if the IACV is busted one from a sr20de sentra will work too. I thought mine was crapped out and changed over to one. I think it was 91-92 motor I got it from.

What kind of issues are you having? I've got a 25 and am having problems with mine too. Is this IACV from the sr20de good on rb25s too? Mine idles super high and the only way to keep it around 1k or 1200 is to turn the screw all the way in on the IACV. I replaced the tps and that didn't help.

It might have to be a newer one maybe. 95-99 Sr20de might have the same foot print tho I'm not 100% sure. I know the SR20DE from the 91-92 was the same and worked.
