I will have to keep you guys posted on the sales status. Right now I got a guy saying he will paypal the money on Friday morning for the frame, fork, hs, bb. But until the money is in the account everything is still up for sale. I have another guy from a Scion forum that I just sent photo's to this morning that might be interested in all I have left for like $225 so I would obviously prefer to go that route.
If it is an EX it should have what ever motor came in it that year. I believe it is a 1.6 as the older Integra's and the newer RSX came with the 1.8L motors. And yes, the hourse power at the wheels is always less than engine rated hp. This is due to drive train loss largely.
As far as the salvage title, I would not be worried about that. If you are really concerned, you can ask your parents about a good mechanic or whoever they take their cars to have work done on them and see if you can bring the car to them to check it out for you. It may cost you a little bit of money (1-200) but it could be well worth it. I would mainly be concerned about frame damage if anything. The salvage title will mainly affect you when you try to sell the car down the road.
