Default OBD1 Engine swap - which computer?

1995 ti, going to be swapping in an i6. I have a bunch of parts, including an aluminium z3 2.8 block & crank and a complete M50. I was thinking I'd just use the 2.8 block and the rest of the M50, with the 325 ecu, but I realized I could use the 2.8 crank instead with the M50 head.

If I did the 2.8 block and crank, which OBD1 BMW ecu should I use? 325? M3? I'd like this beastie to be theoretically smog legal when I get done...
