For 1993 and early 1994 applications, follow
Steps 9-13.For 1994 and Later applications,
skip to Step 14.
WASTEGATE MODIFICATION
9.
unbolt and remove the heatshield from the
turbocharger. On models with a support
brace between the turbocharger and the intake
manifold, pull the cdr valve out of the valve cover
and unbolt the support brace, then remove the
heatshield.
10.
remove the “e” clip from the pin on the end
of the wastegate control rod where the pin
attaches to the wastegate lever on the turbo outlet
elbow casting. use care not to lose the “e” clip.
see figure 3.
11.
unbolt the wastegate actuator bracket from
the turbo compressor cover and remove the
wastegate actuator.
12.
install the high boost lever, provided, over the
pin on the wastegate actuator rod. see figure
4. install the “e” clip on the pin.
13.
reinstall the the wastegate actuator with the
high boost lever installed to the original
wastegate lever on the turbo outlet elbow. use a
5 ⁄
16
-24 x 3 ⁄
4
” hex bolt, 5 ⁄
16
” an washer, 3 ⁄
16
” long spacer
and 5 ⁄
16
-24 lock nut as shown in figure 4. Make sure
that the end of the bolt and the lock nut will not rub
on the outlet elbow when the lever is rotated.
reattach the actuator bracket to the turbocharger
compressor. Move the actuator rod and lever
through their rotation and check that binding does
not occur. correct as necessary. note: some
resistance is always present from the wastegate
actuator. reinstall the turbocharger heatshield and
the cdr valve.
EXHAUST SYSTEM
14.
remove the factory exhaust system by first
prying the pins from the rubber frame
mounted hangers. spray some Wd-40 or similar
lubricant into the holes to make this easier. remove
the factory clamps from the pipes and work the
joints loose, from the rear forward. if the slip joints in
the pipes will not come apart, heat them with a
torch until the pipes will separate. On 1994 and later
vehicles, unbolt the catalytic converter assembly
from the turbine outlet pipe. loosen the turbine
outlet pipe clamp at the turbocharger, and remove
the pipe.
For 1993 and early 1994 applications, follow
Steps 15-16.For 1994 and Later applications,
follow Steps 17-18.
15.
loosely clamp the new turbine outlet pipe to
the turbocharger.
Standard Cab models: install the intermediate
pipe onto the turbine outlet pipe with a 3” exhaust
clamp loosely in place. install the muffler onto the
intermediate pipe with a 3” exhaust clamp installed
loosely on the inlet and the 3 1 ⁄
2
” hanger clamp
installed loosely on the outlet. insert the tailpipe up
and over the rear axle and insert it into the outlet of
the muffler. see figure 5a.
