Negative. The Stock 00-03' S2000 use a 4.11 Final Gear while the RWD Skyline R33 use a 4:10. (I possibly said that backwards). The difficult part is you need to have a customer driveshaft and axles to get them to work.
Sean mentioned a shop in Northern VA that is working on designing this kit. However at this time there is only one shop Diff Technics who offers this as a Full Kit. Aluminum Driveshaft, Differential & 1000hp Axles!
