Temporarily install the large end of the intake
“boost” tube into the silicone hose on the
pressure chamber. Rotate the turbo compressor
housing so it lines up with the other end of the
boost tube. Lightly snug one of the six bolts on the
compressor housing to secure this position.
Remove the boost tube.
Install a 1 ⁄
4
” npT x -4 tube, 90° elbow fitting in
the oil inlet of the turbocharger center bearing
housing. use Teflon tape on the threads. aim the elbow
so it points up, toward the engine.
Remove the turbocharger from the engine,
tighten all 12 compressor and turbine housing
bolts, and bend the lock tabs against the bolt heads.
drop the exhaust head pipe into place between
the engine and the right frame rail.
slip a piece of
5 ⁄

” Id x 1 1 ⁄
2
” long blue silicone
hose onto the tube on the fuel pump adapter/
drain plate. slip a pair of no. 10 hose clamps over the
hose.
nOTe: fuel lines may have to be detached and
re-routed to provide clearance for the oil drain hose
and exhaust crossover pipe. If metal fuel lines must be
bent, use care not to kink them. do not re-route fuel
lines until crossover pipes are in place so clearance
can be determined.
drop the turbocharger in place over the exhaust
manifold studs. no gasket is used, or needed,
between the turbocharger and exhaust manifold. guide
the turbocharger oil drain tube into the oil drain hose
on the adapter. secure the turbocharger with four 3 ⁄

– 24 stainless collet locknuts & four 3 ⁄

” O.D.
washers. The collet locknuts should be installed as
shown in Figure 10. The nuts will spin on freely and
lock only when tightened. Bolt the oil drain support to
the engine block. Tighten the oil drain hose clamps.
Install the boost tube using the 2” I.d. x 1 1 ⁄
4
” long blue
silicone hose and two no. 36 liner hose clamps at the
turbo connection. Secure upper hose with two No.
40 liner hose clamps. Make sure clamps are installed
behind hose beads.
Bolt the exhaust head pipe and gasket to the
turbocharger with six 5 ⁄

8
” stainless hex
bolts, and 5 ⁄
16
” I.d. x 9 ⁄
16
” O.D. washers. The head pipe
should hug the exhaust manifold as closely as possible
to provide maximum clearance to the frame. nOTe:
It may be necessary to dent or slightly modify the
head pipe on vehicles equipped with quad front shock
absorbers.
Raise the vehicle. Install the right-hand crossover
pipe (3-bolt flange) to the right exhaust manifold
using a gasket, three 3 /

three 3 /

Tighten the nuts finger tight.

transmissions, carefully bend the section of the
transmission coolant tubing that runs adjacent to the
oil pan to provide clearance and heat isolation from the
exhaust crossover pipe, as shown in Figure 11.
