Looking For Longer Studs On Turbo Exhaust Manifold - Rb25

[shaunzo101]

I am just looking for advice on where i can buy studs for the turbo flange on my exhaust manifold for RB25. They need to be longer than factory. The reason is i am putting on a spacer plate so i can fit my bigger turbo onto the standard exhaust manifold.

[WYTSKY]

any exhaust/ turbo shop

I went to an exhaust shop but they couldn't help me. Was hoping somebody would know?

find a local bolt/fastener specialist, take a standard stud in there and get them to find you one Xmm longer on the turbo side. make sure its high tensile and isnt gonna turn to shit with a bit of heat

Can anyone confirm what size studs are required for connecting manifold to turbo flange?

I just fitted longer studs the other day... umm, I think they were 10mm width x 1.25 mm thread, I had mine stick out 50mm (total length around 65mm, rather a bit longer anyway, then you can always trim them off if necessary) for using a 20mm spacer. If you like I'll go measure them exactly and precisely for you.

I got mine from a local hardware store/machining shop, could probably be found at car parts dealers, garages, heavy machinery workshops and whatnot.

Edit: oh, and for just fitting the regular turbo I think about 30-35mm pegs does it... so maybe a total lenght of 50 mm
