Exhaust Manifold Stud Kits

G'morning all,

I am looking to get a fella out to repair the thread on the rear most manifold stud hole on the RB20DET (if anyone can recommend someone good whom services the Gold Coast that would be awesome) Upon seeing that the average prices I could find on exh mani stud kits were $115 and UP, I took it upon myself to find an alternative.

Went down to the local nut "n" bolt (Coastal Bolts and Fasteners Labrador) and matched up the right studs. They are M10x1.25 for anyone interested and 14 of them (two for spares) cost me $25 or $30. throw in some washers and .10c a piece and some nuts for the same, it starts becoming a WHOLE lot cheaper than buying a kit. Without the spacers that I am asking about, the whole lot has cost me around $40. With the spacers it would cost me $50 MAX. Which is a whole lot better than the $115 or so to get the kit. $175 if you are getting them from Nissan themselves.

However, a dilemma I am having, is I have recently noticed that in the stud kits, are not only washers but actual spacers, and to top it off they are not all the same, cylinders 1,2,3 and 5 have one type, whilst 4 and 6 have another.

I can not seem to find anywhere what sizes these spacers are. Would there be any chance that someone on here might know what sizes they are? For the two different spacers needed. I believe they are spacers, they look like they are.

As you can see in the image above, there are 12 washers, 8 thick spacers and 4 spacers a little bit thinner. All I need to know is what thickness they are. If anyone has some old exh studs left laying around with the spacers on them (PLEASE, not just a stud with a random spacer you chucked on there, but the actual required spacer) could you please measure the thickness of them. I need the measurements for both the thin and thick spacers (not the washers, just the spacers)

Kind Regards,

Michael

Hey mate, i have one of each in front of me. Also if you can find a manual, it's on page en-76. Looks like the same for rb20-25.

Measured with a tape measure (cause thats all ive got)

Smaller one is 5mm thick, 11mm inside hole and 22mm outside diameter.

Larger one is 5mm thick, 11mm inside hole and 24mm outside diameter.

Hope that helps

      Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?

      It looks like it needs a big worm gear drive on it to control the rotating, not a few sloppy pins!

      R32gtr sputtering and stalling

      As Duncan said, first there was OBD, which few cars used, then came OBD2.   Now an interesting point, OBD2 isn't even for what you want to do. OBD2 is for emissions testing. There is some sensor data on OBD2, but it's up to the manufacturer what they're putting on it. Most scan tools operate on UDS, which like OBD2 is a standard built on-top of CAN. UDS specifies how to structure a message, what very limited things mean such as "read memory address" but it does not specify what is stored in which memory address, that is all up to the manufacturer. You either a scan tool compatible with that vehicle, or to know how to reverse engineer all the data, which can take a VERY long time and a lot of vehicles to get it right. Oh and then the manufacturer does a firmware update and changes what's where... Ask me how I know that as fact Oh, and by the time you've got the scan tool that supports all the manufacturers stuff, well, you're back at "But a consult cable and the Nissan software" The main difference being most manufacturers software these days works with the same hardware readers, as the readers are built to support J2534 which is another standard for how the PC communicates with the tool to make it do specific things on the car...

      Rotisserie is fully assembled apart from centre connector which obviously isn't required until the car is on it. It packs away fairly neatly and doesn't take up too much room. (Now that I actually have some room after my clean up!) Overall very happy with the quality of it.  Assembly was a piece of piss.  The only thing I didn't like was that the pins that lock the rotation lock wheels in place were a bit of a dick in a bucket scenario. It allowed the arms to rotate a significant amount even when locked in place.  To fix that i measured up the hole and went and grabbed a couple of 18mm fully threaded bolts and a thread tap to suit. I ran the tap through top and bottom so it was threaded both ends.  Then just threaded the bolt through both sides.  It has made a massive difference which hopefully you can tell in the before and after video how much difference it made. 20250207_161431.mp4   20250207_161431.mp4 Hopefully back working on the car over the next few weeks.   20250207_162801.mp4

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.
