Have had the old girl for 5 years now, and it's been the best car I have ever owned.... until.... If you started it cold, about 30 seconds into your drive it would start a rhythmic 'miss' between 1500 & 2000 rpm, if you could get her above 2000 it would stop missing. Once the car got to operating temp, you can turn the engine off, then back on and it will run like a dream!. although I have noticed the old smell of un- burnt fuel. Now we are closer to winter, in the mornings when you first start it up (to warm up the engine) it will surge up and down till it warms up. Now over the last 3 months I have spent around $1000 trying to sort this, the first computer diagnostic said front Cam sensor Done (no change) light came straight back on during cold missing, the next error that threw up was the rear Cam sensor... replaced... no change... next was the AFM .. no change..... too scared to see what comes up next... now a rattle has started to come from the engine when you put her underload, and sound like the timing is still off. Anyone been through this scenario? Any advice would be much appreciated. Thank you!

Don't know how much info we have here on that motor as all the Stagea in Australia are mainly the VQ25DET or VQ35DE, maybe ask as well on a V35 skyline forum.

also other cars that came out with this motor are: A33 Cefiro, Cedric/Gloria.

maybe change the thread tile to include VQ25DD for better results.

      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.
