Hello all.  I am soon starting an RB conversion into my 280Z that is on its way from the USA.  Has anyone seen a ZF 6HP26 (auto trans that are installed in a FG FALCOON) installed behind an RB block?  I am planning on using an RB30 block with a RB26 head (I once saw some new RB26 heads in the USA - but not sure if they are still available).  Thanks.

There are a bunch of ZF8HP swap kits out there for the RB26. A ZF6 is mostly the same thing mechanically as far as I can tell: https://www.e90post.com/forums/showthread.php?t=1569774

Hello joshuaho96, I did come across the GURU info, but I only found that they do kits for the ZF 8 to a BMW engine.  I prefer to stay with the ZF 6 rather than the 8 speed ZF - the 6 speed is plentiful here from behind a BARRA.  HA - if masking tape and rope was strong enough to hold the ZF to the RB - ALL my problems would be gone - HA.  Mechanically - possibly there are similarities between the ZF 6 and ZF 8 - but the bolt up bit is the crucial bit.  More research is required by me.  I did note that possibly I can start with a RB25 twin cam head and get it to work with the RB30 block - now I just need to find a suitable head to start with.  Thanks.

      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

      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.
