ok guys ive seen a basic start car for my replica eventually i want it be a rst complete

what suspension drop should i get?
what exhaust would be best as it will be a replica for a while i want something to realy sound like a rst? i was thinking maybe 2 4" exits either side of the back?
i think its a 1.2 1990 escort bonus is this ok for converting?
what would i be looking to pay for spraying bonnet front bumper rear bumper skirts(basically the bodykit) or should i get a full respray?
wheres best to look for the above aparts and what should i be looking to pay thanks alot
