casting will cause immediate turbocharger damage upon
startup.
a. install four
3 ⁄
8
” diameter, 1 1 ⁄
2
” long studs in the turbo
mounting flange. install a 1 ⁄
2
” diameter, 1 3 ⁄
4
” long stud in
the rear of the turbine inlet casting, behind the turbo
mounting flange. Use anti-sieze compound on the
threads.
b. install the rear turbine inlet casting support brace
where the upper lefthand transmission bolt was
removed. On automatic transmission models, install
the brace with a
1 ⁄
2
– 13 x 2 1 ⁄
4
inch hex bolt through the
round hole (not the slot). Make sure the stud on the
rear of the turbine inlet casting is positioned in the slot
on the brace. lightly snug the bolt.
on manual transmission models, install the brace
with a washer between the brace and the transmis-
sion. Use a
1 ⁄
2
inch sae washer on 5-speed models, or
the 3 ⁄
16
thick spacer washer for the 4-speed models. if
the vehicle uses a loop clamp at this location, first slip
the
1 ⁄
2
inch bolt through the clamp before installing the
bracket.
c. Use a
1 ⁄
2
– 20 collet stainless locknut and 1 ⁄
2
inch
sae washer on the stud at the top of the rear support
brace. snug the nut and washer against the brace fin-
ger tight. see Figure
16 for correct locknut installation.
Important! alignment of the turbocharger and
intake components is determined by the tight-
ening of the two lower nuts where the inlet casting
bolts to the exhaust manifold. The following outlines
the alignment procedure.
a. install exhaust gas temperature pyrometer probe in
the
1 ⁄
4
nPT boss near the turbo mounting flange. Use
anti sieze compound on the probe threads. if a pyrom-
eter probe was not supplied, install a
1 ⁄
4
” nPT hex pipe
plug.
b. install the 5 inch diameter o-ring on the intake mani-
fold inlet flange (make sure surface is free of oil, dirt,
old gasket, etc.).
c. Temporarily set the turbocharger in place on the tur-
bine inlet casting and secure it with a couple of
3 ⁄
8
– 24
stainless collet lock nuts, finger tight.
D. set the pressure chamber casting in place on the
intake manifold. Make sure the pressure chamber
drops over the o-ring. install the pressure chamber
with a
3 ⁄
8
– 16 x 4” bolt, 3 ⁄
8
” an washer, and 3 ⁄
8
” sealing
(o-ring) washer. lightly snug the bolt so the pressure
chamber can be rotated slightly on the intake manifold.
e. adjust the position of the turbocharger and pres-
sure chamber to provide the best side-to-side line up
of the turbo compressor hose joint while providing
clearance between the turbine heat shield and the fire-
wall. additional firewall clearance may be obtained by
slightly bending the turbine heat shield at either side
of the slit in the shield. The turbine inlet casting can be
adjusted for position by tightening the two nuts at the
exhaust manifold studs. start by alternately tightening
the nuts until they are evenly tight against the casting
flange. if the side-to-side alignment is off, the turbo
location may be adjusted by tightening one nut and
backing off the other. Tightening the outside (upper) nut
or loosening the inner (lower) nut will drop the turbo
