If you're looking for serious acceleration gains without the complexity or cost of forced induction, nitrous systems in Canada remain one of the most effective power upgrades available. At TooFast Auto Parts, we carry complete EFI nitrous kits from Nitrous Express (NX) engineered for reliability, safety, and repeatable horsepower on demand.
From weekend street builds to dedicated drag cars, nitrous oxide injection delivers instant power exactly when you need it. With modern EFI control, proper tuning, and quality components, nitrous systems are safer, more predictable, and more powerful than ever.
What Are Nitrous Systems and Why Do They Matter?
Nitrous oxide systems work by injecting nitrous gas along with the appropriate amount of additional fuel into the intake stream or combustion chamber. Nitrous oxide contains more oxygen than atmospheric air, allowing the engine to burn more fuel during combustion and generate a substantial increase in horsepower.
Unlike turbochargers or superchargers, nitrous only adds power when activated, which makes it highly efficient and easy to control.
Key benefits include:
-
Instant horsepower at the push of a button
-
Lower cost compared to forced induction
-
Scalable power increases from 35 to 300+ horsepower
-
Compatibility with EFI and carbureted engines
-
Easily disabled or removed for daily driving
When installed and tuned correctly, nitrous systems offer one of the best horsepower-per-dollar upgrades available to Canadian performance enthusiasts.

Why Nitrous Express Systems Make More Power
Nitrous Express has earned its reputation by focusing on flow efficiency and liquid nitrous delivery, not gimmicks. The goal of any nitrous system is simple: keep nitrous in liquid form until it reaches the engine. Liquid nitrous makes more power than gaseous nitrous period.
NX Lightning Bottle Valve Technology
Nitrous Express designs its own Lightning bottle valves, which differ significantly from typical bottle valves used across the industry. Instead of sharp internal turns that cause turbulence and boiling, the NX Lightning valve features a direct flow path with only a single 45-degree turn. This design minimizes turbulence and prevents gaseous bubbles from forming before the nitrous reaches the solenoid.
The Lightning 500 bottle valve is engineered to support up to 2000 horsepower, using a large .625-inch siphon tube and fittings capable of supporting up to a 10AN supply line. CNC-machined from billet aluminum, it is lighter than traditional brass valves while offering superior flow, dual gauge ports, and interchangeable outlet fittings.
The result is cleaner nitrous delivery, easier tuning, and more horsepower per pound of nitrous.
Lightning Series Solenoids: Where Power Is Won or Lost
Solenoids are one of the most critical components in any nitrous system. Nitrous Express Lightning solenoids are engineered to maintain smooth, laminar flow by allowing nitrous and fuel to enter above the seat and exit through the bottom an approach that significantly improves flow compared to traditional designs.
NX nitrous solenoids feature an integrated purge port, allowing purging directly through the solenoid body. This eliminates trapped air pockets between the purge valve and solenoid orifice, ensuring immediate and consistent delivery when the system is activated.
Lightning fuel solenoids also include a fuel bypass port, which allows trapped air to be returned to the tank. This design eliminates the lean spike often seen with inferior systems. CNC-machined aluminum bodies and carbon fiber cans reduce weight while maintaining strength and durability.
NX Nitrous Plates: Precision Distribution and Reliability
Nitrous Express plate systems are CNC-machined from a single piece of 6061 billet aluminum for precise fitment and consistent distribution. Internal passages are designed to provide excellent cylinder-to-cylinder balance, which is critical for both horsepower and engine safety.
Unlike older spray-bar designs that can sag, restrict airflow, or crack over time, NX plate systems feature no spray bars at all. This ensures unobstructed airflow, reliable operation, and consistent performance under repeated use.

Installation and Fitment Process
Installing a nitrous system typically takes 4–6 hours, depending on vehicle configuration and experience level. The process includes mounting the bottle, routing braided lines, installing solenoids or plates, wiring activation and safety switches, and setting proper jetting.
Proper tuning is critical. Fuel delivery, timing adjustments, and safety features such as wide-open throttle and RPM window switches help ensure consistent performance and engine protection. TooFast provides guidance for both first-time installers and experienced tuners.

FAQs About Nitrous Systems in Canada
1. What is the difference between nitrous oxide and a supercharger?
Nitrous oxide provides an instant power boost by introducing more oxygen and fuel during combustion. Unlike a supercharger, which provides constant power, nitrous only activates when you need it, offering a cost-effective way to boost horsepower without long-term modifications.
2. How much horsepower does a nitrous system add?
Nitrous systems can add anywhere from 35 horsepower on a small single-nozzle setup to 300+ horsepower on advanced, multi-stage systems. The power gain is scalable and can be adjusted by changing the size of the jet or system used.
3. Are nitrous systems street-legal in Canada?
Yes, nitrous systems are legal in Canada as long as they are installed correctly, and all components comply with local regulations. We recommend checking with your local authorities for specific rules in your region.
4. Can I use a nitrous system on a daily driver?
Yes. Nitrous systems can be easily turned on or off, so you can safely use them on a daily driver without impacting reliability or performance. When not in use, the system is dormant and has no effect on regular driving.
5. Will a nitrous system damage my engine?
When installed and tuned properly, nitrous systems are safe and reliable. However, incorrect installation or excessive use without proper tuning can lead to engine damage. TooFast Auto Parts provides guidance to ensure you install and tune your system safely.
