removed from the standard manifold as they sometime stick in the manifold when removing
the injector, its easiest if these seals are removed from the injectors and installed into the SC
manifold for assembly) from the standard manifold and reinstall on the supercharger manifold
(fuel rail bolt torque 19N.m) Note injector keying, blue circles.

6. Supercharger installation
6.a. Ensure that the engine looms and hoses are clear from the intake ports / manifold face
and the front center section of the engine. (Note: ensure main cross over loom is sitting at as
height between SC and loom is limited).
6.b. Install the fuel crossover pipe as shown.
6.c. Remove tape from the inlet engine ports. Inspect Supercharger manifold assembly includ-
ing the ports to ensure there is no foreign objects or debris.
6.d. Using 2 people lower the supercharger manifold onto the engine. Avoid sliding the
manifold across the heads as this may damage the manifold seals.
6.e. Once the manifold is in place it should sit at on the heads with no rocking and there
should be a small amount of movement front to back and side to side. Ensure that all wiring
and hoses are clear and SC isn’t sitting on the vacuum by-pass actuator.
6.f. Install the standard manifold bolts to the center bolt hole and then install the front and rear
bolts.
6.g. Torque the manifold bolts to 10Nm in the sequence shown and then 25Nm in the sequence
shown below.

the supercharger). Use the worm drive clamp supplied and secure (access to clamp is in east
west plane and tightened by using a long screw driver or a ¼ drive socket with long extension
from right side of vehicle).
6.j. Connect the brake booster line to the vacuum line attached to the supercharger manifold
(under the rear of the supercharger, reuse existing clamp for booster side of hose, no clamp
required on supercharger side).
