I own a 2003 Accord with a K24a4 engine and am looking for advice on mods to boost its power. Can anyone suggest where to start and what upgrades to consider for the future?
Before anyone suggests selling it for a better car, I know it is not exceptional, but it is my first car, and I want to see how much I can improve it. My friends are doing similar projects with their first cars, so getting a new car is not an option.
The only two ways to enhance engine power are to increase the compression ratio or switch to forced induction.
Bolt-on modifications won’t make much of a difference in your automobile because the ECU is designed to operate in a specific manner. The ECU will adjust for the changes to some extent by adjusting the engine’s fuel spray volume, temperature, and/or air volume. You’ll get a check engine light and the ECU will likely run the engine rich to avoid damage if it can’t accurately adjust for the various circumstances.
