yah i wouldnt suggest doing anything as far as the engine goes besides basic maintainance, get a radio, get some wheel locks if u want, when u change engines more than likely u wont be able to change over any engine mods anyways so isnt worth it, if u want start looking into better shocks and struts, to handle the extra weight of a new engine as well as urs are probably shot with that much mileage, congrats crx's are great cars, hope u enjoy ur new pocket rocket
