I have bought m20b25 engine that came out of 1989 saloon. Didn't come with ecu, looking for some advice on what ecu I need to get? Thanks

You can see the relevant ECUs here
https://www.e30zone.net/e30wiki/index.php?title=ECU. Bear in mind that the only difference between the 320 and 325 ECU is the chip, so a 320 ECU with a 325 chip (available from speedtouch on the zone) will be fine.
