If you’re looking to increase your Nissan’s engine performance, you probably have about a thousand questions. You also might think that increasing the performance is an expensive and tedious task. While it very well might be, there are quite a few ways to go about the process, and some of them aren’t as expensive and tedious as you may imagine. You don’t even have to be THAT car-savvy or even take your Nissan to a mechanic. Either way, it’s important you understand your engine first, then know what your options are.
Understanding How Your Engine Works
When you want to add more power to the engine, it’s important to understand how the engine creates the power that propels your Nissan forward. In basic terms, the engine burns fuel with the help of air, and the power comes from the controlled explosions that occur in the combustion chamber. So, it’s quite simple really – more fuel and cold air in and more exhaust out result in more horsepower and torque. That being said, even some things that may seem trivial to most people can play a huge role in how your engine performs. As a result, some products make it extremely easy to get more torque and horsepower, no matter whether you’re driving a sedan, sports car or ute. Here are the most popular ones:
Nissan Electronic Throttle Control and Injectors
The throttle is responsible for sending air into the engine, whereas injectors are responsible for sending fuel into the cylinders. Clogged fuel injectors and a stuck throttle can rob you of power and torque. If you want to increase the torque of your Nissan, you’ll need to dabble with the fuel and air supply systems.
However, even if everything is okay with your throttle, the factory settings in the ECU make it respond a certain way when you press the accelerator pedal, in order to ensure smooth acceleration and reasonable fuel economy. An aftermarket Nissan electronic throttle controller can help you replace these factory settings with custom settings that don’t care about fuel economy, but help you get more torque out instead. In other words, your throttle will be more responsive, allowing for faster acceleration.
The fuel injectors, on the other hand, need to stay clean. In order to be clean for as long as possible, you should use quality fuel. If you suspect your fuel injectors are clogged or dirty, consider using fuel injector cleaners that remove carbon deposits from the injectors, lines and fuel tank. If you want to burn more fuel to get more power, you should consider aftermarket fuel lines larger in diameter.
That being said, you have to make sure the fuel injector and throttle provide the optimum amount of fuel to air ratio if you want to get optimum amounts of power. If you feed your engine lots of fuel but not enough air, or vice versa, you won’t get the desired performance increase.
It doesn’t matter how much fuel and air goes to your engine, if the cylinders aren’t provided with the necessary spark, your engine won’t perform at its best. For that reason, you need your ignition system to carefully time the spark plugs in order to ensure optimum performance. Spark mistiming can lead to many issues, and if you’re experiencing any, you should rush to your mechanic. Most ignition systems won’t give you an error code without a problem, but even minor problems can rob your engine of power.
If your engine gets more air than fuel, you’ll need a higher voltage to trigger the ignition of sparks. To get this energy, you’ll need an amplifier in the ignition system. The type of amplifier you should get will depend on whether you have a coil-on-plug system or a distributor coil. Single-channel amplifiers and a set of new coils can help the distributor system. On the other hand, a multichannel ignition amplifier will help the coil-on-plug system.
Cold Air Intake
A cold air intake does what its name implies it does – provide your engine with cooler air. In case you didn’t know, cooler air is richer in oxygen, helping the combustion process by burning fuel more efficiently. As a result, you get more power. When installing a new cold air intake system, you’ll get a new air filter as well. The filter may look weird, and the reason for that is its relatively larger size. Besides that, cold air intake systems can smoothen out the air flows into the engine. Curves can cause air to slow down and swirl, reducing flow. If you remove the convolutions in the pipes, the system will send air faster to the engine. This is the most affordable upgrade you can get to achieve significant results, and it’s one of the most popular aftermarket modifications. Once you install an aftermarket cold air intake, make sure to maintain it by keeping the filter clean.
