As a current owner of a crossfire and a previous owner of an S2000 its a close call. You will have him from the initial start but when he hits his VTec WATCH out. Thos S2000s though they have low end torque they can rev forever picking up incredible speed quickly so it would be a close call let us know. The S2000 sort of dogs out from 110 onward (real slow speed increments) and thats where the XFire might have his lead.
