is the sub frame that the motor bolts to in a 97 sunfire gt 2.4l 5 speed the same as the 97 cavalier sedan 2.2l automatic. are they the same and can i just interchange the sub frames without modifiying anything?
As far as i know the two sub frames are exactly the same. You shouldn't need any modifications.
engine cradle might be different as well as your engine mounts and trans mounts. but the frames are not different.
