    Inconel studs and Copper nuts for turbo applications

    I notice that inconel studs and copper nuts are somewhat more accessible these days than they used to be.

    Is it worth running them on a mid range turbo car, or just overkill?

    I used inconel on my bigger Barra high mount setup now. Copper always seemed to come undone on factory low mount

            K nuts or any similar type of deformed nut is the go for hot bits.

              Never had much luck with washers, just wind out the entire stud instead.

              Anyone used these things:

                  Nope. Nordlocks are much different.

                    Nord locks are serrated cone washers. But if the stud starts winding out then you lose all tension on the washers anyway.

                    The Stage8 fasteners above should stop the stud from winding out too as it will bottom out on the nut.

                      nord locks aren't cone washers, they're 2 piece serrated washers with inclines between them.

                      with nord locks the stud can't start to wind out unless something goes horribly wrong, or you've used them incorrectly (you can't use any other washer in conjunction with them).

                        I did the works with inconel studs and copper locking nuts (a kit from GCG I think. was about 70 bucks) and nordlock washers. cost 80 bucks for all the bits for the flange.

                        turbo still attached. would bang again.

                        the secret with nordlock washers on a stud is the stud thread pitches must be LESS than the ramp angle of the nordlock washer or it can wind itself out, that way if it starts to loosen, it actually clamps the stud tighter.

                          These were the only things that could get my entire hot-side to hold together.
                          Soft roaders represent an excellent compromise between the needs of the hardcore 4x4 user and the convenience of a city hatchback. Its clear to see why they have become so popular in todays society.

                            I've not tried the nordlocks, but the things that made a difference for me were:

                            Preventing the exhaust from hitting the body

                            Using the Nissan lock plates

                            Lockwiring the nuts to the lock plates


                            There must be a trick that the OEMs use to assemble these things, as they seem unreliable once undone from factory.

                              I bought my nordlocks from Anzor Fasteners. they were around $3.00 each for 316 stainless M10 (turbo flange) and $2.50 for M8 (manifold flange) from memory

                              https://www.anzor.com.au/washers/nor.../316-stainless

                              other option is from RS-online, they sell Heico ones in bags of 10
