The oem hardware used on the MR16DDT is not the greatest. Due to how its constructed and designed, it has a tendency to snap off when removing the studs/nuts, or get jammed up when reinstalling.
Here is a solution to that.
This kit replaces:
-The three downpipe bolts/stud on the turbo
-The four studs from the turbo to the manifold (comes with two nuts, just in case two studs wont come out for you.)
-The eight nuts that bolt the manifold to the head.
This kit is perfect if you are installing a new turbocharger or replacing the downpipe. It wont prevent the oem hardware from snapping on its way out...but it sure will help things to back together easier!
