Hi guys,

My R33 Gts-t is squealing bigtime on cold starts.

I searched the forum and found a thread on how to check the tension of the alternator belt. This diagram was posted.

Basically, when bolt 1 is completely tightened on, bolt 2 is still adjustable by hand? its not locking into place.

anyone have any ideas as to what to do from here? cheers.

have you positively identified it as the alt belt squeal? a lot of it is starter motor pinion squeal

hey mate thanks for your response.. Yeah I'm fairly certain it is.. without sounding too noob..which I am to turbo cars.. whats the point of unlocking the first one if the second one can just be tightened or loosened by hand regardless? is the tightness of the first one the one i should be adjusting?

cheers

As noted by lachlanw, bolt (1) locks the alternator to the bracket and bolt (2) is your belt tension adjuster.

So you'd back off bolt (1) slightly, adjust the belt tension using bolt (2), then tighten bolt (1).

Then tighten bolt (2) slightly to stop it from rattling loose.

If none of this is working, I'd guess your adjuster thread is stripped.

If so you can back off bolt (1), lever the alternator out until you get correct belt tension, then tighten bolt (1).

      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
