Ford Gemini Twin Plate Systems Electronic Fuel Injected Installation
Congratulations on the purchase of your Nitrous Express Ford Plate system. You have chosen the finest nitrous system ever. Nitrous Express utilizes only the highest quality components designed for the use of liquid nitrous oxide. To properly utilize these specially designed components and obtain the trouble-free operation that this system is capable of producing, it is extremely important that you read all instructions carefully. Pay special attention to the important notes at the end of the installation steps and the tuning tips listed at the back of this instruction sheet.
NOTE: All NX EFI Gemini Twin Systems come with dual stage spray bars pre-installed at the factory. To up-grade your standard single stage system contact your local NX dealer and ask for PN NX200DS.
The NX GeminiTwin EFI system is designed to operate with stock fuel pumps and no timing retards up to the 150 horsepower setting. On all settings above 150 horsepower the following precautions should be observed:
A. An extra capacity aftermarket fuel pump must be used. 250LPM Minimum
B. High octane race type fuel must be used to prevent detonation.
C. Increased strength internal engine components and high performance head gaskets may be required.
D. Depending on compression and fuel quality timing retard may be necessary to prevent detonation. If you have an aftermarket ECU chip that advances the stock timing, detonation could be a problem. These chips can still be retained if higher octane fuel or NX Power Booster (PN # 16000) fuel additive is used. On Dual Stage systems an aftermarket, high capacity fuel pump must be installed. Depending on your combination and level of nitrous boost, timing retard may also be required.
To insure proper system assembly and operation, carefully read the following installation procedures thoroughly before beginning. Use NX thread sealer on all pipe thread connections, DO NOT use any sealer on flare connections, hose, or bottle connections. Use no other sealing compounds or Teflon tape. All threads must be clean and dry, apply only enough sealer to wet the threads, too little is better than too much. Excessive tightening of parts is not necessary, snug is enough. If it is necessary to remove a fitting installed with the red NX sealer heat must be applied to release the sealing agent.
NOTE: Due to shipping restrictions all NX nitrous bottles arrive empty. Before beginning the installation the N2O bottle should be filled by a NX accredited filling station. For filling station locations log on to www.nitrousexpress.com
Before starting any installation procedures carefully disconnect the vehicle negative battery cable. If there is any question about this operation consult the vehicle owners manual.
