Before you start installation
Take some engine bay pictures for later reference. Make a special drawing of all the coolant hoses going to the different parts of the stock intake, you will need this later on. The same goes for the vacuum hoses to the different parts of the intake. Mark the electrical connectors to the MAP sensor and TPS sensor. You will need this later on. Drain the engine coolant.

Removal of parts
Remove factory airbox and plastic intake hose.
Remove the throttle cable from the intake.
Remove all air and water hoses from the intake.
Remove all electrical connectors from the intake.
Remove the fuel pressure line and fuel return line from the fuel rail.
Remove the two bolts underneath the intake (intake bracket).
Remove all nuts holding the intake.
You should now be able to remove the intake.

Unscrew the stock plug. Install the custom fitting using the stock sealing washer. The pressurized oil can be taken from the oil pressure sensor. Remove the sensor and fit a suitable fitting/hose/T-piece etc. in the same manner as a turbo kit uses. Another alternative is to use an adapter plate between the engine block and oil filter which has an oil outlet. Install a new oil filter. Alternator drive system Remove the alternator drive belt. Remove the alternator. Remove the alternator pulley. Replace it with the twin pulley. Remove the alternator mounting bracket. Remove the alternator mounting bracket collar (ring-shaped part that the alternator mount bolt passes through).

Install the bracket collar in the new bracket. Install the new bracket (with the bracket collar installed). Install the alternator in the new bracket.
Remove the stock tensioner fixing bracket. Now you shall try if the M8 fixing bolt fits through the alternator and the tensioner fixing bracket. If it doesn’t fit you must adjust the position of the two offset plates until the M8 fixing bolt fits. Slip the supercharger belt on the inner part of the twin pulley. Just let it hang there until further. Now install the stock alternator belt on the outer part of the twin pulley and the crank pulley and tension as usual. Tighten the alternator nuts as usual.

The supercharger package comes preassembled: Intake/supercharger/intercooler/throttle adapter. Install a new intake gasket and then install the supercharger package. Make sure the electrical wiring (to injectors etc) ends up on top of the intake runners. Tighten the intake nuts. Two of the bottom four nuts are tricky to reach, but it is possible! The nuts can be put in place by hand from above through the space between the runners.
Wrench with 30cm extension (that can angle a bit). Two of the bottom four nuts are tricky to reach, but it is possible! The nuts can be put in place by hand from above through the space between the runners. Wrench with 30cm extension (that can angle a bit). Install the two M8 pin bolts through the bracket holes by hand. Install M8 nuts with washers on the pin bolts. Tighten by hand only for now. Tighten the bracket bolts by hand only first. Make sure the bracket fits properly to the intake (two M8 pin-bolts with nuts) and the two engine-block bolts. Tighten these nuts and bolts by hand a little bit at a time. When the bracket is firm both to the intake and the engine block all bolts and nuts can be tightened properly.

Install the fuel injectors and the fuel rail. Connect the fuel lines to the fuel rail. Connect the electrical connectors to the injectors. Note that some injector connectors must be angled 180 degrees to make them clear the fuel rail mounting bolts. Connect the electrical connector to the air temp sensor. Throttle install Remove the two electrical connectors on the distributor. Also remove the metal bracket holding these connectors. The two connectors are repositioned lower down to make room for the throttle body. Secure the connectors with straps. Remove the throttle body from your stock intake. Remove the four M8 pin-bolts from the stock intake and install them on the supercharger package. Install the throttle body on the throttle adapter using a suitable gasket. Remove the metal bracket that holds the throttle cable and the clutch cable (mounted on the shock pillar) if it interferes with the supercharger drive pulley. The throttle cable is mounted to a custom bracket which is bolted to the throttle adapter. The bracket is easily made of a piece of 3mm steel plate. The hole for the throttle cable is 8mm and the cut-out is 6mm wide.The throttle cable can be reused on some cars, but on others it will be too short. In this case get a longer one for another Honda car.

Your local Honda dealer can help you with this. After the throttle cable is bolted in place you will need to adjust the length of the wire inside to suit your car. Cut off the stock wire stopper (the one that is inside the car at the pedal) and install a screw stopper (you can buy this at a bicycle store). Tighten up the wire and secure the screw stop. Cut off the excess wire. Make sure the throttle opens and closes freely and fully. Remove the throttle body from your stock intake.
