Exhaust Manifold Stud Kits

[poeticjustice88]

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
