if the honda is stock deffinently the fiat

I want to fix it up add some more Horsepower and turbo and some other stuff. Want to race with one of them.

99 00 HONDA CIVIC SI JDM SPORTS B-SERIES TURBO KIT for like $959.98 i was wondering if its worth it i just want something that i can start out with and build from later.

you asked a similar question with reguards to a super charger, the answers are the same, your not looking at anything else, you also dont specify if its auto or manual (i work for honda and ive never seen a manual accord in that style) No honda automatic transmission can handle that kind of increase, especially without alot of custom work, ive only seen one, and i repeat, one, 5 speed accord v6 and thats cuz the kid did custom work, those are luxury not race cars, your motor may be able to handle it, but your tranny wont
but to flat out answer your question, turbos offer a gain anywhere from 50HP and up with proper tuning, fuel system, engine management
