).

Other than that, it is mostly just mechanical stuff like making sure the tailshaft fits, flex plate and converter are compatible. Speedo drive, etc might be a little bit of fun.

      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

      M35 VQ25DET starter motor

      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..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
