Does anyone know if the E36 body will support a Z3 engine which I was told is the same as the M3 engine? I don't know anything about th Z engine, if it is the same or not as the M3 e36 engine. Thanks.

what year z3? does it have the s52 or s54? if it is the s52, it will fit nicely in your e36 chasis. same engine.

Z3's up to 2001 had s52's. 2001 and on had s54's.
My cars engine is out of a 99 mroadster (z3m)

It is an S52, so it seems everything should be good. I am told it has 51K for miles. How do you verify, or is it that important?

lets make this absolutely clear that an ///MZ3 coupe had the ///M motors as mentioned above, but there were Z3's that did not get ///M motors, of course.

Yeh, the motor which I am thinking about getting is from an ///MZ3. I want to make sure that this engine is the same as in the M3 E36.

yeah same one. you might have to buy the aluminum e36 engine mounts though.

What year E36 is it. If your going to go with the ZM3 (S52) motor it should be a 96 and up E36, its just a matter of swapping motors out. If its a 95 and under E36 you'd have to do an OBD1 conversion to the S52.

you dont have to go obd1, i have seen plenty of people convert to obd2, but going to obd1 is alot easier.
