:wavey: those are some excellent questions!!! no noob sticker for you... :exnbp:
just to add on to what everybody else said, motor swaps from 3rd gen integras to the 6th gen (96-00) civic are easily done with a few modifications and some rewiring, but these engines are almost a simple drop in for 5th (92-95) gen civics. most major components are interchangable between the integra and civic of these years.
i have changed over the motor, suspension, and brakes of a 96 GSR integra into my 96 civic hb without any need to modify the body or frame. brakes and suspension was a simple bolt on, but the motor took a little more time.
on a car audio stand point, honda/acuras are more forgiving and easier to work on when it comes to installing systems/amps/alarms/multimedia systems. the wire colors are simple to read just like VW's. there is plenty of room to work with behind the dash unlike most VW's and panels come off with great ease.
just as a little welcoming tip, this board is essential biased towards modifications that demonstrate functionality and subtlety. we love clean cars, usually credit those who try new innovations even if it doesn't suit our own taste, and we LOVE to flame ricers!!!! enjoy and welcome... :yay:
