  • Turbocharger nut size? (seriously.. This is a clean thread)

    After looking online and finding nothing useful.

    Does anyone know a place to find nut/bolt sizes and specifications?

    I'm looking for the nuts on the exhaust manifold where the turbo bolts to as well as the down pipe size.

    Pretty sure the studs in the exhaust manifold are M8 x 1.25 threads, based on what I just measured with calipers and a thread pitch tool.

    I don't have a turbo handy to check that side, I must have taken it home or something, because I can't find the extra exhaust side housing I had kicking around on my desk.
