Is it worth it???

Im caught in a dilema. I can either get the basic parts for my accord (rims,strut/sway bars,intake,headers,exhaust,pulleys,ground effects) that wont really make it alot more powerful --its the 150HP manual 4door....... or I could use the money to get s street bike. I dont really want to spend a total of 10K$ (including a new turbo) for a car that wont handle as well as a coupe would and definately wont be as fast as a coupe. So what would you guys do, use the money for the accord or use it for a street bike. They bike will probably be a Yamaha R6.
