Hi

Just purchased a GTR R33. I was giving it some stick the other day and it backfired and after that it wouldn't idle good, I could not really drive it to move it off the road because it didn't have any power, anyway, I have checked coil packs, spark igniter, AFM's, plugs and still can't find the problem. My next thoughts are, could the timing belt have skipped a tooth, it runs like it is running on 3 or 4 cylinders, while the car is idling, I unpluged coil packs one at a time and found that the front cylinders aren't burning fuel (no difference in idle), it idles with plenty of black smoke (rich) coming from the exhaust and the front cylinders are wet. Has anyone witnessed this or has someone had a car that skipped a tooth on the timing belt? Also, does the RB26 bend valves when timing goes out via a skipped tooth? I have done a compression test on each cylinder with the results of every cylinder being the same PSI whilst cold, it also holds the compression. The cars timing belt was changed at 70,000, it has now got 120,000, it seems legit since I received log books with the car and everything matches.

Any advice would be greatful.

Denis

Sounds like a a cooler pipe off has blown off

Well guess what? you were right! took it to Advan Performance Centre in Auburn, they found it straight away, however, all of last week it was at Castle Hill Exhaust/Performance where I had my VE SS worked (332rwkw) on (spent $12,000 on it through them, now sold), it looks like Skylines are beyond them, they had it for 5 days and could not work it out, I even told them to check the cooler pipes, they told me it would'nt be that, plus they left me with a nice dent in the passenger door, "thanks Dave, your an ass", anyway, I want to give the boys at Advan Performance Centre a big thanks, and to Dave at Castle Hill Performance a F$%kyou, all you did is screw me around the whole of last week, telling me you can't find the problem, you don't have time, you are busy, all I can say is, you don't give a shit about existing customers and a nice way to do business, you wont be seeing me again,

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
