1.8l miata port and polished
 

the miata I bought was port and polished and has a k&n intake on it. also i think it has a upgraded exhaust too. Also there are bilstein coil overs on it. To me this car handles so unbelievably good. anyways enough with the small talk, with the upgrades I was wondering how much added horsepower that would add??? becasue i think im going around 7.2 sec 0-60 maybe less.. my car is a 99. Also I just bought a 6 puck clutch and a 8 pound flywheel and was wondering if that was a smart buy?

useless to guess unless you have had the head bench flowed to check the imporvements. even then the improvements are pretty minor with an otherwise stock motor.

puck clutches are a little harder to drive o nthe street because of their on/off characteristics.
