Hi Jeff, I found real good (Black-Oxide Steel Spacing Stud) high strength 8mm x 1.25mm studs from McMaster Carr for my turbo hardware needs and after using hundreds of them I haven't had one fail yet! I'll post their grade later when I find that info but I they're grade 8 or better!
For the cast elbow to the wastegate housing assembly;
Short stud, use part number 93275A030 (M8X1.25mm Sz, 50mm L, 20mm & 20mm Thrd Lengths) and cut 8mm from one end and 4mm from the other.
Bottom stud, use part number 93210A032 (M8X1.25mm Sz, 80mm L, 27mm & 12mm Thread Lengths) and cut 2mm off of the short thread end so it doesn't run into the waste gate linkage / valve and remove nothing from the other end.
Other long stud (the longest one), use part number 93210A033 (M8X1.25mm Sz, 95mm L, 31mm & 12mm Thread Lengths) and leave the short thread end alone and remove 9mm from the long threat end.
As far as the other studs you need just go to McMaster Carr's website and search Black-Oxide Steel 8mm x 1.12mm Spacing Studs.
