Take the 26 sump to a decent fabricator and ask him to cut the diff off it and weld it up. The 26 sump has quite a bit of strength to it. While they are at it put a decent extension on it to your oil side of things is sorted. If your in Sydney Performance Metalcraft know what to do with it :)

While the engine is out i would also put a decent oil pump on it so you dont have to worry about pulling it out again any time soon

The 25 sump and oil pan doesn't just fit straight on. There is some fabrication that needs to happen. After you bolt up the 25 oil pick up. The oil pan wont just go on. After you figure out how to get it on you will notice that the oil pan is hitting the base of the oil pickup. Then if you want you can grind the pickup base which I dont like to do because it can lead to oil problems later because of how much you have to grind off to fit the oil pan on the block. When I did it I simply modified the rb25 oil pan in that section. I heated it up and shaped the side in a round fashion to clear the oil pickup base. Then if I remember its still has one bolt I had to sacrifice which was no big deal as the sealant (silicone) took care of that.

What I would do if I did it again is as mentioned above use the 26 aluminum oil pan and cut the diff off and weld in parts that needs to be filled in.

Go on RaceFab and look at how they did it on there site. Or just buy one from them.

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      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..
