there are More parts for the S14 chassis out there than the B13-14-15 combined.... I dunno how can U make that assumption. Why is the SE-R soo quick...its the whole power train...every gear is matched for max power and engine spools up RPMs QUICK like some V8 don't even do. Try to rev a 140HP Tiburon and see how responsive that engine is. Mike Jez Ricer for life.
