First off, welcome to the site!

Secondly, check out the following article: http://bszopi.net/drupal/content/Gen..._3_TopEnd_Swap

Its actually for a top-end swap, but some of it may be applicable to what you are trying to do. It is pretty much a simple swap, though....

Oh yeah, and here is another good resource, although it is more centered around J-bodies (Cavalier, Sunbird): http://www.domesticcrew.com/installguide.htm

Your best bet would be to use the original 3.1 harness and computer, you'll have to figure out the mounts but it shouldn't be too hard. Your 3.1 exhaust manifolds will bolt right up to the 3100, just make sure to use a new set of 3.1 gaskets with the round ports.

going from a 3.1 to a small port 3100 isn't a huge jump in power, your stock 3.1 chip should run the 3100 just fine. Use the injectors from the 3.1 though.
