Well the S2k is really not a tuner's car...you can do suspension, brake work, wheels and tires...but power wise...it's not going to get over 1000hp like a Skyline or Supra will...then again...it's a 30k car...not a 45k-50k like the Skyline and Supra were in their respective markets
Upsides of the S2k are it handles very well...it's RWD...relatively light (2800 lbs) by car standards today...and it looks good...
But I cant wait for a coupe version...lol
