If you compare curb weight vs curb weight the RSX weighs a little less. But it also puts more power to the ground in stock form the RSX makes almost 10hp more than the Prelude but 10-12ft lbs of tq less. I have seen a stock type s beat a 99/00 lude with an AEM SRI if that gives you any reference. I would say TYPE S, it has more raw potential than just about any Honda/Acura ever made.
