Actually for your car a Turbo is the way to go. A good kit by either Greddy or Turbonetics is the way to go. They have all the necessary items you will need including the fuel manangement. As for horsepower you will gain about 100-125 hp and 60-80 ft lbs of torque. DO NOT BUY those cheap kits that dont have your fuel management, as they seem like a good deal to begin with, you will wind up paying more in the long run trying to get the car tuned. Expect to pay around $3,500 for the kit, but a good mechanic can have it on and running in a day.
