2. SUPERCHARGER MOUNTING BRACKET
A. For 1999-2002 vehicles, the driver’s side coil
mounting bracket must be relocated 1” to make
room for the supercharger inlet. Follow the
steps in the coil relocate schematic (see
Fig. 2-
a, 2-b) using the supplied 6mm hardware
unless noted. Only four of the original mounting
holes are utilized.
B. Unbolt the coil bracket from the valve cover (5
stud bolts).
C. For 2000-2002 vehicles, insert the supplied small
breather into the end of the 3/4” hose that was
originally connected to the stock air intake plenum.
D. Remove the two electrical connectors from the
throttle body. Open up the wire loom until the MAF
sensor wire has about 15” of free length (about
where the #2 injector wire joins loom). Wrap the
MAF wires with electrical tape and cover with the
supplied plastic wire loom. Wrap the remaining
plugs with electrical tape and plastic wire loom
as factory installed. Reconnect the connectors to
the throttle body.
E. Clean the front of driver's side head of debris.
F. Bolt the mounting bracket to the head with two of
the factory bolts and the two supplied 45mm long
bolts. (See
Fig. 2-c.)
G. Make sure that mounting bracket is seated directly
on the machined surface on the cylinder head
and that no wires are pinched.
H. Tighten the four mounting bolts to 37 ft/lb
(50 N·m).
