    Manifold to head? M10x1 IIRC and are a pain in the arse to find without going to Nissan

    If they have fallen out the thread in the head could be fooked

    no there m10 x 1.25,

    ebay has them all over the place

    or just use a m10 x 1.25 bolt (fine pitch)

    m10 x 1 is a flywheel bolt incidentally

    or they could be cheap steel and not inconel like they should be.

    Go to Nissan to get them, they're expensive but worth it

    Yeh I'm hoping they have just come loose and not stripped the thread.

    head to manifold studs are not inconel, they are mild steel! (hence why they rust and break)

    turbo to manifold are Inconel,

    which is why any mild steel engineering stud will do the job

    I used these on my RB - the little hex is way too small though, rounds v. easily.
    white '94 s13 200sx scrapped - mapped to 1.45bar. OS giken box, garrett GT2876R, 950cc injectors, ORC twin plate, nistune. 349bhp/325lbft @ 1.3bar CA18DET
    white '96 s13 180sx - type g with more kouki bits - RB25DET, GTR steel twin turbo conversion, RB26 crank & rods. 2.6L VVT twin turbo, SR20 OSG box, OSG STR twin plate clutch, Z32 ECU w/ nistune.

    current status: 180 a bit broken but to be repaired.

    i was toying with the idea of using an A4 stainless steel stud for corrosion purposed but was unsure,

    how did you find them? i take it none have failed?

    dunno yet, engine isn't running

    the only feedback I've got so far is that either they're cut with a fairly shallow thread depth or there was some galling on the threads in the head, they were a pretty tight fit anyway (doubtful they'd ever unwind themselves)

    given that, the torque you need to apply can easily overcome the small hex head for winding in, so they round pretty easily. ended up using the sandwiched nuts technique.
