E30 swapping from an M50 to an S50/52?

[99em1]

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

Oh sorry, didn't realize it was the wrong section.

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.
