Hi all, I am having trouble with my S2 R33 GTST, have had a look around the forums but so far nothing has really helped.

The problem is when the car gets warm it just dies (can crank it over but wont fire) and wont start again until cold.

When the car is cold it starts first turn of the key and will drive around and wont miss a beat until its warm and then wont start again.. The problem has been occuring for a little while now but thought it was fixed after unplugging the ECU (Nistune) it didnt happen for about 150k's (the car doesn't get driven very often)

Have swapped the cas and afm (Z32) for known working units and it didn't make a difference, plugs look alright and the Splitfire coilpacks are only around 8 months old also unplugging the coolant temp sensor doesn't do a thing.. Car also drinks a fair amount of fuel round about 300 Kilometers to a tank on 98.

Could this be an issue with the tune? any help would be greatly appreciated cheers.

Does it crank slow ? Like a flat battery ? Could be your starter motor solenoid sticking/faulty, a friend had an old hilux that would start fine when cold but once up to running temperature, if he turned it off he wouldn't be able to start it for a few hours till engine was cool again.

Hey guys sorry for the delayed reply..

Answers to previous comments..

defari- temp gauge says abit under half when it dies

blind_elk - Wont start if i give it any throttle just floods it and runs like shit when it eventually fires haha..

Lrs94- Nah doesn't crank like a flat battery cranks like normal

Kane_R32 - Fuel pressure is good after car shuts off

mlr- Where abouts are connections on chassis and block?

UPDATE- Turns out the cas i tried turned out to be an RB20DET one plug was the same but apparently the timing is different? And i ran the car the other day and when it got to temperature it didn't shut down and even took it around the block and let it sit at home idling and didn't die? :wacko:

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
