I currentyly have a series 1 rb25det in a 32 at the moment and i am doing an engine change on this and thinking of putting a rb25det series 2 engine from a 97 skyline.

I have mixed respones and mixed reactions from people on the forums and mechanics. Some say that you can put a Series 2 engine onto a Series 1 wiring loom/harness.

Can anyone confirm that this can be done otherwise i will need to source out a series 2 wiring loom/harness.

Is there any difference in the word wiring loom and wiring harness, different people use different words.

Can i series 1 wiring loom support a series 2 engine?

(Thinking the problem will be the coil packs since the wires on the series 1 go into the back of the engine where on series 2 there is a wire for each injectorm, is this correct?)

Any comments or help on this would be benefitical.

Cheers

harness is different as the series 1 has the little black box up the back... cant remember the name of it. ITs a sprak amplifier or something

Series 2 motor has the amplifier thingy on the actual coil packs themselves

which is totally different

yeah i realised that was the difference, i have heard that instead of connecting the plug to that little box up the back, you can run the 6 wires directly into the coil packs themselves?

Anyone tried this?

the coil pack wiring from the s1 unplugs and just plug in the s2 coil loom.

hrmm interesting....

I have a s1 motor and loom and recently purchased splitfire s2 coils.

The coil plugs on the s1 loom dont fit onto the s2 coils so i need to use s2 plugs instead. I also need to remove the ignitor (black box at the back) and wire the wires into the coil loom.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      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
