for one, you had an rx-7 and you want a lude???? i hope it wasnt the last gen rx-7 :-) secondly..... unless you like the body styles of the 3rd gen ludes which are 91' down to the late 80's in the years, or want to do a swap, then id look for a 4th gen (92-96) or 5th gen (97-01)... as far as body style goes people will argue which is better all day long, it only matters which one YOU like better.... the 4th gens have the S model, which is I believe 127hp and 132ibs of torque, the SI model, which is 160hp, and the "vtec" model which is 190hp and the engine code is h22a1. For the 5th gens, there is either the base model, or the SH model. The SH model is nice, it has the ATTS (active torque transfer system) for steering, 5 spoke star rims, painted side skirts, the engine and specs on both are the same 200HP and 156ibs of torque I believe. The base model is not like buying a civic dx or something, as it is equipped with power everything, and the same motor as the SH... it would really just depend on which one you wanted/found first, and the SH will be a little more pricey. The SH is only 5spd, and the base comes with either 5spd or a SS auto tranny (which had some problems from the factory)...lemme know if you want to know anything else bout them, i dont know too much about the older gens though....
