I want to say you'll be okay. I'd have to look at the 96 intake mani I have laying around to be sure. If my memory is correct that 96 didn't have the IAC valve porting. BUT that could be from it being a JDM engine. It seemed to have the same sensors besides that.

I can confirm, maybe Friday or Sat if you'd like though.

I won't have the head back from the shop for another week and I won't be able to hit up the junk yard until Tuesday at the earliest, so that's cool.

The 99-00 Manifolds have an extra air injection system built into them, with these tiny little ports that WILL leak air and cause ridiculous idle surge if you try to attach it to anything other than an OBD2b head.
For anyone interested, it's called the fuel injection air control system, and it's unique to intake manifolds on 99-00 D16Y8 engines.

Hobo, you'll be fine with a 96-98 IM. If you find a 99-00 you're just going to have to weld up those damn air holes. Stupid fuel injection air control system
