Yes, I agree that running lines to a common location (a box in this case) and mounting the MAP sensor there is a better idea. I am not sure how much vacuum you will get, but it's better than trying to plum 4 hoses into a map sensor.

Also, you have to consider that there are things on the car that work off of vacuum. The box is also a good idea because you will need to make ports for the brake booster line, the EGR, and whatever else needs vacuum. Again, I am not sure how much vacuum you will see from this kind of setup, hopefully it will be enough. But, if it isn't you can run a vacuum pump of some kind (this is what diesels do).

I think the IAC problem will be the most diffucult problem to overcome. I'm not saying it won't work, I think it will, but I think it will be tricky.

How is it done on the 4 TB kit sold for Neons? Someone out there must know.
