well like the saying goes "you can put any motor in any car for the right price." and with corss breeding were talking $$$

as for z6 thats proably not a good idea seeing as your running a 97 civic or "ek" which runs a d16y8 motor which is obd2 and not obd1 like the z6. SO, if you buy a d16y8 which comes out of the EX civics it will drop right in there for the least ammount of money. you can use just about everything your car has already tranny, axels etc.
