If you do it, your car will triple in resale value. Sad but true.

From what I've read, Civics are much more of a pain to convert then some other cars. I don't think the firewall of a Civic is symetrical, like RX-7's (and 240SX's, IIRC.) If the firewall isn't the same for US and Japanese cars, you're in for some trouble.

If this car is supposed to be your daily driver, forget about it.
