Anyone now someone who is missing a Black 180sx reg S843AVM....

It is parked outside my place and looks like it has been tampered with and dumped...

SAPOL said it has not been reported stolen but from everything I can see it looks like it has been.

need a lil help guys, was driving the gtr just cruising at 60 changed gears nice n slow n I felt a funny twitch in the clutch pedal and then next time I pushed the clutch is was a lot heavier all of sudden.

pulled over check the fluid levels all looks ok, then I noticed when I got back in it every time I pushed the clutch it was making a noise like gas escaping. This was in the car not under the bonnet.

so I hear this is possibly a vacuum leak in the booster? anyone got any other ideas?

anyways I drove it home and it felt fine aside from the weird noise and being heavier clutch than normal, went into gear fine no crunch.

What im wondering is, is this doing any damage to the clutch? I have the nismo coppermix twinplate so I don’t wanna stuff it up but its normally light as a feather and id actually prefer a heavier clutch pedal.

o and this car is starting to p me off

finally got it into a workshop and there tellling me its the thrust bearing is worn out and itll cost 550 in labour to rip the gbox out to replace it. they are suggesting i wait till the clutch is worn to replace it.

ive got no idea what the thurstbearing is, will it damage the clutch or make it wear out faster? it seems to feel alright other than the noise at the moment.

anyone know how much it is to rebuild a nismo twin plate anyways :P

I'd just leave it for the moment but $550 seems a bit too pricey for that type of work, it's a little brass "ring" worth about $3 from Nissan.

To rebuild a Nismo twin plate is about $900ish from NPC

Luke i think your thinking of the spigot bearing that sits in the end of the crank and the end of the input shaft runs inside it.

The thrust bearing is on the bearing that rides on you input shaft and it what pushes (or in the case of a pull type clutch, pull) the "fingers" on the clutch when you press your pedal.

Regardless both parts are worth bugger all but it is a gearbox out job so would there's a fair bit of labour involved.

I would take the mechanics recomendation and wait until your clutch is stuffed and do them together becasue the labour cost will be the same.

It won't damage anything but if you end up with a scretching noise when you press the pedal then the bearing has colapsed and you will then need to change it.

Having said that the symptoms that you have described don't sound like thrust bearing to me as that would have no effect on pedal feel.

Your thoughts about the clutch booster sound more on the money to me. The other thing it could be is a broken pivot point for your clutch leaver. I have had the same thing happen to my car and after month of not figuring out what it was eventualy (on an SAU cruise) i put my foot and the pedal and the clutch didn't engage which led an emergency pit stop at windies lookout. Ended up driving the car through the hills back to Campbelltown with no clutch which was a lesson in matching revs on gear change.

if its not a daily driver ya could tear it apart, find the problem, fix/replace the part and whack it back together yourself.

it would be an educational experiance and you could get to know your car a little more in doing so, it would make for a fun and intresting weekend.

FYI my brother-in-law David (Red back on SAU) is running his R33GTR (with R34GTR Nur engine in it) at the Bathurst Motorsport Festival this weekend. FB group below if anyone want to check out pics/join.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
