if your gonna hold onto the car its worth doin the waterpump aswell. think it was 120 from nissan and is behind all that. mine started leaking from tell tale about 120,000 and saves pulling it apart again

yeah iv got the the cam seals, yeah i would but going over seas for a hol at the end of the year so i cant afford to spend much on my car this year other wise i would stick on my t4 turbo.

T4 turbo? eh

Check the timing after you're done with a timing light. Something I didn't when my timing belt was done, and the guy that did my belt didn't know it either appereantly. Someone gave me the tip, went and got it checked. Timing was at 21 degrees, while the RB25DET is supposed to have a timing of 15 degrees.

+1. I have the same issue which is getting fixed at the end of this week. The timing belt was done on my R33 and the timing was set to 10 degrees for some reason. As far as I am aware a manual RB25DET is 15 degrees and an auto RB25DET is 20 degrees.

Tips:...

*Mark the valve timing

*Seal the water pump good

*Make sure cam / crank seals are in 100%

*Check ignition timing afterwards

*Once the new belt is on, turn the motor over 2-3 times

*Locite on the crank bolt and make sure its tight!

*If you can, torque the bolts

*Make sure belt tension is correct

Thats all I can think off atm. :/

how do i suppose to tell how many degrees is mine in?? becoz i just changed my timing belt recently too and i notice my gear ratio is a bit different when i change gears, the acceleration goes up more than usual everytime i step it i guess??

Easiest way is to go to a garage that uses a timing light. Shouldn't be expensive, and done in a matter of minutes. The timing is adjusted through the CAS, and it's really a matter of millimeters, so if you're not sure about what you're doing, let someone else do it. When the timing is really off, it can do some nasty things to your motor in the long run.

sweet, that might be a good idea then, take it to a mechanic to get the timing checked once iv changed the timing belt. This might be a stupid question but is the cas the comp in the car or what? Im not bad when it comes to hand on shit seeing as im a aircraft mechanic and i should be seeing as i do it everyday haha but when it comes to other shit im hopeless haha. Thanks for all your help.

    • 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
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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.
