The first post was wrong to answer this we aren't adding HP we are freeing it from the restrictive Intake, Headers, Exhaust that Honda puts on theses cars. A good flowing Catback exhaust 2-5whp 7-10Crank, Header 3-4whp Crank 8HP. So you are looking at 5-9whp which would make your car about .01 tenth of a seconder faster next terms nothing. Unless you get a cam, itb etc etc etc. Going turbo and piercing a turbo kit could cost under $1500-2000 and net you 80+whp Or you can sell your motor for about $600 and get your self a B16, B18 etc swap
