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. The Supercharger kit mounted on a B16A1 Engine.
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. Remove the plastic wiring clip from the intake bracket. Bend down these metal wire holders to clear supercharger intake.
Oil system The oil return drain plug is installed in the block. 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. Install the two flat offset plates using the stock bolts. Grind off some material from the tensioner fixing bracket to make it clear the stock bolt heads. Reinstall the tensioner fixing bracket using the two M10 bolts 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.
