Honda/Acura Nitrous Oxide Injection System Manual Installation Instructions

Honda/Acura Nitrous Oxide Injection System Manual Installation Instructions - System Requirements When used correctly, Kit Number 08201NOS is designed to work with stock Honda internal engine and driveline components. The jet combination in this kit generates a 50 HP gain at the flywheel. If the jetting is increased over 50 HP, it is advised to upgrade the fuel delivery system, retard timing, and use a colder spark plug to ensure safe operation. Higher HP levels also require additional modifications, such as forged pistons.

Chapter 2 Kit Installation 2.1 Bottle Mounting Instructions Accurate calibration of your NOS nitrous system depends on the bottle remaining at a stable temperature. Mount the bottle away from heat sources, such as the engine compartment or exhaust system, and away from windows, where the bottle is exposed to direct sunlight. 2.2 Bottle Orientation Bottle placement is critical to the performance of your NOS nitrous system. It is important to understand how the bottle valve and siphon tube are assembled to properly orient the bottle in your vehicle and ensure that it picks up liquid nitrous while undergoing acceleration. All nitrous bottles are assembled so that the bottom of the siphon tube is at the bottom of the bottle and opposite the bottle label (Figure 2). Whenever the bottle is mounted in a lay-down position, the valve handle must be towards the front of the vehicle with the label facing up (Figure 3A).

2.3 Bottle Installation Before mounting a nitrous bottle in a racing vehicle intended for use in sanctioned events, check with the sanctioning association for any rules regarding this subject. Most associations require the bottle to be mounted within the confines of the safety roll cage with the safety pressure relief cap vented away from the driver’s compartment. This feature is included in the 08201NOS kit. NOTE: Numbers in parentheses ( ) refer to the parts list (Table 1). 1. Install the bottle nut adapter (1) and washer (2) on the nitrous bottle (3), and tighten securely. 2. Slip the bottle mounting brackets (4 & 5) onto the nitrous bottle, as shown in Figure 3E. 3. Locate the bottle assembly in the desired mounting location, ensuring that the location will provide easy access to the bottle valve, hose connection, bracket clamp bolts to facilitate bottle changing and through hole of the blowdown tube. 4. Use the assembled bottle/bracket unit as a pattern to mark for hole drilling. Drill four 11/32″ holes in the mounting surface for the bottle bracket bolts. Make sure the holes are in a position that does not damage other components.

Acura RSX Heated Mirror Installation Instructions

Acura RSX Heated Mirror Installation Instructions - Dissassembly: OK so let’s get started: It’s best if you have the Helms manual but you can do without it if you have done other similar installs on this or other cars. 2. Remove the door panel: a. You will need to remove the door handle assembly. Pop off the plastic cover behind the handle and you will find 2 screws.

Once you undo the screws you can pull the assembly out. Remove the lock cable from the door handle. b. Then unplug the connector. There is one more screw you will need to find once you remove the handle assembly. Remove this screw too. Every time I did this, the screw fell into the plastic door panel handle cavity so I had to retrieve this screw after the door panel came off by turning the panel upside down. Next remove the 2 screws under the armrest. c. Remove the black plastic trim piece on the inside of the door opposite the mirror. Roll the window down and pop the piece up and inward using a little upward pressure. A screwdriver taped so it would not mark or scratch anything works best. d. Now you are ready to remove the door panel.

To do this it is best to use a door trim tool. You can pick one up at your local auto store. This is used to remove the 8 clips that hold the plastic panel to the sheet metal. e. In order to completely remove the panel, unplug the connector for the window switch. 3. Remove the mirror assembly: Note it is possible to skip this step and work on the mirror while attached to the car a. Unscrew the three 8 mm nuts holding the mirror to the inside of the window. b. Unplug the mirror connector and take the mirror assembly totally off 4. Remove the glass mirror element from the assembly: a. Gently push the top of the mirror in as far as it will go. This will create a small space between the bottom of the mirror and the housing. Use mostly just your fingers for this.

 I also used a hair dryer and an assistant to heat the mirror (don’t over do it) while pulling the mirror with the black plastic holder from the white plastic actuator. I did use a screwdriver here very delicately to help separate the two items. This was easily accomplished without breaking the old mirror.
