Coming from somebody who's stuffing one into an S13, save yourself the trouble!! Getting a decent rb26dett (good compression and leakdown #s) took me 5 months with an importer's help, I haven't wired it in yet so I still don't even know how it runs. Ofcourse I live in the U.S. where importing from Japan is much more difficult, you aussie's get first pick DAMN-IT.

Here's what I've gotten out of my own prodject.

The SR is by far more complementing to the Silvia's weight distribution. Not only does it weight around 180lbs less, but because it's 2 cylinders shorter it's center of gravity is much closer to the center of the car.

The SR is a very high strung motor when pushed to the natural hp #'s of the rb26.

The fitment issues of the smallest siliva, the S13, are not a problem with motor mounts from mckinney. http://www.mckinneymotorsports.com/ These guys know more about swapping any rb into any silvia more than ANYONE. Give them a call, only if you're serious, these guys are Extremely helpful and knowledgeable.

If I were to do my project all over again, I would be very tempted to go with the SR, as I DREAD, the day my RB needs internal parts. I don't think I've ever seen parts prices so high !! :D

My car would definately dominate yours on a drag strip, but unfortunately, my love is for circuit racing, for which a properly modified SR would be ideal. Goodluck man, let us know what you figure.

My two cents is just an added bit to your search, but if you want to know what's possible and what's not, call those guys at Mckinney!!!!

      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.
