Push Your Limits

Nitrous oxide. It can put you at ease when you're at the dentist, and is good for up to 200 hp at the dragstrip. The last of these is accomplished because nitrous oxide lowers intake air temperature, increases oxygen content of the intake charge, and increases the rate at which combustion occurs in the engine's cylinders. Let's simplify that: Cold Air plus More Oxygen equals Your Car Kicks More Ass at the Touch of a Button.

Nitrous Oxide Systems has known this for years and has started to take notice of the increase in nitrous oxide usage by the import racing market. From homemade nitrous cheater kits to full blown-out pro drag setups, everybody's using it. So why not develop a properly designed kit for every level of enthusiast? The kit that NOS came up with is a nitrous plate injector system that not only delivers maximum performance, but utilizes EDM technology to obtain a more infinite, consistent mist while being fully adjustable to produce from 75 to 200 extra horsepower.

As of now, the NOS nitrous plate injector system is available for the '94-'97 Acura Integras (1.8L VTEC) and '93-'97 Honda Preludes (2.2L VTEC), with the sole intention of being engineered for vehicles with either mild or extreme engine modifications for race usage only. The horsepower and torque increases will differ depending on engine tuning and the extent of modifications, and it is recommended that you strengthen the bottom end should you decide to up the horsepower.

St. Andre's invited us down to its domain to check out the installation process on a '95 Integra GS-R. Keep in mind that this car already had a dry manifold nitrous kit, so installation on your vehicle may be slightly different. Nitrous is not something to be taken lightly. If you've never dealt with it before, seek out a professional shop for help on the install.

First, allow the engine to cool completely, then disconnect the battery and drain the engine coolant from the cylinder block. Remove the air filter and engine air intake hose assembly.

Before you install the NOS injector plate on the intake manifold studs, remove all the old gasket material from the intake manifold, secondary butterfly plate, and intake manifold plenum with the set provided by NOS. Install the NOS injector plate onto the intake manifold studs. Fit a second intake manifold gasket, then the secondary butterfly plate. Finally, install the third intake gasket and then the intake manifold plenum.

Be sure to test-fit the solenoid brackets on a location where you can mount the solenoid. A spot against the firewall is generally best.

Attach both the nitrous and fuel solenoids to the solenoid mounting brackets, then select a mounting location for the solenoid assembly. Make sure that the assemblies and lines do not interfere with engine accessories or body parts and that the hoses can reach the injector plate inlet ports without being stretched or kinked. Mount the solenoid assembly securely.

Mount the throttle microswitch on the throttle body, which is activated by throttle linkage movement. It should trigger at wide-open throttle. Ensure the throttle and switch reach the activation point with the accelerator pedal by the clicking sound it produces.

The result should look similar to this. If it does, move on to the nitrous toggle switch installation and bottle positioning. If it doesn’t, you did something wrong. Try again.

Install the NOS arming toggle switch in the vehicle interior. Push the throttle wide open while the engine is off, making sure that a clicking noise is produced. If no noise is heard, it’s not cycling correctly and you should check all wiring connections

At this point, you will need to install the nitrous bottle. Since we will be using funny gas in our daily drivers only at the track, we need to make sure that the bottle is installed in the trunk with a Racer Safety Blow Down Tube. Use the assembled bottle/bracket/ blow-down tube unit asa pattern to mark the holes for drilling.
