Can anyone confirm the size of the three studs from the up-pipe to turbo inlet on turbo . It's either 3/8" - 16 x 2 1/4" or M10 - 1.5 x 2 1/4"
I want to replace these studs but need verification before proceeding.
Thx in advance.
Did the bolts end up being metric or standard? I don't know how to spec the springs but those are shoulder bolts. Bolt Depot has a vast selection of fasteners in every grade and material you can think of, that is where I would check.
The bolts on the OEM Garrett Turbo are Metric.
The three up-pipe double threaded studs ("Set Up Stud") are M10 - 1.5 - 57mm
The two down-pipe "Shoulder Bolts" are M10 - 1.5 - 68mm > with the "shoulder" 48mm length (12.5mm thick) and thread length 20mm
Thanks for the lead.
