Compare Honda Civic Si Engine HP & Torque for All Trims

How to increase your Honda Civic Si horsepower?

I think every one of us at least once in our lives has wondered if their car can go faster. And the truth is, yes, it can. You can increase the power of your Honda Civic Si yourself - installing various modifications can give you a boost in power. It all depends on your starting budget and how much money you're willing to pour under the hood of your iron horse.

We've prepared for you a list of different modifications for different budgets that will somehow make your Honda Civic Si roar more aggressively.

$0-$100 Modifications

With a budget of $100, the modifications that can be made are limited. However, some budget-friendly modifications that can help improve the car's power include:

• Air filter upgrade: A high-performance air filter can improve airflow to the engine and increase horsepower, often for under $50.
• Spark plug upgrade: Upgrading to high-performance spark plugs can improve combustion efficiency and increase power, often for under $50.
• Performance programmer. An engine performance programmer (also known as an engine tuner or performance chip) is an electronic device that plugs into a car's diagnostic port and modifies the engine control unit (ECU) settings to improve engine performance. an engine performance programmer can increase horsepower by optimizing the engine's fuel and ignition parameters, enhancing throttle response, and removing factory restrictions.
• ECU tuning: A simple ECU (Engine Control Unit) remap can be a cost-effective way to unlock additional power from the engine, with prices starting at around $100.
• Installing throttle body spacer. The theory behind the throttle body spacer is that the increased distance between the throttle plate and the intake manifold creates a larger plenum volume, which allows for more air to enter the engine. This increased airflow is believed to provide a boost in horsepower and torque, particularly in the mid to high RPM range.
  The cost of a throttle body spacer can vary depending on the make and model of the car, as well as the material and design of the spacer. In general, prices can range from around $50 to $150.
• Regular maintenance of the car. There is no specific product in this category that we can recommend to you. However, it is important to remember that the power of your Honda Civic Si is directly related to how well you take care of it. If there is a malfunction in your car, it will prevent you from gaining speed and enjoying the ride. So our advice is to take good care of your Honda Civic Si: change oil, filters, spark plugs in time, make sure everything is in order, there is no visible damage anywhere, and then the car will give you all the power it has under the hood.

$101-$500 Modifications

With a budget of $500, more modifications become available. Here are some suggestions:

• Cold air intake: A cold air intake system can improve airflow to the engine and increase power, often for around $200.
• Exhaust system upgrade: Upgrading to a performance exhaust system can improve exhaust flow and increase horsepower, with prices starting at around $300.
• ECU tuning: A more comprehensive ECU remap that includes adjustments to fuel and ignition timing can be a more effective way to unlock additional power, with prices starting at around $300.

$501+ Modifications

With an unlimited budget, the sky is the limit in terms of modifications that can be made to improve a Honda Civic Si power. Here are a few suggestions:

• Supercharger or turbocharger: Adding a supercharger or turbocharger to the engine can significantly increase power output, often by 50% or more. Prices for these upgrades can range from several thousand to tens of thousands of dollars, depending on the complexity and scope of the installation.
• Engine swap: Replacing the engine with a more powerful one, such as a larger displacement or higher-output version, can be an effective way to increase power. Prices for engine swaps can vary widely depending on the make and model of the car and the complexity of the installation.
• Nitrous oxide injection: Nitrous oxide injection can provide a temporary boost in power, with prices starting at around $1,000 for a basic system.
