7) Install the turbo pedestal and turbo using the new o-rings, then attach the y-collector to the back of the turbo using the v-band clamp (Figure 9)
a. Turbo pedestal bolts are tightened to 18 lb/ft and the turbo mounting bolts are tightened to 35 lb/ft (according to Garrett).
b. Apply even pressure when tightening bolts to prevent the o-rings from binding and causing leaks.
c. Aligning the y-collector with the back of the pedestal takes some patience. This is why the lower manifold flange bolts are not yet tightened to allow you room to wiggle everything in place. The v-band clamp is tightened to 50 lb/in (that's inch, not feet) according to International.
