I have recently but a 88 - 91 zc motor in my 94 civic dx. was wondering what recomendations you have for the motor itself and what trouble i am gonna have with it in the time ahead. Also i have my stock tranny hooked up. What is a recomendation for the zc with a civic tranny? Also does anyone know a site for civic tranny codes cuz i want to see if my tranny is dx. Couple fo people said it looked like an ex. just want to be sure.
