Joking aside my friend, to answer your first question, Eg civics in general sell for between 900k and 1.1 million depending on condition, options, mods, rice etc. as for the two door (Im assuming you mean a hatchback since we dont have the coupe here), they are rarer than the proverbial "Hen's teeth" because they were never imported in large quantities like the 4 door. Most 2 doors around are the legendary high performance SIRs , and almost all of those are used as race cars now. There WAS a 2 door standard hatch being advertised in the papers for a few weeks, you can check that out.
As to your other questions, like devinda pointed out you might not get a lot of help here since most members take a dim view of the sort of modifications you are proposing to do.... For your information, adding a huge body kit to an EG8 is only going to give a negative effect to the performance of the car, and it'll hurt it in other ways too, such as increased wear and tear and also high fuel consumption. This is all a result of the weight.
Therefore you would be much better advised spending that cash on some performance modifications (if you must have an Eg8 that is)... or if you're looking for Real performance, about the same amount of money that an EG plus mods will cost can get you into a Lancer Evolution III, which can eat an Eg8 for breakfast......
Hope this helped
Cheers
