2015 SI HP Gains

[Josh Gustafson]

I just picked up a 2015 Honda Civic SI and I want maximize performance without turbo/supercharging. What are some things I can do to get to around 235-240hp. I have around a 2000$ budget! I also don't want to void the whole warranty!

Exclamation marks!


You can't figure out something better to do with 2k? You modify the cup holder on that thing and you might void the warranty, why risk it?

Supercharger actually is probably the bester route, but they're out of your budget. Kraftwerks makes a supercharger kit, which is completely bolt on, but its $4200. You can take it off to avoid messing with warranty

That's a low power goal but easily achievable...Hondata flashpro, cold air intake, down pipe, and exhaust. Total will be right around your budget.

I'm with him on this. The 8th and 9th gen Si's respond extremely well to bolt ons with Flashpro. The great thing about it is you can change tunes on the fly, and it makes getting your car tuned a lot easier.

Best bet here - reliable and will get you that extra 30-40hp you're looking for.
