I still don't see how the 200sx SE-R is a full 167lbs heavier than the 200sx SE. If anything, the SR20 is lighter or equals out. The SE and SE-R have the same options except for the wheels, side skirts, and rear discs, that's not a 167lb difference. IIRC, in the B13 line, the E was the lightest, then the SE-R, the XE, and then the SE being the heaviest. The only reason the E was lighter was b/c it had nothing on it, but the SE-R was lighter than any of the other 1.6s.
