Well, I am going through a quart a week of oil in my 1991 Civic SI and I am thinking on getting a JDM motor. I like the Hp of the ZC SOHC motor with a almost just drop in installation. I've seen them with just motor for sale. Will my SI tranny fit the ZC engine? If so, is there anything I need to know about the clutch, since I'll be replacing it while its out along with water pump, timing belt, and get a light crank pulley.
