manifold.
Fit the new manifold and retain with the original two top fixings using Permabond A130. Do not fully
tighten. Use new flange head bolt A116W5238F with Permabond A130 at the rearmost fixing point. Take
the nut previously fitted on the foremost stud, and fit instead to the new stud at the centre bottom fixing
(with Permabond A130). Take the nut previously fitted on the centre bottom stud, and fit instead to the
foremost stud using A130. Progressively tighten all fixings to 27 Nm. Secure the VVT valve to 10 Nm.
8. Lay the new engine harness in position with the injector portion in the channel between inlet manifold and
cylinder head with injector breakouts uppermost and aligned with the injector ports. Route the harness
between the new breather pipe and inlet manifold, following a tight line down beside the cylinder head
and block to the back of the alternator.
9. Refit the injector rail taking care to correctly seat the injectors. Ensure the spacers are in place before
securing with the 2 x M8 fixings - 20 Nm. Secure the fuel pipe to the cam cover - 9 Nm.
10. Remove the four coil packs and replace the spark plugs with the new PFR7G items. Torque to 18 Nm.
Refit coil packs to 9 Nm.
11. Refit all connectors on new harness.
12. Fit supercharger nose bracket to engine mounting plinth with new M10 x 50 flange head bolt and M10
flange nut hand tight. Fit upper fixing on alternator to nose bracket outer end using the 13.5mm spacer
and M8 x 55 flange head bolt. This defines the position of the nose bracket. Tighten bracket to engine
mounting plinth to 50 Nm. Remove alternator top bolt to allow supercharger to be fitted.
13. Prepare supercharger: Clean mating faces of supercharger and outlet adaptor using Betaclean 3900. Fit
'O' ring into groove in outlet adaptor and fit to supercharger using 6 off M8 x 25 setscrews with Permabond
A130. On the fixing located inside the adaptor, Permabond should be applied over the entire thread length.
Orientate the adaptor with the outlet pointing towards the rear of the car when fitted. Torque tighten all
fixings to 25 Nm.
Clean mating faces of outlet adaptor and outlet elbow using Betaclean 3900. Fit 'O' ring into groove in
outlet adaptor face. Fit outlet elbow to point to LH side of car using 4 off M8 x 25 setscrews with a pipe
clip bracket secured by both rearmost fixings. Tighten to 25 Nm. Fit double pipe clip into front side of
each of the two brackets.
14. Fit M8 stud B111E6081S into RH top (as viewed on face) fixing position in supercharger inlet flange. Clean
mating face on supercharger and inlet adaptor using Betaclean 3900. Fit 'O' ring into groove in adaptor
face and fit adaptor to supercharger using 2 off M8 x 30 flange head bolts in top positions and M8 flange
nut on stud - all 25 Nm. Disregard 4th position at this stage.
15. Fit original throttle body isolator to inlet adaptor using the clockwise choice of fitting position, with original
fixings tightened to 10 Nm. Fit the original throttle body to the isolator using original fixings tightened to
10 Nm.
16. Mount supercharger: With the pulley removed from the supercharger, slide the nose into the nose bracket
until hard against the machined step. Support to the inlet manifold sliding bushes using M10 x 50 flange
head bolts and Permabond A130, but do not tighten. Tighten the nose bracket socket head pinch bolt to
25 Nm.
17. Loosley fit the supercharger support strut between the inlet adaptor (M8 x 55 bolt with A130) and the clutch
slave cylinder new fixings (M8 x 25 with A130). Tighten the three support strut bolts to 25 Nm. Carefully
tighten the two M10 x 50 flange head bolts to pull in the two spacers evenly to clamp against the super-
charger.
18. Refit the alternator upper bolt and spacer and tighten to 25 Nm. Tighten the lower bolt to 25 Nm.
19. Fit the pulley to the supercharger with the longer boss towards the 'charger. Fit the nut onto the shaft, and
