Yeah well mine is just about to shite itself. Having to start the car with a friendly tap with my starting stick (hit starter with breaker bar). Wierd it didn't show any signs of failing just happened at the shops on the weekend. So like someone said above any from a RB20 / RB25 / RB26 etc will fit but will it make a difference wether its manual or auto?

Having to hit it make make it spin is a direct pointer to the SM "poling" - the bushes at either end of the armature wear out and when current is applied the shaft moves sideways and jams diagonally hence belting it jolts the shaft back into a central position that allows the shaft to spin.

The moral of the story is, if the brushes etc are OK, you may be better off finding a sparky that can pop the casing and fit new bronze bushes. This will be a lot easier than trying to source a new / second hand unit and most sparky's will give a good warranty on the work done too, well worth the spend IMO.

Yeah I've pulled it off now, am going to take it to a sparky tomorrow. When the problem started happening I would turn the key and there would be no sound at all and the clock on the dash would die. I thought battery at first but I've got a volt meter on my turbo timer and when turning the key it would still stay at or just below 12volts. And head lights weren't dimming either. Ended up just tapping it with a hammer and it would start but the starter sounded like it was struggling (like the battery was almost dead). And this moring had to do it again and when I got home nothing again, no matter how much I tapped it. But I couldn't even hear the solonoid clicking there was nothing (so I thought it must be that). When I got it out I just tried power to the solonoid and it clicked in and out with out a drama. Didn't try to spin the motor itself though so I'll see what the sparky says. My only other thought is the battery has had it. Has full charge lights aren't dim or anything but my not be cranking enough amps. When I got the car back (after a swap BACK) just a couple of weeks ago the battery died after just 10mins or so with the stero on, checked the levels and it was almost dry (took almost a full jug of water) but has been good for the last week or so, so maybe the battery is stuffed.

I found out the hard way that you CAN overfill a battery - mine died a few days after I'd topped it up right to the brim! Only out enough water so that it just covers the plates...

Oh, and take it to your local spare parts shop (one that sells car batteries) and see if they have a battery tester - my first replacement (the one I bought after the overfill incident) had a dud cell, so they exchanged it under warranty.

Yeah I only filled it enough to cover the plates, thats how dry it was. I don't really care which is causing the problem but now that I've got to the effort of pulling the starter off I kinda hope thats it....was a BITCH to get off and am guessing its going to be just as fun putting it back in. Just that one bolt right under the intake plenum. :D

      Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By Duncan · Posted

      Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly

      oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
