Well as far as the wiring conversion from DPFI to MPFI... I've talked to a bunch of places online that do it for you, but they require your core wiring harness in order to modify it...
So that would require a lot of down time for my car, and a lot of hassle for me. So, when the time comes, I'm going to attempt it myself.
It is going to be a while before I do ANYTHING though, cause winter is fast on its way, and I can't work on my car too much in winter since I don't have a garage or anything to work in... Hell, it hasn't even stopped raining long enough for me to try and put my 99 LS seats in.
On that note, that's why I decided on the B18A1... I'm going to find as much integra stuff as I can change out or put in my car.
