Name that year intake

I got this motor off CL for $50.00 but it was not intell I got it home did I realize that it is a non EGR and non vac advance distributor. I have a 1991 Metro which I bought which has an EGR and a vac advance distributor but there are plugs that are not plugged in (see pics below) nor any plugs to plugs to plug in. I like the looks of the non EGR motor, it looks a lot cleaner. I am not sure if it will even work tho.

With that all being said, can I put the non EGR motor in and have it work with the computer? Did the 1991's even have this EGR intake stock or did someone before me change engines/head and intake? If it will work will is there any pro's of cons to running a non EGR engine (besides the emissions)? Any MPG gain?

Thanks for any and all input!

Geeze, post after post just hammers home how little I know. I thought EGR and electronic advance went together as a matched set. Here we have an engine with no EGR and electronic advance, and an engine with vacuum advance and EGR! I didn't even know those combinations existed. According to what I thought up until about 30 seconds ago, a 91 LSI should have no EGR and a vacuum advance distributor. If you still have your original hood, a sticker on the inside f the hood should spell that out for you, tell you exactly what emissions devices should be there, and show you the vacuum line routing. It's possible that your original engine has had the distributor replaced with the wrong one, and you're driving around with no advance.

Whatever, you need to keep the setup that the car originally had in order to keep the computer happy. Normally you don't change the intake, throttle body, and distributor. That all stays with the car, you just change the block and head.

The hood has been repainted and all stickers have been removed or painted over. So I am kinda at a loss here Woodie. This is my first Metro and not really sure what bag of worms I have got myself into here. The thing that makes me think that maybe this intake was replaced is this plug that has nothing plugged into it as well as the EGR valve.

Swap the intake manifold and throttle body and distributor from your current engine installation to the "new" one and you'll be fine.
