i cant just put a normal rb25det in the engine bay coz normal rb25det is rear wheel drive where as mine is 4wd. it will just cost more.

you can also use a AWD RB25DET engine out of a laurel, gloria or cedric... not just a stagea.

but yes, AWD RB25DET's never came out in a Skyline, and of the cars that it did feature in, very very few of them are manuals. So you gotta be careful with your diff ratios, or risk ATTESA having a hissy fit.

The engine (Stagea RB25DET) for my conversion cost me $3800, 18 months ago. It came complete with an auto box, which I basically discarded (since my 'line is manual).

There is no need to fret about the differences in diffs causing havoc with ATTESSA. It is relatively easy to swap the (front) diff out of your current setup into the Stagea engine. Or fit a Stagea rear diff at the same time. If yours is already a manual, then it's also relatively easy to transfer the flywheel / clutch onto the RB25DET - only requires a new spigot bearing.

RB20DET would be a waste of time. That's why I put the 25 in my 'line in the first place (R32 GTS4) - would be even worse trying to haul around a lard-arse R33 with a gutless RB20DET (but, if you want one...)

      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.
