    E30 swapping from an M50 to an S50/52?

    Just wondering if there is less work/headache involved swapping an S50/52 into an E30 that already has an M50 swap?

    wrong section...

    24v section will know more, but here's a rough idea.
    m50->S50 = maybe a different ECU
    m50->s52 = converting to OBD1 or making OBD2 work

        No, it's simply swapping a longblock and DME. One other thing you may have to do is tap the head for a second coolant temp sender.
