hey everyone. As stated in the title, is there a center ring that is suppose to be in there around the hub so it is flush with my rim? Someone at the shop says yes I need one. If not a ring, then is it fine the way it is? I'll order one if needed but what is it called?

Rb hubs are 66.1mm

Most aftermarket wheels are 73mm and you will need hubcentric rings. What wheels are you using? If they are off another Nissan such as a 350Z etc they will most likely also be 66.1mm

This is a picture of the rim.

Its just a plastic or aluminium ring that takes up the gap between the hub and the wheel centres to locate the wheel when you put it on. The wheel studs do all the work holding the wheel in place.

Yes, this could cause a vibration. In theory if your wheel nuts are tapered as most are the wheel will end up centered on the hub even without the right size wheel bore or hub rings, but if it is even slightly off the wheel will be offset to the centre of the hub and will not turn evenly leading to vibration that increases with speed.

If the bore of the wheel is larger than the spigot on the hub, then yes, you need a ring. It's not completely easy to see what's going on there, but it looks like there's no gap.

When driving at higher speeds a feel a vibration through my steering wheel that I'm trying to eliminate. So far I've replace tires and control arms on all 4 sides. Now I have to replace the rear wheel bearing. I'm hoping that eliminates it. Afterwards I'll take her on highway to see if it dissappears. They just mentioned it at a garage about the ring and I wondered if that had to do with the driving. If you guys say there is no gap then I won't bother touching it.

It is unlikely that the absence of a hub ring is causing the vibration.  More likely it will be either a tyre out of balance or related to the wheel bearing (Although thats less likely).

Diameter should be 66.1 on the car and the same on the rim or if it isnt you will probably find that it is 73.1mm.  As has been said, take the wheel off and measure it.

To answer your original question the name of the ring that goes around the hub is hub ring. EG:

      Pops when backing off throttle, rough-ish sound through rev range.

      By Duncan · Posted

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
