1.
Remove the wastegate assemblies
from their cartons. There is a right and
left wastegate, identified by
orientation of the logo and the outlet
flange. The outlet flanges should face
to the outside of the engine with the
logos right-side-up when viewed from
the front of the engine.
2.
Install the right wastegate onto the
front of the right exhaust manifold
with the V-band clamp, bolt, and lock
nut provided. Use a small dab of Anti-
seize on the bolt threads. Make sure
the wastegate valve seat ring is
between the wastegate and the
manifold with the tapered side against
the wastegate valve. Tighten the bolt
to the point that the wastegate is
secure but can still be rotated to
position by hand. Repeat this
procedure for the left wastegate. See
Figure 20 and Figure 21
Note: When installing wastegates with
high boost springs, it may be easier for
two people to perform the clamping /
bolting procedure.
3.
Adjust the two wastegates so the
front logo lettering is level on each
one; this will make the side ports level.
See
Figure 22 . Torque each
wastegate clamp bolt/nut to 5-7 ft. lbs.
Install a 10 mm banjo bolt, - 4AN
fitting body, and two crush washers
(found in the wastegates parts
package) in the 10mm side port of
each wastegate with the –4 thread
pointing straight up, and tighten. Note:
washers go on either side of the fitting
body. See
Figure 23.
4.
Install the remaining 10 mm banjo
bolts, barbed hose fitting bodies and
crush washers in the front of each
wastegates with the fitting pointed
down. These are the cover vents. See
Figure 24.
