Hey so my 33 is making noise when in neutral when I push my foot on the clutch the noise goes away I have been told that this is the thrust bearing! I was wondering if anyone knows a good mechanic in Adelaide who is not to pricey and will replace it going to do my clutch at the same time!

If it goes away when you're in Neutral and your foot is OFF the clutch - its the thrust bearing.

If it goes away when you're in Neutral and your foot is ON the clutch - it's the input shaft bearing. This often goes with the cluster shaft bearing. You may also be getting a whine whilst driving which goes away in 4th gear as well in that situation - as that's the only time there's no pressure on the cluster shaft.

My gearbox has both of these symptoms - and has done for about 5 years - steadily getting worse. I'm at the point where I want to get the gearbox professionally pulled down and assessed for repair or replacement - cos I'm not comfortable with it - especially how loud it gets after a long road trip (Adelaide -> Melbourne, for instance)

My input shaft bearing is doing it, does get pretty annoying but not too much to worry about from what ive been told. I had the outer bearing changed and didnt fix it, was told the centre bearing is pretty expensive to change so just to wait and rebuild when I need or buy another box.

Acutally the input shaft bearing is around $170 and not something you can really do yourself without proper tools. My guess is the thrust bearing, if its a slight whirring noise, pretty normal on skylines, my last thrust bearing/clutch did it, ive since had the gearbox out and completely apart chasing a seperate problem and was told it was all fine. Id almost garuntee that my new thrust bearing will do it as well once its in, no real biggie

    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later. 
    • Silly question, as I bet you've checked already, but the motor turns over by hand yes? I suspect Neil has a spare starter, though if not, I believe I have a spare R33 (or two) starter.
    • Yeah just run one of those posts to the Link like GTSBoy said. From google it looks like a "mishimoto boost controller" is a manual boost controller. Since you already have the link just buy any MAC valve and plumb it in where the mishimoto is now. Wires to the solenoid should come from the Link's / standard loom boost control wiring (I guess you have an r32, not sure if it is gtst or gtr, if it is GTR where is a 2 pin connector near the engine bay fuse box/injector resistor for that purpose, assuming the standard boost controller is gone)  
    • No. The ECU's hose is for a connetcion between the plenum (assuming single throttle body, not ITBs) and the ECU's internal MAP sensor. This is the primary load measurement of the ECU - so you need to get this one right. This has NOTHING to do with the boost contol. The wastegate also needs to see a boost signal - but it is actually far better for it NOT TO COME FROM THE PLENUM (again, assuming single TB, and not ITBs). This should come from the turbo's compressor housing (assuming there is a nipple on there, which there might well not be), or on the boost pipe somewhere between the turbo and the TB. On the pipe from the turbo to the intercooler is usually most convenient. The boost controller is then located between that boost source and the wastegate, ACCORDING TO THE CORRECT PLUMBING DRAWING FOR THAT BOOST CONTROLLER. There is no general diagram or instruction that will be correct for every case. Then the other ports on the plenum are for purposes such as Duncan described. If the boost controller has an internal MAP sensor, for a boost display, etc, then it will want to be hooked up there, alongside the ECU and the FPR.
    • Ok gotcha, so one post to fpr  another to bov  and I have the mishimoto boost controller and a link g4+ so I’d just have the tuner set it up properly. For the last two from plenum post throttle to  ecu/ boost controller, I know that I have a hose coming from the ecu that I was confused about so I assume that’s what connect to the boost controller from the ecu? And then the last is just from plenum to boost controller then to wastegate?
