So it stopped running while you owned it or it has never run while you owned it? Was there any significant event that caused it to stop running?

First things first: check for fuel pressure, check for injector pulse and check that you have spark. On an RB you can simply unbolt the CAS and turn it by hand. You can then hear the injectors click and watch plugs spark without the motor cranking.

Next check for compression. I have a feeling it may have bent some valves when it slipped the belt, but i am only speculating.

Verdict: if it has fuel pressure, injectors pulse, has spark and has compression then it SHOULD run. Cam timing could stop it if it were majorly out, as could major intake leaks.

Outside of the above you should be able to find the issue with those tests.

rb engines, like any other 4 stroke engines. if it has skipped a tooth or possibly more, could definitely stop it running.

Something is broken. The usual course of action is to get it towed to a mechanic so he can diagnose it, in the presence of, you know....the car itself.

maybe check the sprockets on the inlet and exhaust cams and find out what may have causedthe belt to jump otherwise it may do it again

suggest you fit a timing belt kit and try to start the car? IF the motor is f**ked you would need those parts anyway as part of a rebuild , once you have got it all back together then turn it over by hand first

yeah thanks mate i wasn't sure if the rb's were really sensitive to being a tooth out or not but yeah still could be more teeth out on the crank.

welcome to the world of low mount turbos lol

If u got access to a hoist will help from the bottom. Take this opportunity to change the turbos or dumpipes if u need to while its being taken apart

Is that what the problem was, a blown propellor?

what im trying to do is take the head off in the car but i think the intake side is going to be even harder.

So is it turbo or timing (cam gear) related? Or both?

Whys the head coming off?

its turbo and compression related thats why im taking the head off to see what kind of damage there is and to see what course of action im going to take rebuild or just get it going till i have enough money to do a full rebuild

I managed to pull the rear turbo off. Short 13mm combo spanner helps with the dump pipe; tedious as hell.

How the hell did you get the front turbo off? It looks impossible lol

haven't got it off yet almost though and i know what you mean i was sitting there yesterday thinking what the actual f**k lol

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
