Sounds great. Good place to start for new folks. One question - why does S2 limit to 5 speed tranny? Considering power is capped, no FI...seems like 5 speed would be the optimal choice and 6 speed wouldn't give any benefits, so why not allow them? Just dreaming here, maybe one day i could join, but this would mean swapping out my stock 6sp from NB2.

For any other questions regarding prep I would encourage you to not post the questions but actually take the time to read the entire rule set. Everything is very clear and laid out. We are pretty emphatic about not spoon feeding scattered questions but instead directing everyone to read the rules thoroughly before you start bolting a car together. That will answer most of your questions.
The short answer though is no, what you propose would not be legal in S3.

in case it wasn't clear, S3 is a feeder class. We will do nothing to really grow the class. It is intended for new drivers to be able to purchase existing cars, get their feet wet then modify an upgrade to S2. We do not expect or really want people to build cars specifically for S3.
For a few more bucks you have an S2 which is way faster, has 4x the field size, prizes and a championship.
