i have a 93 civic ex sedan, and i am having a lot of problems with the uninspired D15 engine. i plan on selling the car in the next 3-4 months, but for the meantime, i want something with a little more balls. i really dont want to spend a lot of money, and i was thinkin of grabbing a JDM dohc zc engine. i dont know what kind of problems there might be with the install, except that the zc is non-OBD, and my car is OBD I. any help you guys can give would be appreciated.
