Before proceeding with the installation, it is important to know that to validate the 2 year, 100K warranty on your new J/R supercharger, you must completely fill out the Moss Motors / Jackson Racing warranty card that comes in every kit, including serial number which is on a small white ‘bar code’ label on the body of the supercharger. Write down all of the numbers which appear on that label in the appropriate space on the warranty card. Be certain to do this now because once your supercharger is installed, it may be almost impossible to retrieve that serial number.
Disconnect your Miata’s battery.
Release the Air mass sensor harness 5-pin connector by pressing the locking tab on its clip. Remove the stock Air mass sensor from the air box by removing the two 10mm headed retaining bolts and then remove the Air Temperature sensor with its rubber mounting grommet from the Air filter box. And finally remove the air filter assembly complete with intake snorkel; these parts will not be reused. Move the Air mass sensor to a safe place on a worktable.
Remove the molded rubber elbow and hard plastic tube that lead from the throttle body to the Air mass sensor. If you have cruise control, you will also have to remove the vacuum line from the intake manifold nipple and from the points where it attaches to the hard plastic intake tube. Remove the cruise control vacuum line from the cruise actuator as well and save it for use in step #4.4 below.
Remove the chrome crankcase vent pipe that is attached to the front of the cam cover and the rubber hose that leads into the cam cover (see figure 1.4). These can be stored away. However, find the small restrictor inside the rubber hose that ran from the chrome tubing to the Mazda plastic crossover/intake tube. If you do not have a restrictor in your hose there is one supplied in the hose bag. It can be felt as a lump in the straight section of the hose near the chrome tube end. Persuade it out by gently clamping the hose with a pair of pliers just behind the lump. Save the restrictor for step #7.8. Reinstall the chrome bolts that held the tubing in place. Store the chrome tube and Mazda hoses.
You can do this entire procedure without loosing too much coolant; there is no need to drain your cooling system. In the upcoming step you will be removing the throttle body and Idle Control Solenoid (ICS) valve. If you remove the small coolant hoses that run to the ICS valve (which is mounted under your throttle), you can drain the excess coolant into a coffee can or such. Rest the can on the steering rack down in front of the engine and aim the hoses into the can as they drain. Once the flow stops, you can remove the throttle body without making a mess.
