Potential sentra project

guys im looking at building a drag/track car out of an older sentra, i know the suspension and power are good for track use on the new spec v's but im not too familiar with the older bodies and engines (except the sr20.....duh) could you guys help me choose a good year for the chassis, i think i have engine work under control but id like to get a good start on the body so i dont have too much more work to add. thanks
