KA or SR?
If KA, 91 DOHC ECU needs 91-94 USDM KA24DE MAFS. IAT was for SOHC 89-90 only I think, and it is not a part of the MAF for any years regardless.
If SR, 91 ECU needs either the S13 JDM SR20DET MAF or 89-90 KA24E SOHC MAF. No others will work without ECU mods / fuel controller.
I don't think the G20 MAF works for either KA or SR - but I could be wrong. Sentra MAF doesn't work so I don't know why G20 would.
