Hey Guys,

Just got outa the car, and this has only just started happening about half an hour ago...

The car drives no problem normally, but the Tacho wont relect the revs accuratley.

Ok heres what happens the revs go up to 2K then wont go past, in fact they start creeping backwards steadily back towards 1K.

Would this be a problem with

-Tacho Buggered.

-ECU Issue

Or what else??

Just wondering what i should start pulling apart first, anyone got any ideas?

The most logical place to start would be the solder joints on the back of the dash cluster.a dry joint could possibly cause this but it does sound abit weird that they start going backwards.

If not the solder joints even just spray some contact cleaner on the connectors that go into the back of the dash cluster and maybe give a bit of a scrub with a cheap tooth brush. But in either case you would expect it to get better as the revs go up (because electrically the voltage is increasing)

Cheers

souns simialr to the problem soarers have with blinky dash, thats is the solder joints cracking apart with age, my old jzz30 used to do that, after 30 minutes or so the joints expandedand made contact again, sounds similar?

My Fuel gauge does weird stuff like this. I will have a full tank for example and sometimes it just goes all teh way down to below the E. Like I have turned my car off, no fuel light comes on so I assume it just lost power to it. Then it comes up to just under a quarter then back down again. To get it to work I usually need to go round a right hand corner really fast or belt through a roundabout. Then it comes back up again. Pain in the ass really.

thanks for the tip!

My tacho has begun going beserk...

Driving along reading fine, it'll flip over to the stopper past the red line, then back to zero, then oscillate at some random value ~2000rpm above where it is actually...

BIZARRE.

Anyone seen something similar?

      Neil's R33 Gts-t Build

      There's no way they left the factory like that. In R chassis there is nothing stopping the steering wheel being put on one spline out from straight, and then adjusting the steering arms to "correct" it (sort of). As well as the indicator cancelling there would also be an issue with how tight you can turn in one direction to the other. The other (less likely) possibility is that the "clock spring" (the circular electronic part that allows the wheel to turn while still having an electrical connection for horn and any other buttons like cruise) might not be in place correctly. I don't have any pics of the R33 (or Stagea) setup but there would be a circular locating tab which sits in the steering column to have it straight...if that is not seated properly then the indicators may not cancel at the right point (and, you might also get a HICAS error since it would think you are driving in circles)

      Ceramic turbine damage to engine - what did yours do?

      It will mostly be bad scoring on the bores, which you can almost certainly fix by machining for oversize pistons. I have to say, I am super surprised that any standard turbos made it 35 years down the track before exploding!

      What's the difference? I would have said that between the front and rear axle lines, there's no noticeable diff between a GTR and an NA 2-door.

      It will be salvageable. It really doesn't matter what is damaged. Opening up a 30+ year old motor for a rebuild immediately means a complete rebuild of the head anyway. Damaged valves just means an opportunity to put in some nice new ones. And in the modern day, why would you not throw at least a nice set of pistons at something. And if you're doing that, why not rods, and ARP fasteners, and so on.
