88-91 sedan Civic dx

[nitebluesky]

I was thinking of purchasing an civic ef sedan dx. From what I have read that the 1988 model civic has a different transmission than 89 to 91 teeth. Anyways, I was thinking of putting a HF transmission and than in the near future a D15z1 motor. I would prefer an 1988 since its lightest of all ef sedans. My goal is to get better mpg, but i don't want a crx or hb. I need a trunk. Has any on here done such a thing? if so tell or send me a link.
