Hi all, just bought a r33 gtst and on the way home I started getting a idle surge hovers around 800-1200 almost stalls sometimes but will regain idle after a few seconds to a min.

Not sure if it has a aftermarket bov that is causing the problem.

Also a rubbery squeaking sound from behind timing cover. Could it be just a tensioner.

Has a gizmo boost controller too wtf how do you work it???

Ok pulled off the AAC valve and it was a bit covered in engine breather gunk.

Took the solinionds off it washed in diesel than cleaned with carby cleaner put back together installed, than went for a drive and it's sweet.

Purrs like a kitten all the time.

Noise behind timing cover has gone but I suspect it's a belt tensioner, geeeeeez $300 for a kit

Seen the gates racing one on eBay a lot cheaper are they a good kit for these engines.

Also noticed a very high pitch squeal from the turbo like a dog whistle, it's only on very light throttle every now and than. Sounds like and old bluebird CA18 turbo sound. Weirdest sounding turbo out there if you ever heard one.

Still hold boost but the pull is not consistent from mid to high revs, only very noticeable. But than again it's got 2 1/2 or 2 3/4 pipe than goes to the rear muffler and reduces to about 2 lol previous owner was defected. Will this all reduce high range power maybe a stupid question to ask.

93 R33 GTS-t do they only come with a tiny front mount?

No need for a racing (blue) belt unless youre pulling mass power, and theyre noisy. Just go genuine Nissan.

Should be a tiny side mount.

      What brakes on R34 GTT(Europe)

      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.
