Different ISC housings or adapter/Swap FITV? 6 bolt 2g

[Fayt]

I'm hunting down my idle surge problem, and I've come to a snag with my ISC. As I was rebuilding my 1g throttle body, I noticed the 1g metal ISC motor and housing only has 2 screws, but my 2g black ISC that is 100% working has 3 screws. Am I missing something like an adapter or a sleeve? Or do I need a different FITV/ISC housing to use the working 2g? This 1g ISC also has a short harness on it, while my other just has the open plug. This is a 6 bolt swapped 2g. The 2g does not fit into the housing at all.

The metal isc is from a 90. The throttle body is totally different.

You can use the ISC from a 1g as long as it is not from a 90',

Which by your description of the harness coming from the ISC motor, Sounds like a 90' Piece.

Hope this helps.

Strange, the rest of the throttle body is a normal 1g, has 4 ports on top... the FITV is also a 92-99 as you can see in the pictures. So any other 1g ISC should bolt right up?

So for one like this Mitsubishi Eclipse 95 99 96 97 IAC Idle Air Controller E9T15271A | eBay is the tan part replaceable with my black ISC, or is it a single unit?

Would I be better off getting one this style Mitsubishi Dodge Eagle Hyundai Plymouth Idle Air Control IAC Valve E9T15292C | eBay

The black one is an EVO ISC. All 1g and 2g ISC have 2 bolts. The one in the 1st ebay link is the old style , the black one in the 2nd link is the revised one either will work but the black one is the newer one.

Thanks synthetek for clearing that up. I guess I have no idea where/how I got that black ISC .

 

[synthetek]

Looking again I am not sure that's an EVO ISC but they do have 3 bolts , it could be from something else but its not a 1g or 2g.

it could be from something else but its not a 1g or 2g.

This. I don't know what that is, but it's not a DSM ISC.

Hate to revive an old thread... but i came across this thread after trying to loot lots of different mitsu cars and i recognized the questionable part.
I believe the black one in the last photo in OPs post is the one i saw on a mirage. The throttle body has the housing on those. I took it off hoping that i could swap over into my busted isc housing, and it looks like the coils might match (if anyone wanted to be adventurous enough to tear it apart and resolder the coils), but the housing won't mate.

Since ya brought it up, that also looks like the isc for a 3rd gen (2000-2005) eclipse.
