Advice for New IM for B20 Swapped into '90 DA9 (OBD0)

If I get new ecu (chipped p28 with a b20 map loaded on it) and OBD1 conversion harness…

  1. can I get rid of my old IM from original B18A1 and put in a Skunk2 or other aftermarket IM fit for the B20?

  2. If so will the the new IM come with FITV and IAC? (I hope so!)
    Thx

Yea of course, theres no FITV on 99% of aftermarket manifolds tho (the ecu does all that now), but thell have the IACV to take care of your idle.

Should be good to go!
