compressor hose joint while moving it slightly toward
the driver’s side of the vehicle. reversing the tighten-
ing will reverse the movement of the turbocharger.
Optimum positioning should provide approximately
3

”
gap between the turbo/pressure chamber hose joint
while maintaining firewall clearance and about
3
⁄
16
”
gap between the pressure chamber and turbocharger.
rotational alignment of the hose joint may be adjusted
by squeezing the compressor snap ring (use snap-On
no. Pr-569a snap ring pliers or equivalent) and rotating
the compressor housing. see Figure
17.
F. Once the best alignment of the turbo and pressure
chamber has been established, tighten the nut and bolt
to secure the rear brace to the turbine inlet casting
and the transmission. Make sure both nuts at exhaust
manifold are tight. see Figure
15.
G. install the side support brace between the turbine
inlet casting and support bracket on the intake mani-
fold. The end of the brace with the greater bend goes
against the bracket. see Figure 15. Use a

long hex bolt,
7

– 20 nylock nut,
7

– 20 stainless collet
locknut and three
7

” s.a.e. washers. see Figure 16 for
correct locknut installation. Tighten nuts and bolts at
side brace and intake manifold bracket.
remove the turbocharger and pressure cham-
ber from the engine. Cover the turbo flange
opening and intake manifold openings.
install oil inlet block an o-ring on turbocharger,
using two 8mm x 30mm hex bolts (bolts are
gold colored for identification) and two pairs (4 total)
of ramp lock washers. see Figure
19
for proper instal-
lation of ramp lock washers. install a
1

nPT x – 4 an
elbow fitting in the oil inlet block. Use Teflon tape on
the elbow threads. aim the elbow as shown in Figure
18.
a. run a bead of silicone sealant around the oil drain
tube about
1
⁄
4
” up from the unflanged end. insert the
drain tube into the grommet behind the intake mani-
fold while keeping the throttle cable(s) and wire loom
between the oil drain tube and intake manifold. Push
the drain tube about
1
⁄
2
” into the grommet.
b. install the turbocharger on the turbine inlet casting
using four
3
⁄
8
– 24 stainless collet locknuts and four
3
⁄

an washers. no gasket is used between the turbo and
the casting. The upper nut on the driver’s side can be
more easily accessed by reaching between the turbo
compressor cover and the firewall on the driver’s side.
c. bolt the oil drain tube against the flange on the bot-
tom of the turbocharger center bearing section. Use
a drain gasket, two 8mm x 20mm hex bolts (bolts are
gold for identification) and two pairs (4 total) of ramp
lock washers.
D. Place a 2
1
⁄
4
” diameter hump hose and two no. 36
hose clamps onto the turbocharger compressor outlet
connection.
e. set the pressure chamber onto the intake mani-
fold with 5” o-ring in place. install the center bolt, an
washer and sealing washer. align the pressure cham-
ber and tighten the center bolt. Make sure the pressure
chamber contacts the intake manifold so no gap exists
at the junction. This assures that the o-ring is captured
and sealing.
F. Center the hump hose between the turbo and pres-
sure chamber, then tighten the two hose clamps.
NOTE: On C-6 automatic transmission models, check
that transmission kick-down rod does not bind or hang
up on anything in the vicinity of the turbocharger.
G. bolt the anti-depression valve to the turbo compres-
sor inlet elbow using the original bolts. Hose nipple on
anti-depression valve must be oriented up. an optional
valve adapter is required on pre-’87 models.
H. slide a 3” diameter by 1

” long silicone hose and
two no. 52 clamps onto the compressor inlet of the
