in the future, please do a search. but to answer your questions;
you cant use your stock auto, you can source an SR auto though if your willing to go through the trouble.
a redtop is from the older s13 cars, the black top is from the newer s13 cars and from the s14 and s15 cars, with slight differences depending on what car it came from. the redtop is most peoples choice because of cost reasons. the s13 red/black top motors (supposedly) have a better flowing head than the s14 blacktop, but the s14 blacktop has a slightly larger turbo.
as far as purchasing a motor, i recommend the following people:
http://www.underground-motorsports.comh ... rtrend.com
I know the owners (Undergrounds owner, chris, is an awesome guy, know him from many phone convos, etc. wayne at phase2 is awesome too, i did his website design, so i talked to him a little bit, and what ive gathered, hes really good guy) of both those places and theyre both trustfull. I personally would try out Underground since theyre a knew company (if I was purchasing that is) since the owner seems to have his heart in the right place, and since hes so new, hes willing to cut deals to get business. Phase2 has decent prices and EXCELLENT quality (as wayne's reputation says, i dont know from personal experience).
As far as install in texas, cant help ya much there.
